摘要
采用拉伸蠕变试验方法研究了树脂基三维编织复合材料的蠕变性能,分析了编织结构、编织角和纤维体积含量对三维编织复合材料蠕变性能的影响.实验结果表明:在本文试验条件下,树脂基三维复合材料的蠕变曲线分为减速和恒速两个阶段;三维编织复合材料的抗蠕变性能随编织角的减小、纤维体积含量的增加而提高,且三维五向结构的抗蠕变性能优于三维四向结构的抗蠕变性能.
The creep behavior of resin-based 3-D braided composites is studied by using the tensile creep test method, and the influencing factors including braiding structure, braiding angles and fiber volume fractions are discussed. In the test condition, the creep curve of 3-D braided composites comprises two phases, which are the deceleration phase and constant acceleration phase. The experiment results show that the creep resistant properties are improved while the braiding angle decreases or the fiber volume fraction increases, and that the three-dimensional five-directional braiding structure offers better creep resistant properties than the three-dimensional four-directional braiding structure.
