MAGNETICALLY LOADED COMPOSITE ROTORS AND TAPES USED IN THE PRODUCTION THEREOF

摘要

A method of making a magnetically loaded pre-impregnated tape uses a drum (1) that is heated and which is associated with a heated bath (2) containing a thermo-plastic resin solution. A fibre tape material (4) is fed onto the drum (1) and, just prior to the fibre tape material meeting the periphery of the drum, the fibre tape material (4) is impregnated with an isotropic magnetic particle material (6) to form the pre-impregnated tape (8). The pre-impregnated tape may be fed to a heating station where it is bonded with a thermoplastic resin impregnated fibre tow to produce a magnetically loaded composite tape.
