Abstract

A filament-reinforced plastic article has a fluid-impermeable wall with a relatively low surface resistivity to prevent buildup of dangerous electrostatic charge. The article includes overlapping bands of filaments coated with plastic. A minor portion of the filaments in at least some of the bands is electrically conductive so that electrically conductive filaments are distributed throughout the wall.
