Abstract

The present disclosure describes a textile article for radio frequency (RF) absorption and attenuation. The textile includes a laminate that is formed via curing a wet laminate at room temperature for a cure time, the wet laminate comprising a resin substrate and a reinforced fiber matrix. The reinforced fiber matrix may include one of a bamboo fiber matrix, a cotton fiber matrix, a polyester fiber matrix, a nylon fiber matrix, or a wool fiber matrix. The resin substrate may include a first portion of iron oxide particles and a second portion of the elastic polymer solution, the first portion of iron oxide particles being based at least in part on an RF signal range that the textile article is configured to absorb and attenuate. For example, the iron oxide particles may include Fe3O4Fe, Fe3O4Ni, or Fe3O4, and/or so forth.
