Abstract
A method for making in a single step a multiple-ply panel comprising the steps of forming and sandwiching a raw mat assembly of resinated furnish between two sheets of green incised wood veneer, applying a layer of thermosetting high-moisture tolerant adhesive at interfaces between the green veneer and core mat, and applying pressure and heat to cure the consolidated panel assembly for a duration sufficient to secure good internal bond within the substrate panel.

A method for making a multiple-ply panel wood composite comprising the steps of:
- (i) forming a panel substrate by sandwiching a resinated mat between two sheets of green incised wood veneer;
- (ii) applying a thermosetting and moisture compatible adhesive between the veneer sheets and the resinated mat to form an unconsolidated panel;
- (iii) applying pressure and heat to the unconsolidated panel in an amount and for a duration sufficient to cure the resin and the adhesive, to form said composite panel.
