Procedure for the manufacture of large parts by lamination, vacuum and pressure

摘要

Procedure for the manufacture of large parts by lamination, vacuum and pressure in which the fabric, after impregnation, is subjected to a vacuum in a closed medium in order to absorb the surplus resin and when once more under pressure it is positioned on a half-mould to the external surface of which a vacuum pump is applied, a pneumatic casing being placed over the assembly, and then the mould is closed so that applying pressure to the casing results in perfect adaptation to the walls of the mould so that heat can then be applied to it from a mobile oven situated nearby.
