Abstract
The effect of finger joint location and distance from joint to joint one another on 3 point mid-concentration bending strength properties was investigated in this experiment. Resorcinol-phenol formaldehyde (RPF) and aqueous vinyl urethane (AVU) was used to domestic Pinus densiflora Sieb. et Zucc and imported Picea sitchensis Carr. that have been cut to different width of 0.15 mm between finger tip and root width and the distance from loading point to finger joint was 0, 30, 40, 50, 60 mm. The effect was not found on the location and distance of finger joint for bending modulus of elasticity, while the efficiency of bending strength property increased proportionally as the location of finger joint from the load point and the distance between finger joint increased. No influence was shown by finger joint location and distance beyond 3 times of specimen thickness, since similar values were shown between the solid wood and no destruction occurred materials.
