单向复合材料性能的比较本文讨论了单向纤维复合材料的横向性能和界面性能,比较了各种试验技术,评述了试件非界面损防致使短梁剪切实验不精确,提出横向拉伸试验是一种较好的试验,并解释了横向界面破坏的原因。通过检测两种复合材料,比较了两种技术,结果表明,用横向拉伸试验可灵敏地检测出不同界面性能的破坏能量。 Comparison of properties of unidirectional composites In this paper, the transverse properties and interfacial properties of unidirectional fiber composites are discussed. A variety of experimental techniques are compared, and the non-interfacial damage prevention of the specimens leads to the inaccuracy of short-beam shear tests. The test is a good test and explains the reason for the failure of the transverse interface. By testing the two composites, the two technologies were compared. The results show that the damage energy of different interface properties can be detected flexibly by the transverse tensile test.
