Let the material properties of the particle and matrix be:
Particle-E-glass: E,,11,, =80 GPa,  v,,12,,=0.2000  and

Matrix: E =3.35GP, ν=0.35 

Particle volume of fraction is assumed to be 50% 

The material properties are obtained from:
“Soden, P. D., Hinton M. J. and Kaddour, A. S., Lamina properties, lay-up configurations and loading conditions for a range of fibre reinforced composite laminates. Compos. Sci. Technol., 1998, 58(7), 1011”[[BR]]
