Abstract
The invention concerns three-layer composites with their plastic core so uniformly enriched with an appropriate percentage by volume of a ferrosilicon with an appropriate particle size that the composites can be securely joined to each other and to sheets of metal alone by resistance welding. The property applies to composites with either a viscously elastic or an impact-resistant core.
