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.
Claims24
A composite material having a three-dimensional contour, comprising:
- a first outer covering layer;
- a second outer covering layer disposed at a spacing distance from said first outer covering layer;
- an intermediate layer arranged between said first and second outer covering layers and formed by at least one natural fiber mat of renewable raw materials and interspersed with bonding material components selected from the group consisting of fusible particles, foamable particles, and curable substances, said bonding material components bonding fibers of said at least one natural fiber mat to one another and adhesively bonding materials of said first and second outer covering layers;
- and
- said spacing distance between said first and second outer covering layers being approximately inversely proportional to a degree of compaction of said intermediate layer.
