PROCESS OF MANUFACTURE OF A THERMOSETTING COMPOSITE PART COVERED WITH A THERMOPLASTIC LAYER

摘要

The invention relates to a process for manufacturing a part (111) made of a composite material, said process comprising the following steps: a step of depositing one or more structural plies (12, 13) impregnated with a thermosetting resin (15) in order to form a structural layer, a step of depositing a surface layer as a stack with the structural plies, said surface layer being formed from an assembly (117) of one or more fibres (118) of thermoplastic resin, said assembly being deformable in at least two directions, said thermoplastic resin having a melting temperature close to a polymerization temperature of said thermosetting resin, then, a step of polymerization of the structural layer at the polymerization temperature, the surface layer then taking the shape of a continuous film that coats the structural layer. Said surface layer may ensure the drainage of air during the polymerization step.
