ABSTRACT:
Discrete carbon or other electrically conductive fibers are added to a fluid formulation of settable resin in a bath, and a number of tows of non-conductive fibers, for example glass, are drawn through the bath, entraining and partly aligning the conductive fibers and being wetted by the resin. The tows are then bunched into a bundle, causing most of the conductive fibers and concentration zones to render the moulded product conductive to electrostatic charge.
