Design of snowboards with renewable resources
Pages: 20 - 24
Fibre-reinforced plastics (FRP) are often used in sports industry, especially for the structure of cycling, racket and sliding sports equipment. Computer-based product development strategies, that are commonly used in the aerospace and automotive industry, are also be deployed in the sports industry during the last years. Hence, the stiffness and strength of new snowboards designs could be simulated by using finite element method (FEM). By using such computer-aided engineering (CAE) tools the influence of different bio-based and renewable materials on the mechanical properties of the sliding sports equipment can be analysed. In this work an ecological snowboard made from bio-based and renewable resources consists of flax-fibre semi-finished products, bio-based thermosetting resin, bio-based sidewalls and a core element of poplar solid wood is developed. By means of the FE-simulation the parameters ply angle and ply thickness of the flax-fibre semi-finished product as well as the core thickness are variated, until the bending stiffness and bending stress is equivalent to a conventional snowboard. The volume-FE and shell-FE model will be verified on manufactured prototypes with a 3-point bending test according to DIN EN ISO 14125 (2011).
