Selected construction and material aspects of moulded plywood production for use in sports equipment

Selected construction and material aspects of moulded plywood production for use in sports equipment. Within this work a study on different variants of cold glued moulded plywood intended for parts of sports equipment (eg. tops of skateboards) was carried out. 7-layer moulded plywood was diversified both in terms of the veneers arrangement (4 variants) and applied veneers (obtained from 3 types of wood: pine, beech and rock maple). Moulded plywood was made with the use of PVAc adhesive. All variants were tested for strength properties (MOR, MOE, impact bending strength and impact value). Considering the fact, that the moulded plywood used in sports equipment (eg. tops of skateboards) is most often destroyed due to dynamic forces, as the most advantageous variant of the test 7-layer plywood with two outer layers parallely glued, made of a rock maple veneers was considered.
