Abstract
A method for manufacturing an electrically conductive composite material includes obtaining a composite material which includes a thermoplastic matrix and short carbon fibers and is free of carbon nanotubes, preheating a furnace until a predetermined target temperature is reached, inserting the composite material into the preheated furnace once the target temperature has been reached, and heating the composite material in the furnace at the predetermined target temperature which is kept constant for a predetermined duration.
