Connecting method of ceramic-base composite

Abstract

A method for linking two members made of ceramic-based composition includes such steps as making a rivet with ceramic-based composition, drilling hole on said members A and B, linking them together by inserting said rivet in said holes on members A and B, depositing silicon carbide in the gap by CVD, trimming, removing excessive rivet, smoothing surface, and preparing silicon carbide coating.

Description

Technical field [0001] The invention relates to a method for connecting composite materials, particularly a method for connecting carbon-based and silicon carbide ceramic-based composite materials, which is mainly suitable for the connection of ceramic-based composite material components with large complex thin walls and high dimensional accuracy requirements. Background technique [0002] Ceramic matrix composites are a new generation of strategic thermal structural materials that replace metals. The outstanding advantages are high temperature resistance and low density, and they have broad application prospects in aviation, aerospace, aerospace and weapons. With the increasing demand for large and complex thin-walled ceramic matrix composite components, connection has become a key technology that limits its application. Ceramic matrix composites mainly have three toughening methods: continuous fiber, whisker and particle toughening, and continuous fiber toughening has multiple ...
