ABSTRACT:
The disclosure of this invention describes a composite glass fiber structure that includes first and second layers of glass fibers extending in adjacent parallel relation; synthetic resin coating the fibers of each layer and providing a bond holding the layers together in the parallel relation; the fibers of the first layer having smaller diameters than the fibers of the second layer; the first and second layers being gas compressed to have densities of between about 0.25 and 0.45 lbs. per cubic foot.
