FIELD: process engineering.
SUBSTANCE: transmissive plastic composite with better acoustic properties is intended for glazing. Said composite consists of, at least, two outer polymethacrylate layers and thermoplastic polyurethane layer arranged there between. Said polymethacrylate layers include polymers with, at least, 80% of polymethacrylate links and up to 20% of acrylate links. Additionally, said composite incorporates scratch-resistant layer made on one or both sides of polymethacrylate layers. At least, one of two outer layers is painted and comprises IR-reflection pigment(s) and additives, as well as impact strength modifier. Said composite is used for fabrication of car body component. Said composite is made by heating plastic plates and moulding them.
EFFECT: higher mechanical and acoustic properties.
