摘要

Currently the information on the tensile strength properties of laminated veneer lumber made from Malaysian tropical timbers is not available. This is due to the difficulty of making the end-fastening device. In this study, the tensile strength behavior of LVL manufactured from Malaysian tropical timbers was evaluated. The 50 mm thick LVL panels were manufactured using 13 and 17 layers of veneers from Kedondong (Canarium,spp), Keruing (Dipterocarpus , spp) and Bintagor (Calophyllum, spp). The tensile strength test was carried out using in-grade size specimens. In order to carry out this test, a special tensile grip was fabricated using the model suggested in ASTM D198. The tests were conducted according to ASTM D198 (Static Test of Lumber in Structural Size). The tensile strength properties evaluated include tensile strength, modulus of elasticity and Poisson ratio. Effect of timber species and the number of veneer layers on the tensile strength properties were analysed statistically. The relationship between tensile stress and bending stress is also discussed.
