Original Abstract

The paper deals with the possibilities of enhancing the durability of wood bonds using the epoxy resin. These types of resin very often failed while exposing the water uptake when wood adherend swells and the bonds failed in bonding interface layer. Using the micro-cellulose fibers in epoxy resin leads to higher fracture toughness while the interphase could better accommodate the large dimensional changes of the wood. That was the reason, why the different amount of micro-ocellulose fibers in epoxy resin were applied and the durability test of single-lap wood joints were performed. The higher percentage of cohesive failure in wood adherend and higher shear strengths after exposing the hygrothermal exposures were achieved
