Abstract

The invention relates to a preparation method for making unit doublet carbide codeposition fiber reinforcement composite material through chemical gas phase permeation / deposition process, wherein, codeposition unit doublet carbide is obtained inside a preformed billet body made of C fiber, boron fiber, ceramic fiber and metal fiber, etc. by use of the designability of chemical gas phase permeation / deposition process to make fiber-reinforcement unit doublet carbide composite material; the carbide is the combination of any two sorts of carbide of HfC, TaC, ZrC, NbC, WC, TiC, B4C, VC, AlC and SiC, etc. The material made through the method is characterized by high temperature resistance, wear resistance, anti scour, antioxidation, ablation resistance and excellent thermal shock resistance.

Description

Manufacturing method of binary carbide co-deposition fiber reinforced composite material Technical field: Technical field: The present invention relates to a chemical vapor infiltration / deposition process for manufacturing binary carbide co-deposited fiber-reinforced composite materials, which are mainly used for functional structural components that require high temperature, high hardness, oxidation resistance, and ablation resistance. Background technique: Background technology: chemical vapor deposition chemically synthesizes materials at the atomic and molecular levels, so materials can be designed and prepared at the nanometer level; the preparation process can ensure the controllability and reproducibility of composition and structure; material preparation and device manufacturing have the same Sex; the equipment is relatively simple, easy to operate, and easy to realize automatic control. Another advantage of preparing materials by chemical vapor deposition is that ...
