Hankuk Carbon selected Solvay's tougheners for automotive applications

Solvay’s impact modifiers enhance the toughness, heat resistance and processability of a carbon fiber prepreg developed by Hankuk, a composites manufacturer based in South Korea, for automotive fenders and roof components.

The prepreg is intended for use by a major U.S. automotive OEM for a commercial automotive fender and roof application. Solvay’s broad offering of such lightweighting solutions underscores the company’s proactive support of the industry’s growing adoption of carbon composites.

According to the Institute for Advanced Composites Manufacturing Innovation (IACMI), fiber-reinforced polymer composites could help reduce the weight of conventional passenger cars by 50 percent and improve fuel efficiency by nearly 35 percent without compromising performance or safety. Fabricated using advanced polymer technologies, composites also eliminate corrosion and improve weather resistance vs. metal. They also require lower maintenance.

Solvay’s Virantage polyethersulfone (PESU) tougheners can increase the impact strength of thermoset composites parts by nearly 40 percent and provide a step-change improvement in heat resistance. Because Virantage PESU micropowders are compatible with a range of epoxy systems, they disperse more quickly vs. conventional impact modifiers, thereby improving processability and consistency in high-volume composite production. Already widely used in prepreg production for commercial and military aircraft applications, Virantage PESU tougheners are attracting increasing interest from automotive engineers as an integral part of their vehicle lightweighting strategy as they seek to meet emerging CO2 emission standards.
