Bonding Quality of Fiber-Wood Interface with Wood Adhesives

Abstract

Effects of fiber fabric type, glue spread, adhesive kind and angle between carbon fiber and wood grain on bonding quality of fiber-wood interface were investigated to make it clear whether wood adhesive can be used in fiber reinforced wood products. Four different kinds of fiber fabric were bonded into poplar sample with three different adhesives and three different glue spread. Shear strength of samples were measured by compression shear test. The results indicated that bonding quality of GFMa (Glass Fiber Mat)-wood interface was the best of all and 400g/mm2 was the optimal glue spread for various adhesive and adhesion. Results of control experiment of angle between carbon fiber and wood grain indicated that bonding quality of samples with carbon fiber parallel to wood grain was better than that with carbon fiber perpendicular to wood grain.
