To its line of high-performance, thin-gauge sheet materials, Ensinger’s PennFibre Division (Bensalem, Pa.) has added glass fiber-reinforced polyetheretherketone (PEEK) that meets the ASTM D6262 standard. By adding glass reinforcement to its thin-gauge TECAPEEK GF30 sheet, the manufacturer says it has dramatically improved properties at higher temperatures. At 250°C/482°F, the modulus maintains 30 percent of its ambient stiffness at 435 kpsi, and it retains about half its room-temperature flexural strength (10,150 kpsi). The company also reports that it may now be possible to manufacture truly structural thermoformed parts that can operate at 260°C/500°F continuously (100,000 hours). Possible applications include fuel cells, ducting, manifolds and canisters used in heavy trucks and buses, aircraft, trains and marine environments.
