摘要
针对1K缎纹碳纤维织物/环氧复合材料层板销钉连接,实验研究了几何参数对连接性能的影响。选取了不同的端距和边距,测试了碳纤维织物复合材料层板W/D(试样宽度/孔直径)及E/D(孔端距/孔直径)对销钉连接强度的影响,并分析了销钉连接的破坏模式。实验结果表明:1K缎纹织物/环氧复合材料层板销钉连接承载能力随着边距E和端距W的增加而增加,当E/D=2,W/D=3时,销钉连接强度达到稳定值,此后增加边距E和端距W值连接强度不会有明显的增加。
The effect of specimen width-to-hole diameter ratio (W/D), and the ratio of edge distance to hole diameter (E/D) on the bearing strength of satin carbon fabric/epoxy composites was performed experimentally. Single-hole pin-loaded specimens were tested for their tension response. Failure propagation and failure type were observed on the specimens. The influence of the joint geometry on the strength of the pin-loaded composites was assessed. The experimental results show that the load capacity of carbon fabric reinforced epoxy laminates with pin connection was increased by increasing W and E. However increasing the E/D ratio beyond 2 and increasing the W/D ratio beyond 3 have an insignificant effect on the load capability of the connection.
