The invention relates to a component having at least to some extent a layer structure, wherein the layer structure includes an elastomer layer with a density greater than 800 g/L, and a thermoset layer including at least 50% by weight of a first polyurethane. The invention further relates to a process for the production of a component of this type, the process including (i) provision of a female mold into which the individual layers of the layer structure are introduced, or of a male mold to which the individual layers of the layer structure are applied; (ii) production of the elastomer layer via spraying; (iii) production of the thermoset layer via spraying; and (iv) demolding of the resultant component. Step (ii) can be carried out before step (iii) or step (iii) can be carried out before step (ii).

Component composed at least to some extent of a layer structure and process for production thereof

The invention relates to a composite material having two or more superimposed wood layers. Said layers are joined together by means of a one component polyurethane adhesive containing a prepolymer having free NCO groups and a wood having a volume fraction of libriform fibres in the region of between 50-70% is used.

Composite material comprising two or more superimposed layers of woods

The invention relates to the use of a composite material having two or more superimposed layers of wood as a support element in structural engineering, nautical, vehicle and aircraft constructions, energy production systems, mining or in the production of furniture. The wood layers are joined together by means of a one component polyurethane adhesive containing a prepolymer with free NCO groups and the wood has a structure having a volume fraction of libriform fibers of between 50%-70%.
