Résumé :

This study puts in evidence the effect of the change of the arrangement of the reinforcement(unidirectional, woven fabric and mat) on the rupture of E-glass/epoxy composite material. The consideredlaminates are symmetric of stacking sequence [+θ/- θ]3S and subjected of uniaxial traction loading. Amathematical approach based on failure criteria was used. The comparison of their behavior allows us to proposehybrids capable of improving the mechanical performances of composites, of decreasing the material anisotropydegree and to have consequently optimal structures.
