Chopped Strand Mat

This is a fiberglass fabric consisting of randomly oriented glass strands, held together with a resin binder. It’s useful in applications with tight curves or corners and as part of a greater sandwich composite, where it adds thickness and improves adhesion with different fabric types in the laminate. Many choose to tear this fabric instead of cutting, to preserve the length of fibers along the edge, helping it bond with other layers.

Please Note: Use only vinyl ester and polyester resins, as they contain styrene which is necessary for proper binding. Chopped Strand Mat is not compatible with epoxy resins.
