Grinding Effect of C/C-SiC Composites Prepared by Isothermal Chemical Vapour Infiltration during Braking Process

چکیده
A kind of 2.5-dimensional C/C-SiC composites was fabricated by using Isothermal Chemical Vapour Infiltration process (ICVI). Frictional properties of this material were evaluated by using MM-1000 under dry condition. Average dynamic friction coefficient of it was 0.16, static friction coefficient and average coefficient stability were 0.15 and 0.56, respectively. However, weight wear rate was less than 1.25 mg·time-1. Moreover, friction surface with low roughness has been observed. Then, the “Grinding Effect” has been presented, which will decrease surface roughness. The “Grinding Effect” was a kind of abrasive wear, which was mainly due to high superficial hardness.

Ceramic matrix composites (CMCs) is one of the most promising candidates for high temperature structural material, in which SiC matrix exhibits an excellent oxidation resistance because of the formation of a protective layer of silica which limits further oxidation [1]. CMCs with continuous fibers exhibit attractive properties such as low densities, high elastic moduli, and high strengths at el...

This paper presents an experimental design approach to the process parameter optimization for compocasting of A356-SiCp composites. Toward this end, parameters of stirring temperature, stirring time, stirring speed and SiC content were chosen and three levels of these parameters were considered. The D-optimal design of experiment (DODE) was employed for experimental design and analysis of resul...
