The material of composite is one of the most widely used material when strength to weight ratio is considered, this make it more ideal material in the space-air craft industries where strength to weight ratio is more important. The in-plane and out - plane i.e. bending and twisting constants have been derived in terms of properties of elasticity of individual laminate and its thickness. The staking sequence and its orientation also play a role. Thus knowing the elastic property, the thickness and orientation of individual ply we can get the elastic properties of composite laminate.
