Abstract

In this research, the effect of Polyvinyl acetate (PVAc) adhesive reinforced with modified carbon nanofibers (CNF) were studied in three levels (0%, 0.4%, 1.5%) on the strength properties of joints commonly in the furniture industry. Modified carbon nanofibers were used as chemically modified surface to improve the dispersion in polymer matrix. The bonding of the test specimens were made using of cut out medium density fiber board (MDF) pieces with desired dimensions and dowel wooden with 6, 8 and 10 mm in diameter, and penetration depth at three levels using polyvinyl acetate adhesive reinforced with modified carbon modified nanofiber. Totally, we have 27 treatments with three replicates. The evaluation of the bending moment capacity of test specimens made with freshly formulated adhesive carried out and the effect of other variables was performed on the joints made under tensile loading at a speed of 3 mm/min. The results showed that increasing the weight percent of carbon nanofibers, the diameter of the wooden dowel and the penetration depth and the moment capacity compared to the control samples was increased by 1.6, 1.5 and 1.3 times, respectively. The 0.4% w/w carbon nanofibers, 10 mm diameter and L3 wooden dowel penetration depth had the greatest effect on the strength of the joints.
