Carbon Fibre Ultem Resin for Aircraft Interior Parts

04 June 2010

Sabic Innovative Plastics has created a new high-performance compound based on aerospace carbon fibre technology coupled with Ultem polyetherimide (PEI) resin, supporting aerospace component weight reduction for both fuel and systems cost savings.

Vaupell, a global contract manufacturer of custom injection-molded components and assemblies with 60 years of experience, is working with Sabic Innovative Plastics to validate the new Ultem resin materials in aircraft tray table arm components.

Sabic say that these concept parts showcase the 50 percent weight savings and up to 40 percent improved strength of carbon-fibre-filled Ultem resin vs. die cast aluminium, and demonstrate how the company develops advanced, property-rich, sustainable materials to give aircraft customers a powerful competitive edge.

“Our new carbon-fibre-filled Ultem resin family is a great example of our strategy to further expand our premier technologies to solve our aircraft customers’ toughest challenges while giving them tremendous opportunities to grow their businesses,” said Cathleen Hess, global product director, Sabic Innovative Plastics. “Relationships with industry leaders such as Vaupell ensure that these materials meet the specific requirements of our customers and deliver measurable value. We’re taking another technological leap forward with these innovative new carbon-fibre-filled Ultem resins, to help global OEMs usher in a new era of cost-effective and lighter weight aircraft design.”

“Working closely with Sabic Innovative Plastics, we immediately saw the potential of carbon-fiber-filled Ultem resin to replace aluminium in interior aircraft applications,” said Mike Hamm, vice president, Sales, Vaupell.

Building upon Ultem resin’s capabilities for aircraft interiors, carbon-fibre-filled Ultem resin complies with FAA flammability FAR 25.85, smoke density and heat release requirements for OSU 65/65. In addition to tray table arms, potential applications for the new carbon-fiber-filled Ultem grades include armrests, footrests and galley items such as coffee maker chassis. Vaupell will conduct further load capability testing and fatigue testing later this year.
