A protective system is provided including a material comprising a first and second surface opposite one another and a thickness, and where the first surface has a low-electrical resistance and the second surface has a high-electrical resistance that is higher than the electrical resistance of the low-electrical resistance surface, and the material conducts charge from the first surface to the second surface through the thickness. This can be provided in a bilayer structure where a first protective layer having a low-resistivity is disposed upon a second protective layer having a high-resistivity. This protective system is particularly useful for dissipating electrical charge, for example as a lightning strike protection system for composite aircraft.
