Elevated Temperature Behavior of Glass and Ceramic Matrix Composites
Abstract
This research effort can be categorized into three major areas. Section 1 of the report summarizes research on continuous fiber reinforced ceramic matrix composites. A systematic investigation of the damage development and failure behavior of Nicalon silicon carbide fiber reinforced calcium aluminosilicate composites was first conducted through mechanical testing and microscopy. Then, an analytical effort was made to examine the fracture behavior and thermal shock resistance of continuous fiber reinforced ceramic matrix composites. Section 2 is on whisker and/or short fiber reinforced ceramic matrix composites. The effort included analytical modeling of crack deflection and creep behavior of whisker reinforced composites, characterization of fracture mechanisms in whisker/short fiber ceramic composites at elevated temperatures, and experimental investigation of high temperature creep behavior of the SiC(w)/ A/2O3 composite system. Section 3 is on processing. Two research efforts have been reported. In one, the kinetics of the chemical vapor infiltration (CVI) process for fabricating continuous fiber reinforced ceramic composites was modelled for both isothermal and forced CVI conditions. In the other effort, sol-gel processing route was used to develop three-dimensionally reinforced textile (woven and braided) ceramic composites.
