Abstract
The composite material can be produced without complicated measures to fix the distance between the covering layers and it can be brought into a desired three-dimensional contour. The composite material has a first outer covering layer and, at a distance from it, a second outer covering layer, in particular of metal, plastic or wood veneer. An intermediate layer is arranged between the covering layers. The intermediate layer is formed by at least one natural fiber mat of renewable raw materials which is interspersed with fusible and/or foamable particles and/or curable substances.
