- Toray developed a recycling technology for carbon fiber reinforced plastics using a new decomposition agent.
- The recycled carbon fiber retains over 95% of the tensile strength of virgin carbon fiber.
- Toray's technology reduces carbon dioxide emissions to less than half compared to virgin carbon fiber production.
- Mazda will showcase the recycled carbon fiber in a concept car at the Japan Mobility Show.
Recycling Technology Development
Toray Industries has developed a recycling technology capable of decomposing carbon fiber reinforced plastics (CFRP) made from thermosetting resins. This innovation retains the strength and surface quality of the fibers, allowing for the creation of nonwoven fabrics from recycled carbon fibers.
Prototype and Applications
Toray is providing prototype samples to customers for developing performance and decorative materials across various sectors, including automotive, construction, electronics, and daily necessities. The company is conducting technical assessments to align with customer needs.
Recycling Process and Benefits
The technology involves a decomposition agent that breaks down degradation-resistant, three-dimensionally crosslinked thermosetting resins at lower temperatures. This process retains over 95% of the tensile strength of virgin carbon fiber and reduces carbon dioxide emissions to less than half compared to traditional manufacturing methods.
Material Properties and Uses
The recycled carbon fiber is stronger than conventional counterparts, with minimal fiber breakage and low resin residue. It can be processed into sheet-form nonwoven fabrics, offering functionality like radio frequency shielding and thermal conductivity, combined with aesthetic qualities reminiscent of traditional Japanese paper.
Industry Collaboration
The innovative fabric will feature in the interior and exterior components of a concept car by Mazda Motor Corporation, showcased at the Japan Mobility Show. Toray's development aligns with a Ministry of the Environment program promoting a decarbonized and circular economy.
