COMPOSITES MATRIXS

CORE

• Providing

structural strength

• Bonding element

• Hold the reinforcement in

desired position

• Giving strength

• Transfering/ Distributing

stresses

• Act as central members

• Giving more compressive

strength to the structure

•Adding thickness without adding

weight
