Differences Between Woven Rovings and Chopped Strand Mats
Woven roving and chopped strand mat (CSM) are both types of fiberglass reinforcement materials used in composite manufacturing, but they differ in their structure, appearance, and applications. Here are the main differences between woven roving and chopped strand mats: Structure and Composition: Woven Roving: Woven roving is a heavy, high-strength fabric made by weaving continuous glass fibers in a crisscross pattern.
