For the production of spliced veneers the veneers are coated with thin cellulose fleece or special paper layers, and thereby thin composites are generated. This article describes the mechanical properties of such a composite material consisting of 0.35 mm beech (Fagus sylvatica L.) veneer and a 0.12 mm cellulose fleece bonded with a PVAc adhesive.
The investigations showed that the mechanical properties of materials based on thin veneers are significantly influenced by the applied adhesive. The modulus of elasticity perpendicular to the wood fibre is considerably increased which is disadvantageous to the flexibility of the material but does have advantages for components that need to withstand high static loads.
