RESEARCH ON USING PLYWOOD MADE FROM DOMESTIC SPECIES OF WOOD FOR LONGBOARD MANUFACTURING
Abstract
The paper presents the results of the experimental research on replacing the actual plywood generally used for longboards manufacturing with plywood made from domestic species of wood, namely beech and birch wood. The research is focused on the determination of bending deformation, modulus of rupture (MOR) and modulus of elasticity (MOE) for bending strength of the investigated plywood specimens according to SR EN 310-1996, and also of the longboards made from the three types of plywood. The research was conducted on standard specimens made from beech and birch plywood on one hand, and on specimens made from a combination of bamboo and Canadian maple plywood, on the other hand, having the sizes and testing position according to SR EN 310-1996. In addition, boards having sizes and shapes of actual longboards were also tested for bending deformation, using in all cases a constant distance of 500mm between supports when applying the force, equals to the distance between track rollers of longboard. The conclusion of the research is that the domestic plywood made from beech and birch wood could replace in the future the actual plywood used in the longboard manufacturing
