Abstract
A growing tendency exists for the use of wood and resin-impregnated cloth or paper, which is an outgrowth of laminated - plywood developments. Combinations of cloth and paper with wood, in addition to serving as vehicles for the bonding glue in the manufacture of the laminates, also help stabilize the wood assemblies and provide structural advantages, as demonstrated by test data given in the paper. For example, when a reasonably large number of paper laminates are used, there is an apparent increase in the tensile properties of wood, attributable to prestressing of the wood resulting from differences in coefficients of thermal contraction as parts are cooled upon removal from the press. Dimensional stability in plywood faced with phenolic-resin-treated cloth and paper is found to be far superior to unprotected plywood.
