Carbon fiber reinforced polymer (CFRP) composites are rapidly substituting metals as load-bearing structural components in space and defense applications. While their mechanical properties are sufficiently high, their capability to shield electromagnetic radiation needs improvement to meet current and future requirements. We demonstrate a novel method of enhancing the electromagnetic interference (EMI) shielding capability of conventional CFRP.

This study investigates the delivery of a neutral solute through a porous-walled microtube with sinusoidal roughness under mixed electroosmotic flow pumping, using an external direct current electric field. The effects of various operating conditions, geometries, and properties of the wall, solute, and solvent are investigated. The novelty of this work lies in exploring the impact of sinusoidal roughness on the solute mass flux delivery.
