Abstract: We have developed a new pattern for continuous strand fiberglass mat which gives improved torsional rigidity to the molded structure. The pattern is basically an elongated elliptical loop where the strands lay on the conveyor and look like lazy whirl formations or concentric circles with diameters dependent upon properties such as bending rigidity and torsional rigidity. The lay-down pattern looks cycloidal in nature. Elongated elliptical strand loops become further elongated until at some point they also contain "pigtails" or somewhat straight strands with small elliptical loops oriented in the cross-machine direction.
