Momentive Specialty Chemicals Inc. (Columbus, OH) is debuting a new, more efficient epoxy system for mass producing lightweight carbon-fiber structural components at the JEC Europe 2012 Composites Show, March 27-29 in Paris.
The new system, a combination of Epikote Resin 05475 and Epikure Curing Agent 05443, enables direct infusion of carbon fiber material using industrial-scale high- or low-pressure resin transfer molding (RTM) process equipment, with curing in less than five minutes.
"Carbon fiber-reinforced epoxy composites can deliver weight savings of up to 60 percent compared to conventional steel designs," says Nipesh Shah, VP, global marketing and business development of the company's Epoxy, Phenolic and Coatings Division. "Our new system makes switching to epoxy composites for the chassis, semi-structural parts and exterior body more attractive because it makes production faster and more predictable." The Epikote Resin 05475/Epikure Curing Agent 05443 system features low viscosity, a relatively long injection window, excellent wetting and adhesion to carbon fibers, and superior thermal and mechanical performance.
