ADVANCED ALIPHATIC POLYURETHANE RESINS FOR HIGH DURABILITY AND SUPERIOR BALLISTIC PERFORMANCE LAMINATED GLASS

摘要

Advanced aliphatic polyurethane (PU) resins have been developed for manufacturing laminated ballistic resistant glass that are lighter and more durable than commercially available glass. The newly developed aliphatic PU resins have very high adhesion strength to glass, polycarbonate and polymethyl metacrylate (PMMA). They also have an excellent optical quality and generate lower thermal stresses by using low processing temperatures during glass lamination. This paper discusses the adhesion, high temperature creep, and aging properties of the new optical aliphatic PU that offer the potential for reducing delamination failures, increasing the ballistic performance, and reducing the weight of future laminated transparent armor designs.
