发明名称 METHOD FOR PRODUCING A PROFILE THAT HAS A RE-ENTRANT ANGLE IN A COMPOSITE MATERIAL FROM A STACK OF LAYERS OF FIBRES
摘要 A method for producing, in a composite material, a component that has a re-entrant angle, includes stacking layers of fibres which have been pre-impregnated with a resin so as to obtain a preform and placing the preform in a tooling fixture in order to subject it to a polymerization cycle including a temperature cycle, with a temperature-increase phase and at least one soak at which the temperature is maintained, and a pressure cycle on the outside of the tooling fixture with a pressure-increase phase and a pressure-hold phase, with the layers of pre-impregnated fibres being able to slip against one another when the temperature of the temperature cycle is equal to or higher than a threshold temperature Tf dependent on the resin. The temperature-increase phase includes a soak at a temperature higher than or equal to Tf, the soak beginning before the end of the pressure-increase phase.
