An experimental program was conducted which demonstrated that a 2-ply windshield could be constructed with impact performance, as measured in the laboratory, comparable to that of standard 3-ply HPR windshields with Inner Shield and Securiflex laceration shield treatments. The 2-ply windshield construction chosen for testing contained an outer ply of float glass and an inner multilayer laceration shield. This laceration shield is comprised of a polyvinyl butyral interlayer (0.95 mm thick), a polyester 'laceration shield' (0.13 mm thick), and a proprietary abrasion-resistant coating (these three materials being produced by Du Pont). Full-scale sled tests were performed of the 2-ply construction using unrestrained Hybrid III dummies at the Safety Research and Development Laboratory (SRDL), GM Milford Proving Ground. These tests, which provided a 'realistic' evaluation of windshield performance in frontal impacts showed that the 2-ply windshield is a viable concept in terms of occupant safety. For a 3.18-0.95-0.13 mm 2-ply construction, frontal impact performance (as measured in terms of facial laceration, penetration resistance, and occupant injury indices, including HIC) was found to be comparable to that of 2.29-0.95-2.29 mm 3-ply windshields with Inner Shield and Securiflex laceration shield treatments. It is important to note, however, , that important technical issues such as mounting system, noise transmission, and and vehicle structural response need to be addressed prior to considering this experimental 2-ply construction for production field usage.
