1. INTRODUCTION
Over the past several decades, industrial grade composite wood based panel (CWP) have been
recognized through the furniture industry as an ideal substrate for Mcp constructions, utilizing
various types of overlay surfacing and edge banding materials. Edge banding is perceived as
the most important accessory and protective in furniture making. There are various types of
edge banding materials such as polyvinylchloride (PVC), acrylic, acrylonitrile butadiene
styrene (ABS), melamine, solid wood or wood veneer comprise the types of edge banding
materials. During the past decades, there has been successful work accomplished in the
(CWP) industry. Lee and Kim [1] found out that there was a significant increase in the
modulus of elasticity of wood based composite panels due to coatings. Nemli [2] examined
the effects of melamine-impregnated papers coating on the properties of particleboard and
stated that surface coating improved the physical, mechanical properties and decreased the
formaldehyde emission of particleboard.
The purpose of edge banding will be to suppress the absorption of water and humidity and
providing a contrasting finish for all decorative surfaces [3].
Interior fitment and furniture manufacturers are applying widespread ratios of decorative
composite edge banding materials for (CWP). CWPs are mostly used in construction of home,

office and school furniture. The purpose of edge coating of CWPs is to suppress the
absorption of water and humidity, and esthetic [4]. The performance of the coated panels is
depended on quality of CWP and the type of coating materials [5]. While particleboard and
medium-density fiberboard make ideal substrates, the manufacturer must pay attention to the
many factors that will affect surface quality in virtually every step of manufacturing process
[6].
Özçifçi [7] studied some corner joints obtained from particleboard, and covered their edges
for case furniture with massive wood. Then, ‘‘L” test samples manufactured and jointed with
dowel, rebated, tonque-and-rebated joint types by using polyvinyl acetate (Pvac) (Vinyl
Acetate Homopolymer) adhesive. In the test, compression and tension strength tests were
applied on the bonding area. As a result, the highest compression and tension strength were
obtained in dowel joint.
Uysal [8] investigated the effects of the thickness of solid wood edge banding strips and the
dowel diameter on the withdrawal strength of beech dowels in particleboard. Withdrawal
strengths were measured for the prepared test samples and the highest withdrawal strength
was obtained in particleboards with12.0 mm edge banding thickness and with 6.0 mm
diameter dowel.
With the start of production of MCP and PVC edge bands bleating technical, aesthetic and
economic reasons, has gained a very high demand. Pvc edge bands used intensively on
furniture industry. Studies in the literature examining the effects of time and temperature
based on the mechanics worked on this issue due to insufficient. This study time limits 20, 30,
40 and 50 days, teperature limits +35°C to -5°C
Unaged IB and aged IB values of all the treated specimens at three retention levels
significantly decreased when compared to untreated control values. The IB strength and bond
durability of all the treated panels decreased with increasing chemical content [9].
Özçifçi investigated the role of geometry on the mechanical performance of scarf joints in
laminated veneer lumber (LVL) bonded with phenol formaldehyde and melamine
formaldehyde (MF) adhesives. It was observed that the highest bending strength
(291.5N/mm2) and modulus of elasticity (28101N/mm2) were obtained in control (solid
wood) samples having three layered LVL, jointed with 30° angle and bonded with MF
adhesive. As a result of the effects scarf joints on bending strength and modulus elasticity test,
if the scarf angle decreases, the properties of LVL increase [10].
Güntekin studied some mechanical and physical properties before and after accelerated aging
tests of the cement bonded fiberboard made of using Calabrian pine fibers. Increase of density
and percent of accelerators used generally causes an increase in mechanical properties.
Percent accelerator also caused an increase in TS and WA. Increase of fiber / cement ratio
resulted in an increase in MOR, TS, and WA while a significant decrease was observed for
modulus of elasticity [11].

Yıldız et al. studied the effects of heat treatment on compression strength (CS) of spruce
wood (Picea orientalis). This study indicated that the changes in the chemical structure of the
treated wood were determined by analyzing contents of cellulose, hemicelluloses and lignin.
Heat treatment was applied on the test samples in an oven at four different temperatures (130,
150, 180 and 200 1C) and three different durations (2, 6 and 10 h) under atmospheric
pressure. The results indicate that the effects of heat treatment on CS values generally
exhibited a decrease with increased duration and temperature. It was observed that
hemicelluloses were the wood-cell components most degraded by the heat treatment [12].
The tests of Mirski et al’s showed that PF resin modification with diol esters makes it possible
when maintaining identical pressing parameters to manufacture particleboards with improved
mechanical properties and enhances water resistance in comparison to the control board
resinated with pure PF resin. The application of diol esters as modifiers of phenol resin makes
it also possible to produce at reduced temperature or shortened pressing time particleboards
with good mechanical properties and high water resistance [13].
Papadapoulos Antonious studied physical properties of conventional particleboard bonded
with amounts of UF and PMDI resin and examine the effect of mat moisture content (MC),
wax content and platen temperature on their bonding efficiency, as determined by internal
bond strength. It was found that PMDI not only gave superior board properties compared with
the UF, but the amount required was reduced considerably as well. The MC of the mat and
the platen temperature did not significantly affect the bonding efficiency of PMDI bonded
boards, but the bonding efficiency of UF bonded boards. The inclusion of 1% wax
significantly affected the bonding efficiency of both resins; however the loss in strength was
higher in UF than PMDI bonded boards [14].
P. Bekhta et.al. studied on Short-term effect of temperature on bending strength of wood-
based panels. Accordig to this study; Bending strength of different wood-based panels such as
particleboard, MDF and OSB has been studied at temperatures between +20°C and +140°C. It
was found that the temperature for all studied panels significantly affects bending strength.
After one-hour effect of the temperature 140°C the bending strength of panels is reduced (in
comparison to the temperature of 20°C) [15].
Kakaras and Papadopoulos found that the internal bond strength was significantly increased
by increasing the drying temperature. This was attributed to the breakdown of the particles
dried at high temperatures [16].
Increasing the resin content definitely improved the performance of the specimens, apparently
because the extra binder increased the resistance of the board to springback and differential
shrinkage stresses [17].
One year investigation on the ageing effect and long term performance of Cement Bonded
Particle Board the results from stage 1 showed that both strength and stiffness of Varco
cement bonded particleboard were increasing consistently although the test results showed
much better performance than those required in EN standards [18].

Heating wood changes the properties of wood. It can decrease the higroscopicity and improve
the dimensional stability and decay resistance. A variety of thermal modification processes
have been developed. The results of the process depend on several variables, including time
and temperature, treatment atmosphere, wood species, moisture content, wood dimensions,
and the use of catalyst [19].
Hygroscopic building materials can absorb and release moisture, thus dampening the indoor
humidity variation [20].
The moisture buffering effect of the wood paneling is related to its moisture responses at the
room level [21].
Bending Strength of uncoated particleboard is 18.29 N/mm2 and melamine coated
particleboard is 19.96 N/mm2 [22].
It is well established that the board density is one of the most important variables in
determining the strengths of particleboard. In particleboard, the intimate contact among
adhesive-coated wood particles is prerequisite for forming bonding among the particles.
Raising the board density increases the intimate contact of the particles, thus increasing the
strengths of the particleboard. However, if the density is high enough to allow all wood
particles too intimately contact with each other, further increase in the density would not
increase the strengths any more [23].
Specific mass of the plate is one of the factors that most affect the physical and mechanical
properties. Particleboard with the increase of the mass of a specific thickness swells improves
all other aspects except for dimensional stability. Specific mass as a result of increased
contact between chips is much more powerful [24].
2. MATERIALS AND METHODS Materials Particleboard is produced by mechanically reducing the wood raw material into small
particles, applying adhesive to the particles, and consolidating a loose mat of the particles
with heat and pressure into a panel product [25]. Mcp is typically made in five layers. The
uppermost faces of the board are thin melamine; the layer under the melamine consists of fine
wood particles, then the core is made of the coarser material. Melamine coated particleboard
is used for furniture, case goods, and home decoration where it is typically overlaid with other
materials for decorative purposes.
Eighteen millimeter thick Mcp was selected for this study due to its wide-use by the Turkish
panel furniture manufacturers. Production Date: 11th. June, 2012, mixing properties
(Wooden): pine, beech, oak and a bit of waste wood, Mixing properties (Chemical): UF glue,
wax and hardener, Density: 659Kgr/m3 Mcp which 18 mm thick, 1880 mm wide and 3660
mm length full-sized board sheet was obtained from one of the wellknown Mcp producers in
Turkey. First cut into strips. These strips were subsequently cut into the desired member
lengths. Members for joints were randomly selected from this common supply. Melamine

coated chipboard produced according to TS EN 312 (17.03.2005) [26]. Approximately 95 %
of the lignocelluloses material used for particle board production is wood [27].
Hot-melt adhesive used in this study is a thermoplastic-based synthetic resin. Its application is
recommended in locations subjected to 8–10% relative humidity. Hot-melt adhesives are
environmentally friendly glues containing no solvents. They find key applications in the
manufacture of office and home furniture, particularly in the edges of various types of edge
banding materials such as wood and wood veneer, (PVC), acrylic, (ABS), melamine for table
and cabinet furniture. They are solid at normal ambient temperatures and need to be heated to
a liquid state before bonding. They have to remain sufficiently fluid to wet out the two
surfaces during bonding. As the adhesive cools, it will revert to its solid state, completing the
bond. With hotmelt adhesives, the change from solid to liquid is reversible, and controlled by
temperature. Wood and wood composite should be dry enough so that even if moisture is
added during bonding, the moisture content of the product is at about the level expected for
the assembly in service [28]. Adhesives are used to hold two materials together; thus, the
viscoelastic dissipation of internal and external forces is the most important aspect of
adhesive performance. The effects of internal forces are often not considered, but such forces
can be very high in wood [29]. Adhesive failures are generally the result of using weak edge
banding procedures during manufacture rather than the adhesive having an unreasonably low
softening temperature [30].
Melamine is a private paper that is initially impregnated and then covered with lacquer.
Impregnation is a process in which the paper is absorbed with resin and coated with lacquer
surface. Meanwhile, the paper strength and durability wins. It must be emphasized that
melamine is a special surface covering material that has high resistance to impacts, scratches,
and abrasion. Additionally it is flexible and suitable for surrounding corners [31]. Melamine
edge bands which Thickness of 0.4 mm and width of 22 mm are affixed with an iron
temperature of 200 °C.
PVC edge banding is manufactured with premium quality resins and high-impact modifiers
that produce a product with excellent machinability, impact resistance, durability, and overall
appearance. Thickness of (0.4, 0.8, 1.0 and 2.0) mm and width of 22 mm produced by Ersa
Mobilya ve Plastik Sanayi ve Ticaret Ltd Şti., Ankara. PVC edge bands glued with hot-melt
adhesives on auto edge banding machine. The temperature of gluing was at 200 °C and the
feed speed of the machine was 12 m/min. The edge banding machine bonds the edge banding
to the substrate, trims leading and trailing edge, trims top and bottom flush, scraps any surplus
and buffs the edge. The adhesive is applied to only edge surface of Mcp, using 214 g/m².
Edge bands types and thicknesses are indicated in Figure 1. Number of 1 is non banding, 2 is
0,4 mm melamine, 3 is 0,4 mm PVC, 4 is 0,8 mm PVC, 5 is 1,0 mm PVC, and 6 is 2,0 mm

2. Temperature ranges and transition periods; Within 7.30 hours from +35.6 °C to -5.0 °C
Test sample preparation 1. Representative parts to obtain: during the cold and hot application process; test specimens
were obtained 20th
day from the doors, 30 th
day from shelves, 40 th
day from right sides, and
the last 50 th
day left sides of cupboards.
2. Obtaining the test sample: 20th, 30th, 40th ve 50th day’s bending and tensile strength
samples used for experiments were obtained by cutting with circular saw machine.
3. Packaging and transport to the test place: The test samples given in date and serial numbers
coated with polystyrene and packed in corrugated cardboard boxes where transported by
cargo experimental scene.
By using of (Mcp), non banding control sample, two different types of edge banding materials
(PVC and melamine), four edge banding thickness (0.4, 0.8, 1.0, and 2.0 mm) for PVC, and
one edge banding thickness (0.4 mm) for melamin, for bending strength test, a total of 192,
and for tensile strength tests, a total of 216 samples were prepared.
All tests were carried out on a universal testing machine, which have 7 tons capacity in the
Furniture and Decoration Research Laboratory at the Faculty of Technical Education,
Dumlupınar University, Turkey. A rate of loading of 6 mm/min was used in all tests. The
loading was continued until separation occurred on the surface of the test samples. The
maximum bending and tensile strength were determined as the force applied to each
experimental sample at the time of failure. The result for each of the samples was displayed
by the computer to which the test device was connected.
Specific gravity values of Mcp wehere calculated following ASTM Standard D 2395-93 [32].
Moisture contents were calculated on the same specimens and followed ASTM Standard D
4442-92(2003) Direct Moisture Content Measurement of Wood and Wood-Base Materials
[33].
Data analyses and experiments The first important factor is type and thickness of edge banding material, and type of time. In
this respect, the multivariate analysis of variance results for bending and tensile strengths
values for Mcp according to time, edge banding type and edge banding thickness are
presented in Table 1 and Table 2.

In previous studies bending and tensile strength of the wood and wood composite materials,
and the rates were applied to investigate the various additives. The resulting wood composite
materials with different mechanical and physical properties were observed. In those studies,
usually much higher temperatures were applied.
In this study, different indoor temperatures between -5 and +36 °C were carried out covering
different regions of Turkey. In contrast to the previous studies this pointed out a decline in
mechanical properties. This study indicates an increase in mechanical properties.
Edge band type, thickness, and the effect of heat treatment of the application for bendig
strength increases totally 99% and tensile strength increases totally 139%.
