Confirmation of Candidature - Impact of Different Fibre and Resin Types on the Durability of Polymer Composites : Abdullah Iftikhar

The worldwide utilization of fibre-reinforced polymer (FRP) composites in civil engineering and construction is increasing rapidly. In this application, the durability and long-term performance of FRP composites need to be demonstrated because these advanced materials are likely to be directly exposed to aggressive environmental conditions. This research will investigate the role of constituent materials (fibres and resin) and their interface and their contribution on the long-term performance and durability of FRP composites when exposed to simulated aggressive environments like hygrothermal, saline, and solar ultraviolet (UV) radiations. The physical and mechanical properties of different fibre types (glass, carbon, basalt, and flax), resin systems (epoxy, bio-epoxy, and vinyl ester), and their interaction will be investigated at different exposure durations. Single yarn fragmentation tests, microstructural and thermal changes using SEM, FTIR, and DSC, and single yarn pull-out tests will be implemented to identify the underlying degradation mechanism in the constituent materials of FRP composites systematically. The outcome of this research will significantly contribute to predicting the long-term performance of FRP composites under harsh conditions and understanding the role of fibres, resins, and fibre/matrix interface in composite degradation and stability.
