Contact resistance heating of unidirectional carbon fibre tows in a powder-epoxy towpregging line
Join us for a webinar with the winner of the 2023 Leslie Holliday Prize, exploring Contact resistance heating of unidirectional carbon fibre tows in a powder-epoxy towpregging line
What to expect
Contact Resistance Heating of Unidirectional Carbon Fibre Tows in a Powder-Epoxy Towpregging Line investigates how electrical contact resistance between carbon-fibre tows and roller electrodes affects Joule heating during towpreg manufacture.
The study experimentally measured contact resistance under different production speeds, tensions, and temperatures, and used thermal imaging alongside a finite-element model to predict tow temperature distributions.
Results showed that contact resistance significantly influences heating behaviour and must be considered to accurately control and optimise the towpregging process.
