摘要
本文通过复合材料层压板拉伸和剪切实验,研究了常温和湿热环境下缝合层压板的性能。根据试验数据及观察结果,探讨了缝合层压板的性能下降的原因及损伤破坏机理。试验及分析结果表明湿热和缝纫形成的富树脂区影响是层压板高温湿热环境性能下降的两个主要原因。
Tensile and shear property of stitched laminates at room temperature and in hygrothermal environment was studied. Micrographs of fracture appearance been discussed. It is concluded that hygrothermal environment and initial crack in resin-rich area were prime reason for performance lost of stitched laminates.
