Arrow McLaren and Greene Tweed have co-engineered a lightweight anti-roll bar lever for INDYCAR race cars using Greene Tweed's Xycomp DLF thermoplastic composite. The redesigned suspension component reduces weight by 64 grams per car whilst maintaining strength and reliability required for elite racing. The component, which helps control chassis roll during high-speed cornering, was transitioned from 7075 aluminium billet to the thermoplastic composite material. Greene Tweed worked closely with Arrow McLaren's engineering team to evaluate performance requirements, geometry and manufacturing approaches. The new anti-roll bar levers were first introduced on Nolan Siegel's No. 6 car at Barber Motorsports Park and have since been implemented across all Arrow McLaren vehicles. The project also reduced internal development workload for Arrow McLaren's engineering and production teams.
Greene Tweed accelerates customer innovation with rapid prototyping capability for thermoplastic composites. New process cuts prototype lead times in half, helping customers move faster from concept to testing LANSDALE, PA, UNITED STATES, June 25, 2026 / EINPresswire.com / - Greene Tweed, a global leader in advanced materials and high-performance solutions, has developed a rapid prototyping process for its Xycomp(R) DLF(TM) material that helps aerospace customers accelerate metal replacement development projects through faster testing and validation. The process significantly reduces lead times and costs, expanding access to high-performance composites in new markets, including Advanced Air Mobility (AAM) and Defense. Xycomp (R) DLF(TM) components are high-performance thermoplastic composites engineered to replace metals while delivering weight savings, stiffness, and strength. The new process cuts prototype lead times by nearly 50% compared to traditional production methods through a proprietary approach that optimizes the tool design and balance between machine and net-molded features, while maintaining production-representative material and part properties. The result is quicker access to functional parts, with lower upfront tooling costs and greater design flexibility before production. "Greene Tweed recognized the need for a faster, more cost-effective way to support the development of lightweight, high-performance components for customers," said George Rawa, General Manager, Structural & Engineered Components at Greene Tweed. "This process expedites the timeline to evaluate Xycomp composites in real-world applications by putting production-quality parts in engineers' hands in a fraction of the time." Key innovations behind Greene Tweed's rapid prototyping breakthrough include: Optimized Mold Design: A balance of machined and net-molded features reduces tooling complexity and speeds up production. Streamlined Parallel Processes: Completing part, tool, and fixture designs concurrently significantly compresses timelines. In-House Expertise: A hands-on approach ensures precision and quality, with mold fit-ups completed in one to two days. Rapid, Low-Cost Iteration: Customers can test, refine, and optimize components through phased evaluations with lower cost, readily modifiable tools. Rapid prototyping is helping expand composite adoption across aerospace, AAM, defense, mobile robotics, and energy as demand grows for lightweight, durable components. In AAM, customers are using Xycomp (R) DLF(TM) components for lightweight, custom-engineered electric vertical take-off and landing (eVTOL) applications, with rapid design iteration and close technical collaboration between customers and Greene Tweed engineers fast-tracking the path from concept to reality. Greene Tweed representatives will be available at the Farnborough Air Show 2026 (Hall 0, Booth #0640) to discuss Xycomp (R) DLF(TM) and metal replacement opportunities; attendees can register here to schedule a meeting. Greene Tweed will also host the webinar, "Solving Aerospace Weight and Prototype Bottlenecks with Xycomp (R) Thermoplastic Composite Components," on September 30, 2026. Register here to attend.

The inside story on aerospace thermoplastic composites. Sponsored by: As aerospace and defense platforms face tighter space and weight constraints, power limitations, and increasingly high operating temperatures, engineers are turning to passive temperature control solutions that reduce system complexity and failure points. Thermally actuated valves use temperature driven actuation to control flow within a system. Glenn Quinty, Senior Engineering Product Specialist at ThermOmegaTech, explains how thermal actuation works, why it excels in SWaP constrained systems, and where these solutions are deployed. Don't have an account? Overview. The document presents an interview with Travis Mease, Thermoplastics Product Manager at Greene Tweed, discussing Xycomp(R) DLF(TM), a lightweight, high-performance thermoplastic composite developed for aerospace applications. With over 80 years of industry expertise, Greene Tweed created DLF composites using aerospace-grade carbon-fiber prepreg tape to replace metal components, delivering up to 60 percent weight savings and currently having over 500,000 parts in service. A key advantage of Xycomp(R) DLF(TM) is its highly automated compression molding process, which supports complex geometries and high-volume production with minimal operator interaction. Automation includes material charge weighing, mold handling, automatic fiber placement reinforcement, mold release, and robotic deburring. This process achieves high-quality parts meeting GD&T standards with increased throughput, repeatability, and cost competitiveness. Compared to aluminum parts, DLF composites offer 30 to 50 percent weight savings while maintaining cost-effectiveness relative to machined metal parts. DLF composites bridge the performance gap between injection molding (high shape complexity, low mechanical strength) and continuous fiber composites (high strength, but limited out-of-plane design freedom). Importantly, DLF composites maintain stability and strength at elevated temperatures up to at least 180 °C, outperforming aerospace-grade aluminum alloys vulnerable to heat-induced strength reduction. In some cases, DLF has replaced titanium or steel, yielding even greater weight savings. A specific use case highlighted is the business jet outer guide vane, a complex, non-structural part subjected to hail impact and durability requirements. Greene Tweed developed a co-molding technique combining a metallic leading edge with a net-molded DLF vane, validated through hail impact testing in Switzerland. This hybrid vane delivers substantial weight reductions of eight to 10 pounds per engine in a cost-effective manner. Regarding certification challenges, Mease notes that new aerospace materials require extensive characterization to meet strict regulatory demands. Greene Tweed leverages industry-accepted materials and comprehensive testing - covering various environmental conditions, loading scenarios, material batches, and part thicknesses - to build a large database of material properties. This data supports predictive design analysis and provides customers with validated allowables, accelerating certification, reducing risk, shortening timelines, and lowering costs. Overall, Greene Tweed's Xycomp(R) DLF(TM) presents a high-performance, lightweight thermoplastic composite solution for advanced aerospace manufacturing, balancing design flexibility, mechanical performance, and regulatory compliance.
