| 摘要 |
<p>The present invention is an article comprising a fiber-reinforced engineering thermoplastic polyurethane composite (12) welded to a thermoplastic part (5) by way of an interlayer (7) containing a dispersion of a ferromagnetic material (8) and a method for preparing the same. Alternatively, the composite (12) or the thermoplastic part (5) or both may contain the ferromagnetic material (8). A tight bond is created by subjecting the ferromagnetic material to a radio-frequency magnetic field to generate heat, which locally melts composite (12) and the thermoplastic part (5), then allowing the subjected areas to cool. The invention is particularly useful for the preparation of window frames.</p> |
