SABIC Innovative Plastics (Pittsfield, Mass.) has introduced two new resin systems for use in aircraft interior applications. Ultem polyetherimide (PEI) Composite Aerospace Board (CAB) sheets, codeveloped and manufactured with Crane & Co. (Dalton, Mass.), provide an alternative to thermoset aramid fiber-reinforced honeycomb composites. Ultem CAB sheets can be thermoformed, offer a range of high-performance properties, are recyclable and offer the potential to be refurbished with a newly developed decorative film layer to extend its useful life while still meeting U.S. Federal Aviation Admin. (FAA) requirements. The other product is a line of carbon fiber-reinforced Ultem PEI resins. With loadings of 40 percent carbon fiber, these resins are said to feature good stiffness and flow, properties that make possible the production of thin-walled molded parts that can replace airline-grade die-cast aluminum in structural components, with up to 50 percent weight savings and up to 40 percent increase in strength. Potential applications include structural supports, armrests, footrests and galley structures, such as coffee maker chassis and tray table arms. The resin complies with FAA flammability (FAR 25853) and smoke-density and heat-release requirements for Ohio State University (OSU) standard 65/65.
