Study on the Processing of Finger-jointed Lumber
Finger-joints from four species of Eucalyptus, E. citriodora, E. exserta, E. urophylla × E. grandis, E. grandis, were prepared by using two kinds of adhesive, PVAc and API, to determine optimum processing conditions. The effect on performance of finger-joints using different density samples, different combination methods, different finger profiles and different finger types, was analyzed. The results have shown that there were some differences in finger-joints MOR by using different kinds of adhesive, and the MOR of finger-joints with API was higher than that of PVAc. The difference between fingertip and root(ΔT) also played an important role in the performance of finger-joints, the MOR of the finger-joints was highest when theΔT was 0.1mm when tested withΔT of 0, 0.1 and 0.5mm. End pressure also affected the MOR of finger-joints; when theΔT was 0.1, the optimum end pressure were 10kN, for E. citriodora, E. exserta, E. grandis × E. urophylla, and 11.5kN for E. grandis wood. MOR and MOE of finger-joints with different finger type V was almost equal with type H.
