Abstract
Abstract A novel mat composite is shown in which a plurality of glass fibers, strands or rovings are carried on a fluid permeable sheet with two generally parallel ribbons of mastic on each side of the sheet inboard of the edges affixing the fibers, strands or rovings to the sheet and maintaining the fibers, strands and rovings generally parallel to each other.
