Filament winding of a model system of SiC{sub fibre}Si{sub 3}N{sub 4} has been studied with regard to the microstructure. Processing parameters such as speed, fibre roving tension and spacing, together with slurry properties have been varied. Fibre rovings were completely impregnated in the immersion step but voids formed in the winding step. Fewer voids formed for the water-based slurries compared with slurries with petroleum spirit. Layered structures were formed when a low winding speed was used as the surface dried before the next roving was applied. This type of inhomogeneity can be quantified using image analysis.
