Carbon Fibre Electrical and Thermal Conductivity Applications
topic
Carbon fibre electrical resistivity of 15 to 20 microohm metres enables carbon fibre composites to provide electromagnetic shielding effectiveness above 40 decibels, electrostatic dissipation in explosion-risk environments, and resistive heating when current is applied; axial thermal conductivity of 8 to 1000 watts per metre kelvin depending on graphitisation enables heat spreader and thermal management composite applications.
Role
Extends carbon fibre composite utility beyond structural reinforcement into multifunctional applications where electrical conductivity enables EMI shielding of electronic enclosures, lightning strike protection of aircraft structures, and resistive heated composite panels for aircraft ice protection and industrial heated tooling applications.
