Faserverstärktes thermoplastisches Blatt, insbesondere eines eingelassenen Heckrotors und sein Herstellungsverfahren

摘要

The blade has its lower (overpressure) face covering (6a) and top (suction) face covering (6b) of its shell, its front filling body (9) and its rear filling body (10) and its spar (7) all made of a composite material having the same thermoplastic matrix, preferably made of PEEK, preferably reinforced with carbon fibres. The spar (7) is extended outside the shell by an integrated root part having a connection attachment, in the form of a loop or laminated, in the same thermoplastic composite. The process consists in assembling, by melting under pressure, all the blade components made of thermoplastic composite, in a single operation, after manufacture of these components in the form of prefabricated elementary components.
