Trihedral junction piece for secondary structure of fuselage of aircraft, has connection surfaces formed between its operating surfaces, where piece consists of composite material with continual fiber reinforcement to resist fire and smoke

摘要

The piece (20.b) has continuous connection surfaces without opening (230) formed between its operating surfaces (210, 211, 220), where the piece consists of a composite material with continual fiber reinforcement to resist fire and smoke and is manufactured by stamping a composite blank with strengthened thermoplastic matrix. Thickness variation of the operating surfaces on an assembly of the piece is less than 0.05 millimeter. Independent claims are also included for the following: (1) a stamping method for producing a trihedral junction piece (2) a device for implementing the stamping method for producing a trihedral junction piece.
