Field Hockey Stick


Toe Length

• Hook

– Popular with defensive players due to the large

stopping surface; this helps receive the ball

– J-shaped construction

– Particularly good on grass surfaces

• Maxi

– Large receiving area and greater hitting power

– Defensive players prefer this stick style

• Midi

– Large hook surface and length

– Greater hitting and stopping area to aid receiving,

flicking, and reverse stick play

– Best for beginners and midfield players

• Shorti

– Designed to allow quick movement around the ball

– Generally used by offensive players


Length

• Traditionally senior hockey sticks have been 36 inches or 1 yard

long, the standard length has increased to 36.5 inches. At this point

in time there is no set restriction governing the maximum length of a

hockey stick but manufacturers tend not to produce many sticks of

more than 38.5 inches. However some manufacturers can take

special orders for lengths up to 42 inches.


• On defense, a longer stick is useful to provide a longer reach and to

allow the player to drive the ball further.

• On offense, a shorter stick improves a player's stick handling skills


Weight


How does a stick's weight affect its

performance?

• 19 - 20 ounces (approx. 540 - 565 grams) - Designed for

forwards, a lightweight stick doesn't interfere with, or

hold back rapid stick work.

• 21 ounces (approx. 595 grams) - Designed for

midfielders, a mid-weight stick benefits both defensive

and offensive maneuvers.

• 22 - 24 ounces (approx. 620 - 680 grams) - Designed for

backs, the heavier sticks put serious power and distance

behind your shots, making them great for clearing the

ball.

4.Composite + Wood


Composite Materials • Fiberglass

– Light weight used for offensive players

– Durable and less rigid

– The material prevents wear and tear on the stick.

– Cheaper

• Carbon

– Provides a boost in hitting.

– One drawback to adding carbon to a hockey stick is how it reacts in

frigid temperatures.

– Following a hit, the vibration can be felt throughout a player's body.

– More expensive

• Kevlar,

– lessens the vibration by absorbing the shock of the hit to the toe of the

stick.

• Dyneema

– acts like a giant shock absorber.

– The coating is usually added at the base of the shaft. 06/03/2013 Engr. Shan Imtiaz

• Varying levels of composites alter the

Conventional vs Composite

• Wood

• Cheaper

• Softer feel

• Poor consistency

• Moisture effective

loss of power

• Composite

• Greater power

• Consistency (weight,

stiffness and power)

• Harsher, less refined

feel for the ball

• Expensive


Manufacturing

• A hockey stick is produced in two parts—

the blade and the shaft.


Composite Field Hockey Stick

1. Several layers of the composite material (fibers that

have been pre-saturated in epoxy resin) are wrapped

around a mold in the shape of the stick shaft.



2. Heating and pressing the unfinished stick

shaft. There are several ways to do this.

Conventional methods include placing the fiber-

wrapped shaft in a mold of a similar shape. The

composite material can then be pressurized

and compacted

– by applying hydraulic pressure to the shaft,

– by using vacuum pressure to force the composite

material against the mold or

– by using an inflatable device to force the composite

material to push against the mold.



3. Attach the stick shaft to a blade by

coating the peg on the end of the stick

blade with hot glue and clamping it into

one end of the shaft. Insert a rubber plug

into the other end of the stick shaft. Leave

the finished stick to dry.


Field Hockey Ball • A field hockey ball is required to be spherical,

• Weight between 156 and 163 grams

• Have a circumference of between 224 mm to 235 mm.

• The ball can be smooth or dimpled.

• Smooth Balls are usually used for Indoor (could be used

for outdoor training)

• Dimpled Balls are usually used for Outdoor. so that it

runs smoothly along the turf.

• A field hockey ball is made of all plastic. The plastic

depends on the weather and field conditions.

Polyurethane balls will not shatter under cold conditions.

Vinyl balls are great for hot weather, but freezing

conditions could make the ball crack and break.
