Technical Examples
  1. A method of forming a composite article is disclosed that involves providing a press having first and second platens, a cellulosic fiber substrate having a first thickness, and a layer of material such as a wood veneer, foil, or non-creped paper, where the layer of material has a thickness less than the thickness of the cellulosic fiber substrate. A layer of bonding material is placed onto the cellulosic fiber substrate or the layer of material, and the layer of material is placed onto the cellulosic fiber substrate so that the bonding material is between the layer of material and the cellulosic fiber substrate. The cellulosic fiber substrate and layer of material are placed between the first and second platens, and at least one of the first and second platens is moved toward the other of the first and second platens to deform the cellulosic fiber substrate and layer of material into a predetermined configuration while bonding the layer of material to the cellulosic fiber substrate without cracking or wrinkling the layer of material.
