Withdrawal strength and bending resistance of L -shaped nail′s joint in particleboard and MDF

Effect of nail length (32, 42, 48 mm), the nail number (2 and 3) and the kind of particleboard and MDF on tensile strength and bending moment of the joint were investigated. The member dimension of 10*15*1.6 cm was selected in L–shaped joint manufacture and the adhesive was not used in the production of the joints. Using 4 replications, a total of 96 samples of L shaped joints were fabricated. Bending and tensile strength of the joints was measured. Results showed that the interaction of variables; nail penetration length, nails number and the material of the joint were not statistically significant on tensile and bending. The length and number of the nails increased the strength. Joints produced with MDF and the penetration length of 48 mm and 3 nails showed the greatest flexural strength and the joints produced with MDF and the penetration length of 42 mm and 3 nails showed the greatest tensile strength
