Kevlar is a high tensile strength and high modulus composite fabric that is great for canoes, kayaks, and racing shells where maximum strength and minimal weight are critical. Impact tear and penetration resistance is far superior to fiberglass. 9 oz, 58" wide. Twill weave kevlar cloth drapes around corners easier than regular kevlar cloth, and twill weave also wets out better than plain weave kevlar. Twill weave is a basic pattern discernible by a diagonal rib, or twill line. Each end floats over at least two or more consecutive picks enabling a greater number of yarns per unit area than a plain weave, while losing little fabric stability. This type of fabric looks different on one side than on the other. The fabric is .024 in thick.
