OPEN THREE-DIMENSIONAL STRUCTURE WITH HIGH MECHANICAL RESISTANCE

摘要

The invention relates to a method for making an open three-dimensional structure made of an inorganic material, in particular carbide, said method comprising: (a) providing a preform made of woven fibres that includes two substantially parallel planes each defining meshes, and each pair formed by two adjacent planes being coupled together by connecting yarns or fibres preferably made of the same material as the woven cellular planes; (b) depositing on the preform a precursor of an inorganic or carbon material by a liquid or gaseous process; (c) carrying out a heat treatment for converting said inorganic or carbon material precursor into a part respectively made of an inorganic or carbon material.
