Recently, the Ford Bronco SUV garnered significant attention after a video surfaced depicting its roof cracking, revealing an interlayer that resembled cardboard, sparking safety concerns among the public. In response, Ford clarified that the roof employs a sandwich-like layered construction, where the core layer comprises a polyurethane glass fiber-reinforced paper honeycomb composite material.
