Optimization of tensile properties and bond behaviour to concrete of fibre reinforcement strands produced within a dynamic fibre winding process

摘要

For the integration of reinforcement directly into additively manufactured structures a Dynamic Winding Machine (DWM) is developed, in which fibre material is consolidated to a strand and provided with a surface structuring. The produced reinforcement strands are formed into reinforcement structures with the help of an end effector attached to a robot. In combination with robotic integration strategies additively manufactured structures can be reinforced by this process. Results from mechanical, chemical and optical investigations presented in this paper aims to gain fundamental knowledge about the properties of the reinforcement strands produced by the newly developed process.
