Abstract

In this research, nanocellulose fibers were used as adhesive filler in the manufacture of plywood from wych elm (Ulmus globra). Then, the drop-weight impact of the plywood samples was investigated. For this purpose, the nanocellulose fibers were added to dry weight of urea formaldehyde adhesive at four levels of 0, 0.5, 1 and 1.5%. The "4-ply" plywoods were made with these adhesives that the layers in top and bottom were parallel and had two core layers perpendicular with top. In order to investigate the impact properties, plywood samples were tested in the drop-weight impact device. The maximum force on the samples, the displacement in maximum force, the energy consumed in the maximum force and the total absorbed energy were evaluated. The results showed that the sample containing 0.5% of the nanocellulose fibers had the best impact property and with increasing nanocellulose fibers, the impact properties were significantly reduced. Also, the impact resistances in the most of samples with nanocellulose fibers were better than the without nanocellulose (control) samples.
