Nonwoven fabrics – Innovative Breakthrough: Toray Unveils Carbon Fiber Recycling Technology That Preserves Strength and Surface Quality While Enabling Circular Economy Transformation 03-11-2025
Nonwoven fabrics : Introduction
In a major materials-innovation step, Toray Industries, Inc. has developed a recycling technology for carbon-fiber-reinforced plastics (CFRP) that remarkably maintains strength and surface quality of recycled carbon fibers. The advancement opens new pathways into nonwoven fabrics and industry-wide reuse across sectors like automotive, construction and electronics.
What the technology does
Traditional methods for recycling CFRP face hurdles: thermosetting resins are highly cross-linked and difficult to break down; fibers often suffer thermal damage; and resin residues hamper reuse. Toray overcame these issues by creating a decomposition agent that breaks down three-dimensionally cross-linked thermosetting resins at lower temperatures than conventional methods.
As a result, recycled carbon fiber retains over 95 % of the single-fiber tensile strength compared to virgin petroleum-derived carbon fiber. chemxplore.com The process also leads to significantly less carbon-dioxide emissions — less than half the amount generated by manufacturing virgin carbon fiber.

Why this matters
Maintaining high fiber strength and surface quality is critical for advanced applications. With this technology, recycled carbon fiber shows minimal fiber breakage, low resin residue, and an excellent surface condition — all of which enable processing into finer formats, including sheet-form nonwoven fabrics.

The result: recycled carbon fiber that does not just match but exceeds conventional recycled counterparts in performance and versatility. This opens the door to wider industrial adoption of recycled carbon fiber and supports a circular economy in advanced materials.
New material form: nonwoven fabrics
Toray successfully processed the recycled fibers into a nonwoven fabric, leveraging controllable water dispersibility and uniform sheet-forming. These nonwovens combine carbon fiber functionality (such as radio-frequency shielding and thermal conductivity) with aesthetic qualities reminiscent of traditional Japanese paper (washi).
These fabrics are suitable for applications ranging from automotive interiors to exterior parts, construction elements, electronics housings and even consumer daily-use items — broadening the horizon for recycled carbon fiber beyond traditional high-end industries. Nonwoven fabrics
Prototype & applications underway
Toray has begun providing prototype samples of the recycled carbon fiber and nonwoven fabrics to customers in the automobile, building, electronics and daily-necessities sectors for technical assessment and development. TORAY United States+1
A standout demonstration: a concept car by Mazda Motor Corporation will showcase interior and exterior components made with these recycled‐carbon-fiber nonwovens at the Japan Mobility Show in Tokyo.
Strategic significance and sustainability alignment
This initiative is part of Toray’s participation in a program run by the Ministry of the Environment (Japan) for fiscal years 2024 through 2025 aimed at establishing a decarbonised and circular economy.
Within the Toray Group Sustainability Vision for 2050, a key goal is to contribute to a world where resources are sustainably managed. This new recycling process embodies that vision by turning advanced carbon fiber waste into high-value, reusable material.
Take-aways for industry
-
The ability to retain over 95 % of fiber strength means recycled carbon fiber can be used in high-performance roles.
-
Low thermal damage and low resin residue reduce processing challenges and broaden materials compatibility.
-
The nonwoven format opens up new design and application routes, including aesthetic and functional demands.
-
By reducing CO₂ emissions compared to virgin carbon fiber manufacturing, the technology supports decarbonisation and sustainability goals.
Conclusion
Toray’s recycling innovation marks a significant shift in how carbon-fiber-reinforced plastics (CFRP) can be managed end-to-end. By enabling high-quality recycled carbon fiber and imaginative nonwoven materials, this technology brings advanced materials into the circular economy in a meaningful way. As industry partners engage with prototypes and new applications emerge in automotive, construction, electronics and consumer goods, the moment for recycled carbon fiber is clearly upon us.
