Abstract
A carbon-based lightning strike protection system is described that utilizes flexible graphite and porous carbon. The carbon-based lightning strike protection system may be produced in the form of a panel that may be applied over the surface of an object to be protected or may be created directly over the surface of the object. The carbon-based lightning strike protection system is readily adaptable to high temperature applications.
Claims13
A lightning strike protection system comprising:
- a graphite spreader shield layer, wherein the graphite spreader shield layer comprises flexible graphite having an in-plane electrical conductivity that is about 100 times greater than the flexible graphite through-plane electrical conductivity;
- and
- a porous carbon thermal insulating layer comprising carbon foam having a thermal conductivity below about 0.5 W/mK and a thickness not greater than about 0.5 inches, wherein the porous carbon thermal insulating layer is positioned between the graphite spreader shield layer and a surface of an object to be protected.
