Anti-symmetric laminates cannot exhibit any coupling other than extension-twist (together with shear-bending).

WebThe composite material forms are limited to continuous fiber or discontinuous fiber-reinforced composites in which the laminate is balanced and symmetric with respect to the test direction.
