Non-woven, and synthetic fiber based core mat is used to build laminate bulk and block print-through.
Produced in a variety of widths and thicknesses, core mat is also known as a laminate bulker or a core fabric. It is used to build laminate thickness (increasing stiffness) and to isolate laminate shrinkage from the cosmetic gel coat surface. In applications requiring good cosmetics, core mat is used to improve surface quality; particularly with darker, more revealing gel coats. Popular in the marine and recreational vehicle industries where surface finish is critical, core mat wets out quickly and is conformable to fit mold contours.
