ANAHEIM, CALIF. — Culver City Composites Corp. has become the fourth and final licensee to make a new advanced resin designed to operate for long periods of time at 350F.

Peti-5 is an imide oligomer terminated with phenylethynyl groups. Peti-5 is tough, avoids microcracking, resists solvents, processes in a robust fashion and shows thermal stability, the firm said.

The National Aeronautics and Space Administration previously issued Peti-5 licenses to Imitec Inc. of Schenectady, N.Y.; Fiberite Inc.'s facility in Greenville, Texas; and Cytec Industries Inc.'s engineered materials unit in Havre de Grace, Md.

The addition to Culver City Composites' portfolio ``extends the horizons for our aerospace customers,'' said President Paul Pendorf. The Culver City, Calif., firm discussed its new license at SAMPE in Anaheim.

``This product has passed all requirements for NASA's high-speed civil transport program,'' said Jack Keating, Imitec vice president, but Peti-5 is not in service on any program.

A 60,000-hour — that's 6.8 years — test in a composite resin matrix began a year ago. Longer tests indicate Peti-5 has enormous strength in adhering titanium and also titanium honeycomb.
