MAGNETICALLY LOADED COMPOSITE ROTORS AND METHOD OF MAKING A MAGNETICALLY LOADED PRE-IMPREGNATED TAPE |
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 a pre-impregnated tape 8. The pre-impregnated tape is fed to a heating station where it is bonded with a thermoplastic resin impregnated fibre tow to produce a magnetically loaded composite tape. The heating station includes a rotatably driven heated mandrel (20) having a magnetic field (41, 42) embedded therein to provide the pre-impregnated tape (8) with a desired magnetic configuration. |
