1.前言由文献[1]得知,正交层间剪切强度比单向层间剪切强度低得多。在本文中作者进一步工作表明,由不同铺层方向构成的层间,其表观剪切强度具有一定的规律。按照国标,测定单向层间剪切强度的方法有短梁剪切法和压剪法。作者先用短梁剪切法测定中强碳/648环氧材料由不同铺层方向构成层间的剪切强度,采用了[0_m/θ_n],
1. Introduction According to [1], the interlaminar shear strength is much lower than the unidirectional interlaminar shear strength. In this paper, further work by the author shows that the apparent shear strength of the layers composed of different layers has certain rules. According to the national standard, the method of determining the unidirectional interlaminar shear strength is the short beam shearing method and the pressure shearing method. The authors first use the short-beam shear method to measure the shear strength of the middle-strength carbon / 648 epoxy materials from different lay-up directions, using [0_m / θ_n]
