Abstract
During the cooking of a composite component including layers of fibers embedded into a matrix, a superficial pressure is exerted. This superficial pressure generates a deformation that causes local contacts of fibers of at least two layers without damaging these fibers. As a result, when an electrical current is applied on a side of the composite component, such as during a lightning strike or a short circuit, the added local contacts enable the electric current to flow along multiple fibers in the composite component, thereby avoiding significant spikes in temperature.
