Research on the composite curling characteristic of plastic film reinforced pliable veneer of teak

Abstract

In order to study the curling deformation characteristic of plastic film reinforced pliable decorative sliced veneers of teak (teak PRPDSV for short, a kind of green product with mechanical meshing structure by the permeation of plastic film into the pliable decorative sliced veneer through high-temperature hot pressing and fusion), which is unlike other veneer species, this paper established a constitutive model between reinforcing plastic films and veneers under different temperatures on the basis of stress-strain testing. Different hot-press temperatures and material thickness have been applied in the model to verify the experimentally obtained curling degrees of a teak PRPDSV. The study results show that: curling deformations obtained in the elastoplastic mechanical model, into which a material stress-strain curve has been introduced, for a plastic film and a teak veneer through high temperature hot-press composite processing, is highly accurate and scientific, and the model is up to be used for prediction in practical production; the material’s thickness are quite different against other decorative veneer species.
