When MWK (Multi-axial Warp Knitted Fabric) composites are applied for the structures, the connections of each component using mechanical fastening are needed. The local contacts between the bolts and the composite laminates may induce high stress concentration in the laminates. In this study, stress analysis near the hole boundaries of MWK composite laminate are conducted with various geometric factors under different loadings. In the case of single and multi-pin loaded MWK composites laminates, the results show that the types of loadings and geometric factors of mechanical joints have a significant influence on the joint performances.
