METHOD FOR PRODUCING A STRUCTURE MADE OF COMPOSITE MATERIAL FOR RAILWAY VEHICLES

摘要

The invention concerns a method for producing a structure made of composite material for railway vehicles. The invention is characterised in that it consists in: producing a framework (1) preferably consisting of two half-frames (2, 2'); fixing panels (3) made of open-cell foam or the like between the posts of said framework; producing a filament winding of fibres and resin on a mandrel (4) having a clearance adapted to said framework and a longitudinal reinforcement by fabric deposit so as to produce a first skin (5) covering said mandrel; positioning the framework (1) on said first skin of the mandrel (4); producing a second skin (8) covering the structure obtained by filament winding of fibres and resin and longitudinal fabric deposit on the panels (3) of said framework; heat-curing; cutting off the ends of the structure; and withdrawing said mandrel.
