estrutura laminada compósita, método para prover proteção contra relâmpagos para uma junta de ligação, e, tanque de combustível de aeronave. dois laminados de fibra de carbono compósita (24, 26) são unidos por uma linha de contato (22) tendo porções expostas ao ambiente circundante. a linha de contato contém tecido fino (32) embebido em camadas adesivas (34, 36) tendo uma condutividade elétrica e impedância que combinam com aquela dos laminados no sentido de mitigar os efeitos de relâmpagos. Two composite laminates are joined together by a bondline (22) having portions exposed to the ambient environment. The bondline contains scrim (32) having an electrical conductivity and impedance matched to that of the laminates in order to mitigate effects of lightning strikes.
