Continuous fiber reinforced ceramic composites†

Abstract

The pertinent issues of woven fiber fabric reinforced ceramic composites, such as processing, interface engineering, mechanical behavior, and theoretical modeling, have been discussed. The continuous plain‐weave Nicalon® fiber reinforced SiC composites have been successfully manufactured by a novel forced chemical vapor infiltration (FCVI) method. The FCVI technique can be modeled using a finite‐volume method to optimize the processing conditions, resulting in the savings of fabrication time and cost. Fiber fabric orientation and interface coating greatly influenced the mechanical behavior of the composites. Theoretical modeling is conducted to investigate the influence of fiber fabric orientation and coating thickness on the mechanical behavior of woven fabric reinforced composites. The predicted results were in good agreement with the experimental data.
