Abstract
This thesis presents results on methods used to produce a hard surfaced wood product. The methods involve the parting of the wood fibers on the surface by a special serrating tool, followed by surface impregnation and final curing. The serrations on the wood surface produce an artificial grain upon curing. A preliminary investigation was made to improve the rot-resistance of wood by gaseous treatment. Results of such treatments show some limited success with formaldehyde on yellow poplar and warrant further study. An investigation was made to find a substitute for teak wood used on submarine decking. A number of combinations of woods and impregnating agents were prepared and tested under simulated ocean conditions. The results of those tests indicate that a maple-mahogany laminate, when treated with the proper agent, will compare favorably with teak. The optimum curing conditions of several phenolic resin adhesives are presented as determined by an acetone extracting procedure. The results are presented for an attempt to replace the acetone extraction procedure by an x-ray diffraction method. X-ray diffraction patterns are presented of wood, -cellulose, and a phenolic adhesive. The viscosity characteristics of mixed Cascophen LT-67 phenolic adhesive are given. These viscosity correlations are based on the flow of material through an orifice.
