Process for the hardening, curing or setting of a bis-maleimide resin and a composite material using said resin. The setting process according to the invention of a basic resin A having at least one bis-maleimide monomer consists of adding to the basic resin A, prior to the use thereof, at least one reactive diluent B consisting of a monomer having a copolymerizable vinyl termination with the basic resin A when subjecting the mixture of the basic resin A and the diluent B to the action of ionizing radiation (34), the total quantity of the diluent B being such that the maleimide functions of the basic resin A are consumed following the ionizing radiation action and being chosen in the range 10 to 50 parts by weight for 100 parts by weight of the basic resin A. This resin is more particularly intended for the production of a composite material (16, 18) having a fibrous reinforcement (26, 28, 30, 32) by filamentary winding.
