Ceramic Matrix Composites by Liquid Infiltration

Abstract

This work was done in response to a well recognized need for a more effective process for manufacturing advanced ceramic matrix composites. It is based on a proposal by Applied Sciences, Inc. and the Basic Industry Research Laboratory (BIRL) of Northwestern University to evaluate the feasibility of a new, unique Liquid Infiltration process for depositing ceramic matrix materials within woven fiber preforms. This process consists of uniformly infiltrating the perform with a concentrated solution of a precursor in a low viscosity solvent, evaporation of the solvent, introduction of a gaseous second precursor which forms a solid adduct with the first precursor, and then pyrolyzing the adduct to the desired matrix material.
