Abstract
In various embodiments, a method of making a cutting mat backing includes creating a roving by wrapping a fiber material around a rotary cylinder under tension to form a plurality of layers. Each of the plurality of layers is angled with respect to a central axis of the rotary cylinder and the roving has a normalized axial flexural rigidity of from 2 lbf.in2 to 30 lbf.in2 over a beam width of 1 inch and a ratio of normalized circumferential flexural rigidity to normalized axial flexural rigidity of from 1:1 to 30:1. The method further includes infusing the roving with a polymer resin and curing the resin via electromagnetic radiation to form the cutting mat backing. Cutting mats including the cutting mat backing are also described.
