VICTREX® PEEK™ Polymer Offers Efficiency and Processing Improvements Versus Other Materials

Aerospace engineers want to specify materials that can withstand harsh environments, reduce manufacturing costs and offer processing flexibility. As a lightweight solution, VICTREX PEEK resins, composites, films, tapes and coatings have successfully displaced metals, traditional composites and other plastics in a growing number of aerospace applications because they are exceptionally strong, inert, inherently flame retardant, and can be easily fabricated into tight tolerance parts.

VICTREX PEEK polymer, APTIV™ film and VICOTE® coatings are engineering plastics well-suited for exterior applications where contact occurs with atmospheric particulates and chemicals. Interior applications demand the durability, flammability and low smoke toxicity properties of Victrex's high performance polymers.

VICTREX PEEK polymers are successfully used in a variety of forms (powder, film, filament) as a matrix material in the manufacture of advanced thermoplastic composite prepregs made of carbon, glass or aramid continuous fibers. VICTREX PEEK polymers are engineered to provide optimum impregnation of the reinforcing fibers and fiber-matrix interface.

The use of lightweight composite materials in new airplane structures is becoming standard, however, joining these structures is too often done with standard metal fastening systems that add unwanted weight. VICTREX PEEK composite material is an excellent substitute for metals and thermoset composites and provides the added benefit of lightweight fastening systems, bolts, nuts, inserts and brackets.

VICTREX PEEK polymers have been officially qualified by many aircraft manufacturers and can also be supplied to the military specification MIL-P-46183.

All of these polymeric advantages translate to improved efficiencies both in terms of aircraft weight, but also ease of manufacturing by combining several components into a single part with better uniformity. Lightweight components mean easier assembly for manufacturers and overall reductions in aircraft operating costs.
