Title: Development of high and ultra-high temperature ceramic matrix composites

Biography

Abstract

There is an increasing demand for advanced materials for aerospace and other applications, with temperature capability ranging from 1500â„ƒ to well over 2000â„ƒ and able to survive highly corrosive environments whilst subject to intense heat fluxes and mechanical stresses. The interaction of environmental conditions together with the requirement that dimensional stability is maintained makes the selection of suitable materials extremely challenging. This paper discusses the design, development, manufacture and testing of a new class of ceramic matrix composites based on either SiC or C fibre preforms and enriched with different ceramic powders as well as a matrix infiltrated by either microwave- or RF-heated chemical vapour infiltration (CVI). These composites will form suite of materials suitable for application in severe aerospace environments.
