摘要: 本文对复合材料层压板进行了不同连接形式的连接强度试验研究，获得了铺层比例、厚度、湿热环境和连接形式对复合材料层压板连接强度的影响规律。研究表明：对于单钉双剪连接形式，当±45˚铺层比例处于一定范围内时，适当改变±45˚、0˚和90˚铺层的比例并不会对复合材料层压板的连接强度产生较大的影响；对于单钉单剪连接形式，当±45˚铺层比例处于一定范围内时，铺层比例并不是影响连接强度的主要因素，层压板厚度对连接强度有重要影响。
Abstract: In this paper, the experimental study on the connection strength of composite laminates with different connection forms is carried out, and the effects of the ply ratio, thickness, hygrothermal envi-ronment and connection forms on the connection strength of composite laminates are obtained. The results show: For the single nail double shear connection, when ply ratio of ±45˚ plies is in a certain range, changing the ratio of ±45˚ plies, 0˚ plies and 90˚ plies properly will not have a great impact on the connection strength of composite laminates; For the single nail single shear connection, when the ratio of ±45˚ plies is in a certain range, the ply ratio is not the main factor affecting the connection strength, but the thickness of laminate has an important influence on the connection strength.
