Strukturelement aus einem faserverstärkten thermoplastischen Material und Verfahren zu seiner Herstellung

摘要

A structural member of fiber reinforced composite material suitable for secondary processing and a method of processing is described. The structural member (14) before secondary processing is typically a multi-ply tube, rod, or sheet formed with an outer sheath (13) of fiber reinforced thermoplastic material having a melting temperature tm1 and an inner core material (12), also fiber reinforced thermoplastic, having a melting temperature, tm2 lower than tm1. The member, prior to secondary processing, is thermoplastic. In a secondary process the member is heated to a temperature between tm1 and tm2, but sufficient to render the outer sheath malleable. The member is deformed to a desired geometry, such as a helix, and cooled to a hardened state.
