复合材料Z-pin的压缩试验研究
Experimental Studies on Compressive Properties of Composite Z-pins
摘要
Abstract
The axial compressive behavior of three kinds of composite Z-pins was investigated. The ultimate compressive stress and failure modes of composite Z-pins with different length were analyzed. The results show that carbon fiber Z-pins with the diameter of 0.50mm have the best compressive properties. Those with the diameter of 0. 28mm are apt to be buckled. And aramid fiber Z-pins are easily failures on the contact point. Theoretical predictions of critical stress of carbon fiber Z-pins agree well with the experimental results , but the experimental value of the critical stress value of aramid fiber Z-pins is lower than the theoretical value.关键词
