Carbon Fiber Composite brackets made from VICTREX® PEEK polymer reduce fuel costs on next generation aircraft

09/30/2014 | News in  General

PARIS, FRANCE – (March 12, 2013) – With the aerospace industry focusing on reducing aircraft weight and lean manufacturing, engineers are searching for reliable solutions such as thermoplastic composites that can perform with at least the same assurance as traditional metals and thermosets. In response to these requirements, Tri-Mack Plastics Manufacturing Corporation, a molder of high temperature engineering thermoplastics located in Bristol, Rhode Island, has developed VICTREX® PEEK composite manufacturing capabilities and produced brackets for use in aircraft structural applications. As VICTREX PEEK polymers have been used in injection molded aerospace components for more than 25 years, Tri-Mack specified the material due to its excellent technical features and proven track record in the industry.

Based on current fuel prices and studies, the removal of 1 kilogram (2.2 pounds) of weight from a short-range aircraft can save airlines up to $100 in annual fuel costs. “Assuming that the composite brackets can remove 100 kilograms (220.5 pounds) of weight, an airline with 500 short-range aircraft could save up to $5 million per year in fuel costs by making the switch from metal,” explained Ralf Weidig, Composites Business Leader for Victrex.

Besides up to 70% weight savings compared to metals such as stainless steel, aluminum, and titanium, the innovative composite manufacturing process used by Tri-Mack provides several benefits leading to faster part manufacturing cycle times compared to thermosets. “Thermoset composite parts typically take several hours to complete,” said Tom Kneath, Director of Sales and Marketing at Tri-Mack. “The VICTREX PEEK thermoplastic composite brackets have manufacturing cycle times measured in minutes. That speed, paired with the ability to recycle the material for other applications, takes us to a whole new level of processing efficiency that isn’t achievable with thermosets.”

Component integrity is also critical to keeping aircraft in service in order to minimize maintenance and downtime. Thermoplastic composites made from VICTREX PEEK can provide the chemical and corrosion resistance to jet fuel, hydraulic fluid, de-icing solution, salt, steam, water and other commonly used service fluids that would typically undermine the longevity of metals. “VICTREX PEEK composites can offer between four and five times higher fatigue strength, specific stiffness, and specific strength when compared to traditional metals such as aluminum,” said Weidig. “These mechanical properties along with vibration and noise dampening improvements make VICTREX PEEK composites an attractive and viable solution for engineers looking to replace heavy metals and thermosets.”

Victrex will be showcasing the composite brackets at the upcoming JEC Europe show held in Paris, France on March 12-14, 2013. Visit booth J11 to understand the weight savings potential when replacing aluminum, titanium, and stainless steel with VICTREX PEEK composite brackets.
