  • Lightning strike and electromagnetic protection system
    Patent number: 10709041
    Abstract: A composite article for incorporation at the surface of an assembly, the composite article being capable of withstanding a lightning strike by dissipating the energy of the lightning strike and by shielding the assembly from electromagnetic energy associated with the lightning strike. The composite article has a base structure made of a material exhibiting electrical conductivity that is inadequate to dissipate lightning strike energy and also inadequate to shield the assembly from the associated electromagnetic energy. Against the outer face of the base structure an electrically-conductive lightning shield is secured. The lightning shield has a substantially uniformly-distributed embedment of electrically-conductive nanostrands in a matrix that otherwise exhibits electrical conductivity that is inadequate to dissipate lightning strike energy and inadequate to shield the assembly from associated electromagnetic energy.
