What is Diamond Down?

Diamond Down is a prepreg “soft composite” fabric designed for applications beyond the industries current rigid and hard composite parts: a new perspective and a new way to build composite parts that retains all the structural characteristics of the composite materials, but in a soft and flexible form.

Carbon fiber, glass, and Kevlar are infused with a special compound making the fabric usable for building “soft composite” parts and products. Learn more about this new flexible perspective on composite building materials at JEC World 2026.

Currently, there are no composite fabrics designed for upholstery or soft-touch surfaces in hypercars or high-performance aircraft, so these carbon-fiber–intensive vehicles could use Diamond Down to increase their carbon intensity for consumer pleasure.

Likewise, there are no luxury fabrics that are not derived from animals. Composite materials—highly valued for their performance and prestige—could fulfill the desire for luxurious, rare, and sensually pleasing soft materials that rival leather in both appearance and can serve in any application where leather is used today: upholstery, vehicle interiors, handbags, wallets, watchbands and beyond. Soft composite fabrics can function not only as surface coverings for rigid frameworks but also as structural materials in their own right—offering the same performance advantages that composites provide to rigid parts.

I developed a pre-preg carbon fiber fabric made from the same materials used in the composite industry to produce rigid carbon fiber components. This fabric consists of raw carbon fiber impregnated with a compound that preserves the fiber’s inherent properties while remaining soft and flexible in its finished state. It also functions like a traditional prepreg, suitable for layering into more complex composite structures. The same design principles used for rigid components can be applied to soft ones: core materials, hard points, internal structures, and built-in rigidity can all be incorporated into a soft composite part.

1. Target Market and Customers: Our target customers are manufacturers of hypercars and high-performance personal aircraft seeking innovative, lightweight, and luxurious interior materials. Ideal partners include Koenigsegg, McLaren, Mercedes-AMG, and JMB Aircraft. These companies rely heavily on carbon fiber composites yet still depend on leather and other animal-sourced materials for soft-touch surfaces. Our soft composite fabrics offer a seamless extension of their structural material philosophy into the cabin—combining performance, beauty, and sustainability. Beyond interiors, bespoke applications such as luggage, seating, and accent panels offer new aesthetic and branding opportunities consistent with the exclusivity of the high-performance market.

2. Business Model and Go-To Market Strategy: With initial funding, we will build a custom manufacturing line modeled after industry-standard prepreg equipment to produce soft composite fabric at scale. Revenue will come from direct material sales and a training partnership program with high-performance vehicle or aircraft manufacturers. Through this program, we will collaborate with interior design teams to demonstrate fabrication techniques—embedding hard points, magnets, wiring, or lighting within soft composite parts. Each collaboration will be video-documented and edited into marketing content to attract future partners. The first projects will target hypercar brands such as Koenigsegg, McLaren, and Mercedes-AMG, as well as premium aircraft manufacturers like JMB Aircraft. These partnerships will showcase the fabric’s unique blend of luxury, structural performance, and sustainability, establishing our company as the leader in soft composite innovation for high-end mobility interiors.

3. Competitive Advantage/Market Disruption Potential of the Solution: Previous attempts to create soft composite fabrics have failed to achieve both functionality and luxury. Companies, such as Carbitex, developed promising materials, but these proved too stiff and lacked the refinement demanded by high-end interiors. Our innovation overcomes this barrier with a proprietary compound that preserves carbon fiber’s strength while maintaining true softness, flexibility, and visual allure. Beyond disrupting existing markets, it creates entirely new ones—inviting designers and engineers to imagine fresh applications across industries such as consumer electronics and robotics. This fabric becomes a catalyst for creativity, expanding where and how composites can be used.

4. Industrial or Economic Impact on the Composites Industry: This innovation broadens the very definition of composite materials. By introducing a true soft composite, we expand the industry’s creative and structural spectrum—from rigid to semi-rigid to flexible parts. This enables new design and manufacturing processes that invite collaboration between traditional composite engineers, designers, and new industries such as fashion, robotics, and consumer products. The economic impact lies not in lowering costs but in expanding opportunity—opening new markets, new partnerships, and new categories of products. It transforms composites from a niche structural solution into a versatile creative medium capable of shaping how the world builds and feels.

5. Environmental or Sustainability benefits: Our soft composite fabric offers a responsible alternative for industries and consumers who value luxury without ethical compromise. While not designed to replace leather entirely, it provides an option for those concerned about the environmental and animal-welfare costs of traditional sourcing in high-end fashion. Produced through a synthetic process already demonstrated as sustainable—such as carbon fiber manufacturing at BMW’s Moses Lake facility powered by 100% renewable energy—our material aligns performance and ethics. It expands the composite industry’s reach into a softer, more humane aesthetic space, proving that innovation and compassion can share the same texture.

6. Project Milestones for 12-24 months:

1. Within the first year, we will finalize our proprietary compounding process and design a scalable manufacturing system for Diamond Down fabrics. Our goal is to produce consistent pre-preg soft composite material in pilot quantities and deliver the first demonstrator interior—ideally through a partnership with a leading hypercar manufacturer such as Koenigsegg or McLaren.
   During months 12–18, we will publish initial engineering specifications for soft composite parts and launch a pilot training program for engineers and fabricators. This curriculum will link design software to practical building methods, ensuring accurate translation from model to material.
   By month 24, we aim to secure investment for a dedicated production facility in Oregon, capable of supporting both domestic and international collaborations. Each partnership will integrate a hands-on training component, fostering a global network of designers and builders who understand—and expand—the possibilities of soft composite construction.

2. In the next two years, we will establish scalable manufacturing for Diamond Down fabrics, beginning pilot production and securing our first automotive interior partnership—ideally with a leading hypercar manufacturer. Through these collaborations, we will refine material processes and engineering specifications while developing a comprehensive training program for soft composite fabrication. This program will evolve into a dedicated trade curriculum, bridging the gap between design software and real-world construction techniques. With investment, we plan to establish a production facility in Oregon and expand internationally through on-site collaborations that combine product integration, knowledge exchange, and hands-on innovation.
