摘　　要：比较了缝纫、无缝纫层合板力学性能差异,同时考虑了缝纫引起的厚度变化。通过拉伸、压缩试验研究了缝纫对层合板及含孔板的拉伸、压缩强度和破坏机理的影响。研究结果表明,缝纫带来的厚度变化影响了面内纤维体积含量,这对评定缝纫层合板力学性能至关重要。The mechanical properties of the stitched laminates were compared with those of the unstitched lamihates, considering changes in thickness due to stitching. Experimental investigation was conducted to understand the effect of stitching on tensile strength, compression strength, open hole tensile strength, open-hole compression strength and failure mechanisms. The results show that the change in thickness due to stitching affects the volume fractions of in-plane fibers, which is important to assessing the mechanical properties of the stitched laminates.
