Abstract
A laminated face ply for aircraft windshields provides improvement in window performance. The laminated face ply incorporates an outer glass face ply and an inner glass ply of thin, chemically strengthened glass having substantially identical thicknesses of about 0.026'. A first urethane interlayer bonds the outer face ply to the inner ply. The thickness of the first urethane interlayer is sufficient to accommodate thermal stresses arising between the outer ply and inner ply, but sufficiently thin to limit deflection of the outer ply for impact resistance. A second urethane interlayer is employed to bond the inner glass ply to a structural ply of the windshield. The second interlayer has a thickness substantially identical to the first urethane interlayer to accommodate thermal stresses arising between the inner glass ply and the structural ply of the windshield while similarly limiting deflection of the inner ply with respect to the structural ply of the windshield for improved impact resistance.
