Abstract

The present invention relates to composite material preparing technology, and is especially preparation process of continuous SiC fiber reinforced Ti alloy-based composite material. The prefabricated band prepared through mixing polyestyrene as adhesive, xylene as solvent and Ti alloy powder, and the fiber cloth made through continuously twisting SiC fiber are deaired, heated and hot pressed to obtain composite material plate. The present invention provides the practical technological path for preparing SiC fiber reinforced Ti alloy-based composite material in low cost, and the composite material may prepared with cheap alloy powder and polystyrene as adhesive in simple apparatus. The preparation process has no pollution, and is simple, practical and wide in application.

Description

technical field

[0001] The invention relates to composite material preparation technology, in particular to a method for preparing continuous SiC fiber reinforced Ti alloy matrix composite material. Background technique

[0002] With the development of aviation, aerospace and space technology, the use environment of aircraft materials is more harsh and harsh, and the resulting force, heat, chemical and physical effects are concentrated on the structural materials that make up aircraft and engines, which has great impact on Lightweight, high strength, high toughness, heat resistance, fatigue resistance, oxidation resistance and corrosion resistance of materials also put forward more stringent requirements. At present, the development of traditional high-temperature Ti alloys has almost reached its limit, but the brittleness and formability of Ti-Al intermetallic compounds limit its popularization and application. SiC continuous fiber reinforced titanium alloy matrix composit...
