Influence of Carbon Cloth Filaments upon the Properties of 2D C/SiC via Precursor Infiltration and Pyrolysis Process

摘要：

　　In this paper,2D C/SiC composites with different carbon cloth filaments (1K,3K) were prepared via precursor infiltration and pyrolysis (PIP) process.The flexural strength of 2D-1K C/SiC composites was 380MPa,and fracture toughness was 16.8MPa-m1/2,while those of 2D-3K C/SiC were 305MPa and 14.4MPa-m1/2,respectively.The differences of these two composites were analyzed from fiber volume ratio in the composites,density,and fracture surface (SEM) of the samples.
