摘要
使用不同编织方式制备了三种SiC纤维预制体(二维编织,2.5维编织和三维五向编织),采用树脂转移模塑(RTM)和聚合物浸渍裂解(PIP)工艺制备了SiC f/PyC/SiB CN复合材料。观察了复合材料的显微组织,测试了弯曲强度、拉伸强度、压缩强度等力学性能,探究了不同编织方式对复合材料力学性能的影响行为。结果表明,同一编织方式在不同方向的纤维分布不同导致了材料力学性能的各向异性,编织方式对材料力学性能有着显著的影响。
Three continuous silicon carbide fiber reinforced SiB CN composites(SiC f/PyC /SiB CN), being distinguished by different weaving methods of fibers(including two dimensional woven, 2.5 dimensional woven and three dimensional five directional woven), were fabricated by resin transfer molding(RTM) and polymer impregnation & pyrolysis(PIP) technology. In order to study the impact of waving methods, the microstructures of fabricated composites were observed and the mechanical properties such as tensile & compression strength or bending strength of the composites were tested. The results show that different distributions of fibers on different directions lead to anisotropy of mechanical properties for each composite, and waving method has a significant influence on the mechanical properties of the composites.
