ABSTRACT:
Plastic bristles made of a thermoplastic or thermosetting plastic material are proposed, into which reinforcing fibers in the form of at least one endless fiber bundle are embedded to increase the bending strength, abrasion resistance, and breaking strength. The fibers preferably are composed of glass fibers, aramid fibers, carbon fibers, or high-strength polyethylene fibers. The plastic material of the bristles can be extruded together with the reinforcing fibers, but it is also possible to manufacture the plastic bristles in a pultrusion bed.
