Carbon fiber, PEEK combine in lightweight aerospace composite


Weight reduction and lean manufacturing are key focuses in the aerospace sector as designers seek to the reduce operating costs of their aircraft. Consequently, thermoplastic composites that can perform with at least the same assurance as traditional metals and thermosets are in demand.

In response to these requirements, Tri-Mack Plastics Manufacturing Corporation, a molder of high-temperature engineering thermoplastics located in Bristol, RI, has developed Victrex PEEK (polyetheretherketone) composite manufacturing capabilities and produced brackets for use in aircraft structural applications. The brackets weigh approximately 45g each, and are employed in primary and secondary structural applications in commercial and military aircraft. Tri-Mack specified the material due to its technical features and proven track record of 25 years of use in injection molded aerospace components....
