Zusammenfassung:Method for producing a piece of a compound material made with a polymeric resin and a fibrous reinforcement from at least two subcomponents, which co mprises the following steps: a) Providing the first subcomponent, partially cured in an autoclave curing cycle at a maximum temperature T1, between the gel temperature TG of the resin and the curing temperature TC of the resin, applied for a predetermined time TP1 such that the exothermic component of t he first subcomponent is released to a degree above 50%; b) Providing the se cond subcomponent, in the fresh or cured state; c) Assembling the two subcom ponents and joining them in an autoclave curing cycle at a maximum temperatu re T2 of between 90% and 100% of the resin curing temperature TC, applied fo r a predetermined time TP2.
