Abstract
Nicalon plain-weave fiber fabric-reinforced SiC matrix composites have been fabricated by novel forced chemical vapor infiltration (FCVI) techniques. The influence of the fiber/matrix interface coating thickness on the fracture behavior of continuous fiber-reinforced SiC composites has been investigated. Experimental results indicate that fiber coating thickness significantly alters the fracture behavior of SiC composites. The fracture strength exhibits a maximum as the coating thickness increases. A mechanistic understanding of the fracture behavior is provided. Furthermore, a theoretical model is formulated to quantify the influence of coating thickness on fracture behavior. The predicted fracture behavior was found to be in good agreement with the experimental result.
