【 摘 要 】

In this study we analyzed application of two types reinforcements of the polymer matrix composites (PMC): (1) fabric prepreg, (2) unidirectional prepreg and their hybrids for production of modern snap-fit joints. The numerical calculations were made in Abaqus program. Moreover, different layer systems and geometries were proposed to get the most effective joints. For each kind of joints the opening forces were assessed and Tsai-Hill strength criterion for estimation of a damage parameter inside of the PMC was applied. The proposed methodology leads to designing of more optimal joints for various engineering structures.
