A method for the production of complex hollow bodies by uniaxial hot pressing of a composite material with a glassy matrix and the products thus obtained

摘要

The process consists in introducing a quantity of material (3, 4) which is necessary and sufficient to obtain the final composite into a volume (1) defined by the walls of a mould (2), in placing into the material removable inserts (5) which correspond to the hollow regions of the final article, in applying a uniformly distributed mechanical pressure (P) to the whole with heating, in removing the combination of article and inserts (3, 4, 5) from the mould and in mechanically withdrawing the removable inserts (5). Application of structural articles made up of sandwich panels incorporating an internal stiffener.
