SMC (Sheet Molding Compound) and BMC (Bulk Molding Compound) thermoset composites are extensively utilized across the automotive industry for a wide array of parts in passenger cars, trucks, and tractors. Their widespread adoption is due to a unique combination of properties including high thermal stability, a low coefficient of thermal expansion (comparable to steel), excellent dimensional stability, high impact resistance, and relative lightweight. Furthermore, these materials readily accept high-quality paint finishes, meeting the Class A cosmetic appearance and rigorous paint/cure cycles required by the industry. Common applications include exterior parts like air deflectors, spoilers, window/sunroof frames, grilles, bumpers, and tailgates, as well as critical under-hood components such as headlamp reflectors, heat shields (for engine & transmission), and cylinder head covers. Notably, they are also key for battery housings and covers for electric vehicles.
