Study on the effect of polymer composite materials on the mechanical properties of sports equipment
Sporting equipment requires knowledge of the mechanical properties of proposed materials.The mechanical properties of composite materials are often not as simple to obtain as those of conventional ma-terials,in which case micromechanical modelling could be used in conjunction with CAD software.A mi-cro-mechanical model was used to predict the flexural modulus of composite materials,based on the as-sumption of partial interfacial adhesion between composite components.It was found that the partial adhe-sion model was both practical and consistently accurate.The partial adhesion model accounted for adhe-sion between components by considering an'effective shear value'at the interface.The model was com-pared to experimental data for glass,wood and carbon-fibre reinforced polyethylene.It was shown that the adhesion coefficient ranged between 0.1 for carbon fibre,0.5 for glass fibre and 0.8 for the wood fibre composites.It was shown that using micro-mechanical modelling to predict composite mechanical proper-ties,as opposed to simulating the comprehensive composites structure,computer processing time and file size can be reduced with little compromise in simulation accuracy.
