Although composite materials are widely used, many problems remain to be solved. This study derives the in-plane and transverse strength and shear stiffness of unidirectional fiber-reinforced composites from torsion experiments on rectangular cross section bars, using Lekhnitskiis equations. An equation is derived, to obtain the transverse stiffness and shear strength as a function of the fiber angle. The non-linear behavior and fracture strength in torsion of rectangular, antisymmetric angle-ply laminate bars were predicted. The predictions agree relatively well with experimental results.
