摘要： This invention relates to a process for manufacturing a piece of composite material made with a polymer resin and fiber reinforcement from at least two subcomponents comprising the following steps: a) providing the first subcomponent partially cured in a curing cycle in an autoclave at a maximum temperature T1, comprised between the resin gelling temperature GT and the resin curing temperature CT, applied for a predetermined time PT1 such that the exothermal component is released from the first subcomponent in a degree exceeding 50%; b) providing the second subcomponent in a fresh or cured state; c) assembling the two subcomponents and then joining them to one another in a curing cycle in an autoclave at a maximum temperature T2 comprised between 90% and 100% of the resin curing temperature CT, applied for a predetermined time PT2.

摘要： A process for manufacturing stiffened structures (11) in composite materials formed by an outer skin (13) and a plurality of stiffeners or stringers (15) the cross-section of which has a closed form delimiting an inner opening (23), comprising the following steps: a) Providing a shaping tool (31); b) Providing auxiliary male tools (37) of a material capable of varying its volume due to the effect of temperature and/or pressure, covered with membranes suitable for curing c) Providing stiffeners or stringers (15); d) Arranging the stiffeners or stringers (15) in the tool (31) and the auxiliary male tools (37) in their inner openings (23); e) Laminating the outer skin (13); f) Curing the stiffened structure (11) with high temperature and pressure; g) Removing the auxiliary male tools (37) after reducing their volume; h) Separating the cured stiffened structure (11) from the tool (31). The invention also relates to the auxiliary male tools.
