Influence of Carbon Fiber Treatment on Flexural Properties of C/SiC Composites

Abstract:

The purpose of this study was to investigate the influence of carbon fiber treatment on flexural properties of carbon fiber reinforced SiC matrix (C/SiC) composites. C/SiC composites were prepared by polymer impregnation pyrolysis (PIP) progress with polycarbosilane (PCS) as impregnant and carbon fiber as reinforcement. The flexural strength at room temperature of the 2D laminated composites were measured and analyzed with different carbon fiber treatment process. It was found that the flexural strength of the composites with carbon fibers coated by pyrolytic carbon was 53.5% higher than that with non-coated carbon fibers. The results also show that the flexural strength of the composites with 1600°C heat treated carbon fibers increased by 25.4% compared with the composites with non-heat treated fibers.
