Abstract

A method of making a magnetically loaded pre-impregnated tape uses a drumthat is heated and which is associated with a heated bathcontaining a thermoplastic resin solution. A fiber tape materialis fed onto the drumand, just prior to the fiber tape material meeting the periphery of the drum, the fiber tape materialis impregnated with an isotropic magnetic particle materialto form a pre-impregnated tape. The pre-impregnated tape is fed to a heating station where it is bonded with a thermoplastic resin impregnated fiber tow to produce a magnetically loaded composite tape. The heating station includes a rotatably driven heated mandrel () having a magnetic field () embedded therein to provide the pre-impregnated tape () with a desired magnetic configuration.
