Finite Element Analysis of Microscopic Behaviors of SiC/SiC Composites : Effects of Porosity and Sin Waved Fiber

Ceramic matrix composites based on silicon carbide (SiC) matrix offer high strength, toughness and oxidative stability up to 1200°C. However there are many cases in which it is difficult to evaluate stiffness and stress of SiC/SiC composites because of material's microscopic factors. Therefore,...

Zusammenfassung:Ceramic matrix composites based on silicon carbide (SiC) matrix offer high strength, toughness and oxidative stability up to 1200°C. However there are many cases in which it is difficult to evaluate stiffness and stress of SiC/SiC composites because of material's microscopic factors. Therefore, in this paper, (1) the relationship between stiffness and porosity were estimated by a Monte-Carlo simulation technique based on a finite element method. Results approximated to the equation of Wagh et al. (2) The effect of sin waved fiber was analyzed. Microscopic-scale stress distribution was investigated.
