The FRP skin PET foam sandwich panel uses glass fiber reinforced plastic sheets (mixed with high-quality thermosetting resin and strong short glass fibers) and lightweight rigid PET foam as the core material. This lightweight, high-strength panel finds wide application in RVs, dry truck bodies, building wall panels, and other fields due to its excellent heat insulation, corrosion resistance, and ease of processing.
