Abstract

Joints are important components of wooden structures that provide continuity to wood and wood products. In this study, a finger joint with two finger lengths of 5 and 10 mm was investigated with two adhesives: epoxy and polyvinyl acetate reinforced with cellulose nanocrystals (CNC) and nanoclay at three levels of 0%, 0.4%, and 1.5% using the free bending vibration method in a free-ended beam on a plywood. The results indicated that except for vibration damping, the values ​​at the 10 mm joint length were significantly higher at the 95% confidence level. The effect of CNC was also significantly higher than that of nanoclay at the 95% confidence level. Both nano-based adhesives at 1.5% had significantly better results. Epoxy adhesive also had significantly better results than polyvinyl acetate adhesive. Overall, the joint with a 10 mm finger length jointed with epoxy adhesive and reinforced with 1.5% CNC yielded the best results.
