Abstract

In the present paper, the topic is the result of a partnership of the University of Bayreuth and several small and medium sized economics. With support by the government (project ZIM) high end composite tubes reinforced by basalt fibres, were researched and developed. The Conclusion is a more effective usage of the strength potential of basalt fibres. The examined applications were tubes used in conveyor belts which were enhanced with FE-simulations. Fundamentals for a realistic simulation was an intensive corporation with the involved industrial partners regarding the boundary conditions. Providing characteristic values for strength criterias based on their experience was an essential part. In consideration of the current manufacturing technology optimised fibre composite tubes were established. The optimisation focusses on an advanced layer structure considering the applied boundary conditions. Restraining the tube ends and the existing loads are reflected in several simulations. Looking at the often cited Hashin criteria characteristic strength properties were assessed. Result is an even more economic manufacturing of the fibre reinforced composite tubes in the consequence of reducing different, necessary layers. Beside this a resource-efficient production with a sufficient strength consideration is performed.
