chopped strand mat fiberglass manufacturer

Chopped Strand Mat (CSM) is a random fiber mat that provides equal strength in all directions and is used in a variety of hand lay-up and open-mold applications. Chopped strand mat is produced by chopping continuous strand roving into short 1.5 to 3 inch lengths and dispersing the cut fibers randomly over a moving belt to from a “sheet” of random fiber mat. A binder is applied to hold the fibers together and the mat is trimmed and rolled. Because of is random fiber orientation, chopped strand mat conforms easily to complex shapes when wet-out with polyester or vinyl ester resins. Chopped strand mats are available as a roll stock product produced in a variety of weights and widths to suite specific applications.

Polyester is the preferred resin for wetting out this form of glass fiber material as it readily dissolves the styrene bonding agent.

Offered in various weights per square foot. The lightest version, veil mat, is used commonly as a finishing layer to mask any print-thru in a laminate schedule. This particular veil mat uses longer, thinner fibers than heavier mat weights also offered here. Think angel hair pasta to spaghetti fibers. Coarser, heavier mat is commonly used for bulk, random axis strength buildup and is also an excellent initial layer when bonding repair work.
