Recent work in the IRC in Materials Processing in collaboration with Rolls-Royce and others, aimed at developing low cost Oxide/Oxide CIVIC materials, has resulted in the development of a proven fabrication route with complex shape capability. Material properties are internationally competitive and manufacturing costs comparable with conventional metallic alloys. Although this material has excellent tensile properties (near theoretical) in unidirectional 'mini-composite' form (700 MPa) there are issues with variability in larger 2D fabric based CMCs. Novel matrix precursor chemistry, will be used to develop matrix precursors with optimised rheology for infiltration and lamination. Control of the processing parameters and identification of potentially automated stages will improve reliability and repeatability. Pressclave and autoclave techniques (well known in the polymer matrix composite field) will be used to fabricate both flat plates and complex shapes. A comprehensive mechanical testing programme will address tensile, low cycle fatigue and creep behaviour at temperatures up to 1200 deg.C. Particular attention will be paid to the factors controlling the development of comparable properties in both flat coupons and complex components. Microstuctural analysis of damage accumulation ( including 'in-situ' loading in a FEG SEM) will be correlated with quantitative mechanical behaviour and the data used to develop an understanding of the specific strength controlling factors associated with composition and processing. Rig test data from components will be used validate behavioural models developed in the study.
