Abstract
A method for manufacturing a fiber preform including a number of plies greater than or equal to two, includes: a) heating a ply; b) depositing the ply on a preforming mold; c) forming the ply, the ply then forming an intermediate preform; d) heating a new ply; e) depositing the new heated ply on the intermediate preform; f) forming the new ply in order to form a new intermediate preform; g) where applicable, repeating steps d) to f) at least once, the intermediate preform being replaced in these steps by the new intermediate preform in order to produce the fiber preform with the number of plies.
Claims16
A method for manufacturing a fibrous preform comprising a predetermined number of plies greater than or equal to two, comprising the following steps:
- a) heating at least one ply,
- b) depositing said at least one ply on a preforming mold,
- c) performing an operation of forming of said at least one ply, said at least one ply then forming an intermediate preform,
- d) heating at least one new ply,
- e) depositing said at least one heated new ply on the intermediate preform,
- f) performing an operation of forming of said at least one new ply so as to form a new intermediate preform,
- g) possibly repeating, at least once, the steps d) to f), the intermediate preform being replaced in these steps by the new intermediate preform, so as to produce the fibrous preform with said predetermined number of plies.
