Abstract

Methyl methacrylate wood polymer composite was made from sugar maple. Six commercial adhesive formulations were used to glue the wood polymer composite before and after treatment. Shear block tests were done dry and wet after boiling. Controls were glued, untreated wood, solid wood, and solid wood polymer composite. Phenol-resorcinol adhesive gave high strength and wood failure values for all treatment and test conditions; and isocyanate, epoxy, and polyvinyl acetate formulations performed well in some combinations.
