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.
