Nondestructive evaluation and optimization of composite material CFRP/GFRP layup

The article presents a parametric studies of different arrangement of combined composite carbon fiber reinforced polymer/glass fiber reinforced polymer (CFRP/GFRP) in determining mechanical properties of modulus of elasticity. Apart from value of All (extensional stiffness), other mechanical properties such as B11 (extensional-bending coupling) and D11 were also computed. It is performed analytically using MATLAB version R2012b and validated by using eLamX2 software. The outcome of the analytical simulations shows that, the higher number of CFRP ply in composite laminate, the higher elastic modulus. Bending stiffness of composite laminates also increase if CFRP ply position is at the outermost of composite laminates.
