Abstract

Fibre-reinforced polymers (FRP) have significant advantages over metals due to their excellent specific mechanical properties. However, their range of application is often limited by insufficient thermal properties. In order to expand the range of applications of thermoplastic composites in particular, it is necessary to improve their thermal properties, especially thermal conductivity. The use of novel veils doped with nanofillers offers a high potential for tailor-made modifications of composite properties depending on the filler used and the composite design. However, the integration of thermoplastic veils with nanofillers into composite structures is associated with some fundamental challenges: modification of the composite design and thus the change of material properties as well as change of the manufacturing process and the process parameters. To investigate these phenomena, polyphenylene sulphide (PPS) veils doped with multi-walled carbon nanotubes (MWCNTs) were integrated into carbon fibre-reinforced polymers (CFRP) with acrylic resin system. For this purpose, various lay-up setups of the fibre reinforcement and the modified veils were defined and the composite structures were fabricated using the wet compression moulding (WCM) process. The influence of the process parameters on the infiltration and consolidation of the composite structure with acrylic resin was investigated. The composite structures were evaluated using non-destructive testing methods such as ultrasonic as well as microscopic observations. In addition, extensive thermal and mechanical tests were carried out to determine the influence of the integrated veils on the composite properties and compared with reference structures. As a result, a basis for a model-based and integrated material development process was created.
