According to the preferred embodiment, the TPE comprises graphite fiber having a nickel-copper-nickel coating formed thereabout that is suspended within an elastomer, which preferably comprises polyvinylchloride. The TPE of the present invention is particularly well-suited for reducing radio frequency electromagnetic radiation reflected by gaps formed between adjacent panels of a structure, and is particularly well-suited for the maintenance and repair of low observable aircraft. The TPE of the present invention may further be modified to include carbon black filler.
