低成本PIP工艺制备陶瓷基复合材料研究进展

Research Development on Low-Cost Ceramic-Matrix Composites by Polymer Infiltration Pyrolysis

聚合物浸渍裂解(Polymer infiltration pyrolysis,PIP)工艺简单,可以净尺寸成型复杂构件,在陶瓷基复合材料制备中有着广泛的应用。但是其先驱体合成工艺复杂、陶瓷产率低、价格昂贵,且PIP工艺周期长,使得生产成本高昂,影响其发展和工程化应用。从陶瓷先驱体的低成本研发与高效率的致密化工艺两部分对陶瓷基复合材料的低成本制造进行了综述。

Polymer infiltration pyrolysis(PIP)is widely used in the preparation of ceramic matrix composite because of its simple process,and being adopted to mold complex components in clear dimension.However,its precursor has complicated synthetic process,with low ceramic yield,high price,resulting in the long producing cycle and high cost of PIP,which handicaps the development and engineering application of PIP.This paper reviews the low-cost production of ceramic matrix composite from two perspectives:The low-cost research and development of ceramic precursor,and the efficient densification process.
