Structure of Coreless, Long Silicon Carbide Fibres and Aluminum—SiC Composites

Using electron microscopic, x-ray, and sorption methods, the internal structure, surface, and porosity of coreless silicon carbide fibres and composites were investigated. A model of the interaction at the aluminum melt —SiC fibre interface was proposed. The effect of low-temperature annealing on the structure and properties of domestic and Japanese coreless silicon carbide fibres was observed. The reaction rate in composites reinforced with domestic annealed fibres decreased.
