Greene Tweed cuts composite prototype lead times in half

Greene Tweed has introduced a rapid prototyping process for its Xycomp DLF thermoplastic composites, aiming to help aerospace and defense customers move faster from concept to testing. The company says the process can reduce prototype lead times by nearly 50% and lower upfront tooling costs as demand grows for lightweight metal replacement parts.

Why it matters: - Greene Tweed’s new prototyping process could speed up development of lightweight composite parts for aerospace, Advanced Air Mobility, defense and other markets. - Faster prototypes can shorten the path from design concept to testing and validation. - Lower tooling costs may make high-performance thermoplastic composites easier to adopt in new applications.

What happened: - Greene Tweed developed a rapid prototyping process for its Xycomp® DLF™ material. - The process is designed to help customers accelerate metal replacement development projects. - The company says the method cuts prototype lead times by nearly 50% versus traditional production methods. - Greene Tweed said the process also lowers costs and expands access to high-performance composites in new markets.

The details: - Xycomp® DLF™ components are thermoplastic composites engineered to replace metal while delivering weight savings, stiffness and strength. - The process uses a proprietary approach that balances machine features with net-molded features. - Greene Tweed says the approach keeps production-representative material and part properties. - The company says the method delivers functional parts faster, with lower upfront tooling costs and more design flexibility before production. - George Rawa, general manager of structural and engineered components at Greene Tweed, said the process gives engineers production-quality parts in a fraction of the time. - Greene Tweed says the key innovations include optimized mold design, parallel part-tool-fixture design work, in-house mold fit-ups completed in one to two days, and low-cost iterative testing with modifiable tools. - The company says rapid prototyping is helping expand composite adoption across aerospace, AAM, defense, mobile robotics and energy. - In AAM, customers are using Xycomp® DLF™ components for custom-engineered eVTOL applications. - Greene Tweed says close technical collaboration with customers is speeding design iteration. - Greene Tweed’s website is more information.

Between the lines: - The announcement points to a broader push to replace metal parts with composites where weight reduction and stiffness matter. - Faster prototyping can be especially valuable in aerospace and eVTOL development, where iteration cycles are often expensive and slow. - The process also suggests Greene Tweed is trying to reduce one of the main barriers to composite adoption: tooling time and cost before full production.

What’s next: - Greene Tweed representatives will discuss Xycomp® DLF™ and metal replacement opportunities at the Farnborough Air Show 2026 in Hall 0, Booth #0640. - The company will host a webinar, “Solving Aerospace Weight and Prototype Bottlenecks with Xycomp® Thermoplastic Composite Components,” on Sept. 30, 2026. - Attendees can register to schedule a meeting at the air show. - Greene Tweed also plans to use the webinar to explain the composite prototyping approach and its aerospace applications.

The bottom line: - Greene Tweed is trying to make advanced composites faster and cheaper to prototype, which could widen their use in aerospace and next-generation aircraft programs.
