PIP法制备SiC纳米线增强SiCf/SiC复合材料及其力学性能
Effect of SiC Nanowires on Mechanical Properties of PIP-SiCf/SiC Composites
摘要
Abstract
Two–dimensional SiCf/SiC composites were preparedvia in-situ growth of SiC nanowires on the matrix of SiC fabric by a chemical vapor deposition (CVD). The effects of SiC nanowires and pyrocarbon (PyC) layer between SiC nanowires and SiC matrix on the mechanical properties of composite, crack propagation behavior, and interfacial bonding strength between the fiber and matrix were investigated. The results show that, the introduction of SiC nanowires can improve the densification significantly, enhance the interfacial bonding strength between the fiber and matrix, and modulate the fracture mode of the matrix in brittle area as well. Besides, PyC layer can moderate the interfacial bonding strength and affect the mechanical properties.关键词
