Graphite-epoxy composite systems for Joule heating based de-icing
Abstract Ice accretion and build-up in low temperature environments are issues plaguing many different branches of the industry. Recently much work has been done into the development of active de-icing systems based on carbon materials and their composites. The following research presents an investigation into graphite/epoxy composite materials made by a simple casting method with cheap materials and scalability potential, intended for de-icing applications based on Joule heating. The examination has been carried out for samples with different amounts of carbon filler using IR thermal imaging to measure sample heating under the influence of electrical current under constant voltage. Measured electrical currents were then analyzed to examine changes in samples' electrical resistance dependent on temperature. Results provide a positive outlook for further experiments and development for this type of material toward its potential application.
Highlights Graphite-epoxy composite can work as a de-icing device, with optimal performance for the addition of 40–50wt% of graphite. Simple casting method is a viable route for the production of de-icing system based on an epoxy resin/carbon composites. Use of graphite as a filler in active de-icing systems results in devices far less expensive than those using nanocarbons.
