Characterization and Impregnation Studies of Dynamic Polymer Systems for Basalt Fiber Reinforcements

Summary

Beschreibung The development of sustainable fiber-reinforced composites requires novel matrix materials that combine high mechanical performance, durability, and recyclability. At the chair of carbon composites, vitrimer-coated basalt fibers are being investigated as a promising alternative to conventional thermoset-based reinforcement systems for concrete applications. In addition to vitrimer materials, other emerging matrix systems with comparable reprocessability, repairability, or dynamic network properties may be considered and benchmarked to identify suitable candidates for future composite reinforcement concepts. Following an in-depth familiarization and literature review, this thesis focuses on the characterization of advanced matrix systems and their interaction with continuous basalt fibers. Different material systems will be investigated regarding their processing behavior, rheological properties, impregnation performance, and suitability for fiber reinforcement applications. Experimental studies will include laboratory-scale impregnation trials and systematic parameter investigations using a Design of Experiments (DoE) approach. Relevant process parameters such as matrix viscosity, impregnation duration, temperature, curing conditions, and fiber volume content will be evaluated. The results will contribute to the identification and optimization of sustainable matrix systems for basalt fiber composites and support the development of recyclable reinforcement solutions for construction applications.
