Development of a carbon fibre frame for regional motorcycling championships

Abstract

[EN] Carbon fiber is most often used in high-level competition vehicles for its physical and mechanical properties. The goal of this work is to design and manufacture a motorcycle frame for regional championships, spreading the use of composites technology to teams with fewer resources. The design of the motorcycle used available parts to get the required geometrical features, while keeping in mind that the frame can only be manufactured in a single section, without adhesive bonds to be applied later. The calculations have been carried out using Ansys Workbench software, through the ACP (Ansys Composite Prepost) module of composite materials. The final result is a frame that is 30% lighter than the ones used in the same category, creating a more agile handling and a greater power-to-weight ratio.
