摘要/Abstract

摘要： 采用碳纤维/玻璃纤维层内混杂单向布,设计了5种不同混杂结构和5种不同混杂比的试件,研究了混杂结构、混杂比对碳纤维/玻璃纤维面内混杂复合材料0°拉伸破坏模式的影响,建立了各自的拉伸破坏模式。结果表明:①相同混杂比、不同混杂结构试件的破坏模式可归结为3类,在进行相同混杂比、不同混杂结构设计时要避免使用两半式结构;②相同混杂结构、不同混杂比试件的拉伸断裂应力和应变的变化趋势相反,其破坏模式可归结为两类。此种情况下,碳纤维/玻璃纤维混杂比控制在3:2左右时拉伸性能较好。

Abstract: This article uses carbon fiber/glass fiber inner ply unidirectional fabrics to design specimens of 4 types of various hybrid structures and 5 types of different hybrid ratios. The influence of hybrid structure and mixed ratio on the 0° tensile failure mode of C/G inner ply hybrid composites was investigated. The failure modes are given respectively in the paper. The results show that: ①The tensile failure modes of specimens with the same mixed ratio but different hybrid structures can be summed up in three categories. When we design the specimens with the same mixed ratio but different hybrid structure, the structure like should be avoided; ②The tensile failure stress and strain have the opposite trend. The tensile failure modes of specimens with the same hybrid structure but different mixed ratios can be summed up in two categories. In this case, we can get better tensile property with the mixed ratios of C/G to be around 3:2.

Key words: carbon fiber, glass fiber, C/G inner ply hybrid, hybrid ratio, hybrid structure, tensile failure mode
