Process for the curing with ionizing rays of a bismaleinimide resin and a composite material from this resin.

摘要

The process for curing according to the invention a base resin A comprising at least one bismaleimide monomer consists in adding to the base resin A, before it is used, at least one reactive diluent B consisting of a monomer containing a vinyl end copolymerisable with the base resin A when a mixture of the base resin A and of the diluent B is subjected to an ionising radiation (34), the total quantity of diluent B being such that the maleimide functional groups of the base resin A are consumed after the action of the ionising radiation and being chosen within the range of 10 to 50 parts by weight per 100 parts by weight of the base resin A. This resin is intended in particular for the production of a composite material (16, 18) with a fibrous reinforcement (26, 28, 30, 32) using filament winding. <IMAGE>
