Abstract

Samples of a composite material were obtained by pressure infiltration with AL2 melt of a carbon tape. Products of interaction forming on the fibre-matrix interfacial boundary were investigated. It has been found that Al4C3 and SiC phases and silicon crystals are formed. An increase of the contact time between a fibre and the melt, and melt temperature and the infiltration pressure leads an increase in the Al4C3 carbide phase quantity and to the bond strength on the fibre-matrix interfacial boundary. Here with tensile strength tests, the character of fractures changes from tensile (with noticeable fibre pull-out from the matrix) — to ductile; shear strength is increased.
