Bonding Quality of Wood-FRP Interface with Ambient Curable Epoxy Adhesives
Effects of glue spread, adhesive kind and curing agent ratio on bonding quality of wood-FRP (Fiber Reinforced Plastic) interface were investigated to choose the optimal adhesive and condition of bonding wood-FRP composites. Two different kinds of epoxy resin and one kind of curing agent were used to bond wood-wood and wood-FRP samples with three different glue spread. Shear strength of samples were measured by compression shear test. The results indicated that bonding strength of wood-FRP sample with glue spread of 300 g/mm2 and curing agent ratio of 40% were the best, when using the same epoxy resin and curing agent. The shear strengths of wood-FRP samples were less than those of samples without FRP. The bonding qualities of samples with E-44 epoxy resin/T-31 curing agent system were better than those of E-51 epoxy resin/T-31 curing agent system.
