CARBON FIBER SMC RESIN SYSTEM At INEOS Composites, we strive to be good partners by meeting the expectations that are important to our customers. Today, that means we’re focused on reducing our environmental footprint, while continuing to provide the innovative products and sustainable solutions our customers require. The automotive industry needs to quickly meet the National Highway Traffic Safety Administration’s (NHTSA) Corporate Average Fuel Economy (CAFE) standard requirements. The goal of CAFE is to continue to reduce energy consumption by increasing the fuel economy of cars and light trucks, thereby reducing the amount of pollutants released into the atmosphere. NHTSA’s new standards rapidly increase over the next several years, which is driving original equipment manufacturers (OEM) to design and produce lighter vehicles. According to the U.S. Department of Energy’s Vehicle Technologies Office, a 10% reduction in vehicle weight can result in a 6–8% fuel economy improvement. However, traditional lower-density sheet molding compounds (SMC) may not provide sufficient strength and toughness for structural applications. The Arotran™ 300 resin system was developed to address the automotive industry’s need for lightweight, high-strength resin systems utilizing carbon fiber (CF). Parts made with this resin technology will produce carbon fiber SMC structural composites with very high mechanical properties. The resin system is based on epoxy vinyl ester chemistry and nano-composite technology. Mass reduction, low tooling costs, noise reduction, and heat and corrosion resistance are all deliverables with the use of the Arotran™ 300 resin system in structural applications.
