Is the Car Windshield Made of Laminated Glass?
2 Answers
Car windshields are made of laminated glass. Here is some relevant information about car windshields: 1. Introduction: Car windshields are generally designed as a single large curved piece with certain curvatures on all sides. This type of curved glass is a product that requires high technical standards, whether in terms of the manufacturing process or the assembly, as it involves various issues such as vehicle model, strength, heat insulation, and installation. 2. Function: The windshield provides a survival space for passengers. When impacted and shattered, the glass breaks into small pieces with blunt edges, reducing the risk of injury to passengers. Currently, car windshields are mainly made of laminated tempered glass or zoned tempered glass, which can withstand strong impacts.
Modern car windshields are mostly laminated glass, which feels smooth and flat but actually has a lot of intricacies. It's like a sandwich with three layers—two sheets of glass with a plastic film in between, technically called a PVB interlayer. Once, while reversing, I accidentally scraped against a tree branch, causing the glass to crack with a spider-web pattern but it didn’t shatter completely, all thanks to this 'glue' holding the fragments together. This design is particularly safe—even in a collision, the glass won’t shatter into pieces and injure your face. It also blocks UV rays and reduces noise. If a small stone hits the windshield during heavy rain, minor cracks can often be repaired, but larger cracks require replacing the entire windshield.
