Advanced continuous carbon fibre reinforced polymer composites, offer a very attractive combination of mechanical properties, environmental resistance and lightweight which make them a superior choice for high performance applications. Some inherent characteristics of carbon fibre composites such as their low through thickness toughness and electrical conductivity, challenging manufacturing, limited recyclability and difficult maintenance and repair hold back the expansion of their application, thus limiting the significant environmental and robustness benefits associated with their adoption.
This project addresses these limitations through the utilisation of through thickness hybrid reinforcing elements offering significant improvements in electrical and delamination properties, the capability to monitor online the manufacturing process and development of damage in the material and the incorporation of heating and cooling. The Composites and Advanced Materials Centre at Cranfield has recently developed new methods of through thickness reinforcement using tufting of metallic elements to improve electrical and mechanical functionalities, new metal wire-based sensors in carbon composites and ways to combine the two and achieve property enhancement and advanced functionality within the same material solution.
This project is inspired by these developments to put forward a solution that will endow composites with improved through thickness electrical and mechanical properties, self-heating and self-monitoring functionalities. Activities in the project will cover hybrid through thickness reinforcement thread development, optimisation of material parameters through simulation, manufacturing of hybridised components, testing and validation of functionality and performance. Validation of the overall development will be carried out based on an aerospace use case.
Successful completion of this research will result in a new composite material combining advanced performance and multifunctionality. Achieving this while using materials and technologies that are fully compatible with the current state of the art will represent significant progress in the context of industrial application. The work will make full use of facilities within the Composites and Advanced Materials Centre including an electrical, thermal and thermo-mechanical characterisation suite, pilot scale composites manufacturing equipment including a tufting robot as well as the Mechanical Testing Lab in the School of Aerospace, Transport and Manufacturing.
