Abstract (en)
[origin: JPH0586534A] PURPOSE: To obtain a densified fibrous preform easily by forming a fibrous preform with a parallel and specific discontinuous fiber and a covering yarn, and then releasing a binding of the discontinuous fiber in a preform volume by eliminating the covering yarn. CONSTITUTION: A preform is obtained by uniting a discontinuous fiber group disposed parallel to one another without twist and made of carbon fibers, refractory fibers of ceramic fibers or its precursor with a covering yarn made of a soluble polymer of the discontinuous fiber group having denier less than 1/10, forming thus obtained yarn into a two dimensional fiber structure by weaving, eliminating the covering yarn in a bath of for example 80 deg.C, and treating several layers by needle punching.
Abstract (fr)
Une préforme fibreuse est fabriquée au moyen d'un fil formé de fibres longues discontinues en matière réfractaire ou en un précurseur de celle-ci, les fibres étant arrangées parallèlement les unes aux autres, en étant non retordues, et l'intégrité du fil est assurée par guipage au moyen d'un fil en matière fugitive. Une pièce en matériau composite est réalisée par densification de la préforme fibreuse après élimination du fil de guipage.
