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.

Resistance-weldable composite

To extend the temperature range of composite materials the composite material is made up of more than two hard layers which are joined with thin intermediate layers of viscoelastic material where one intermediate layer differs from another intermediate layer in that its softening range lies in a different temperature range so that the damping ranges of the intermediate layers also are different.
