摘要: Abstract In order to improve the mechanical properties of CBCFCs, CBCFCs with in-situ grown SiC nanowires (SiCNW) were fabricated based on chemical vapor reaction process and precursor impregnation pyrolysis (PIP) process. The effect multi-scaled reinforcements (micro-scaled carbon fibers nano-scaled SiCNW) was investigated. phase, microstructure fracture surface composites characterized by XRD, SEM TEM. Microstructure characterization found that SiCNW randomly distributed in matrix formed a network structure CBCFCs. can significantly More importantly, orientation anisotropy is also obviously deceased due SiCNW. improved decreased could be attributed pull-out bridging SiCNW, which reinforcements.
