Project Description

The application of electric current to a carbon fibre panel has recently been shown to be capable of curing it, with properties that match or exceed those specified by the manufacturer. At present we have published data from the largest panels made in this way, measuring up to 60 cm by 60 cm, and we have also started to make sandwich panels and shaped panels, including parts for UAV’s. This project seeks to increase the panel area and complexity, while maintaining the mechanical properties. It will also investigate the production of more complex parts such as L-shaped and top-hat stiffeners, preferably moving towards co-cure of panels and stiffeners. One key aspect of the project will be the investigation of consolidation and void content in panels cured using directly applied electric current, as void content and fibre volume fraction are critical to the mechanical properties of component. Comparison will be made to conventionally cured parts, and the electrical approach optimised to maximise the mechanical properties. Finally, comparison of the energy requirement for conventional cure and direct electrical cure will be considered to determine the viability of the process as a commercial manufacturing route.
