We know that fiber-based composites are directional dependent, What happens when the load is applied in the normal direction? If fiber is strong enough, whether it will give the same results irrespective of the direction?

Good work and my best regards, Pierluigi Traverso.
Dear all, I have a small addition to what Dr. Pierluigi Traverso recommanded. When fibers are unidirectional, stress testing in normal direction to the fiber is done mainly to test how is the interface fiber-matrix, i.e., the state of adhesion at the interface and its coherency in stress transfer. My Regards
I agree with Mr Bouaziz. The load bearing of a composite part mainly depends on the fibers orientation. To have a good understanding of the effect of fiber lay-up, there are many references on laminate theories that explain the relation between fibers orientation and resulting mechanical properties. At transvres direction, the load is transferred from matrix to fiber, but limited by the stress concentration at interface and depend on the compatibility between them.
