本文提出了复合材料层合板的立交层间剪切强度的概念,和测定正交层间剪切强度的方法。正交层间剪切强度低于单向复合材料的层间剪切强度。文末还说明了,利用测定的正交层间剪切强度来分析正交铺设层合板短梁的极限载荷是合适的。
This paper presents the concept of interlaminar shear strength of composite laminates and the method of determining the interlaminar shear strength. The interlaminar shear strength is lower than the interlaminar shear strength of unidirectional composites. At the end of the article, it is also demonstrated that it is appropriate to use the measured orthogonal interlaminar shear strength to analyze the ultimate load of the cross-ply short beams.
