摘要:
In order to produce a part (16) from a composite material, which is conductive at least on one of the surfaces thereof, the method consists of: the conductive overstitching (30) of a preform (20) of the part using electrically or thermally conductive threads (31, 32) with substantially parallel stitch lines (34) oriented in at least two intersecting directions. The parts obtained are adapted for the production of aircraft structures that may be subjected to lightning strikes and allow return currents from the electrical or electronic aircraft equipment and/or the discharge of heat by conduction.

摘要:
To produce a complex structure made of a composite, with assembled individual parts, a method includes the steps of: producing individual parts; producing assembly components, to ensure structural bonds between the individual parts, from fibers impregnated with a resin capable of curing by polymerization, comprising fins attached to a core that determine grooves, in order to receive edges, of the individual parts, subjected to a partial thermal cure to partially polymerize the resin and give the components a dimensional stability and thermoplastic properties; positioning of the individual parts and assembly components; raising the temperature to a thermoplastic forming temperature and applying pressure P in order to apply the fins to faces of the individual parts; and carrying out a complete thermal cure for polymerization of the resin of the assembly components.
