Shielding cover for sports cars

SpecialChem / Feb 16, 2010

The underbody shielding of the latest Z4 sports car of the German automaker BMW are made by the German automotive part manufacturer Takea Automotive Systems GmbH from a glass mat thermoplastic material from Quadrant Plastic Composites i.e. SymaLITE™. In fact, this underbody shielding, which allows to improve car’s aerodynamics and fuel efficiency as well as to reduce noise, is made of a layered, sandwich-like core structure providing high acoustic properties and higher stiffness-to-weight ratio compared with injection molded parts or other alternative material solutions. SymaLite is said to be a composite material in which the orientation of its glass fibers give it rigidity and shape at low weight. By varying the mix of fibre and polypropylene (PP) matrix in relation to the functional surface layers, the material properties can be adapted to match the performance demands of the part, giving greater design and processing flexibility than other materials. The open cellular structure and the sandwich construction provide the acoustic properties, reducing engine and gearbox noise and driving noise levels.
