Recycling carbon technology that extracts carbon fibers from CFRP using electrolysis!
The "Electrolytic Oxidation Method" is a technology for recovering carbon fibers in fibrous form from carbon fiber reinforced plastic (CFRP) waste using electrolysis. Since it is a manufacturing method conducted in water, a slurry containing well-dispersed carbon fibers of several centimeters in length is obtained, from which a thin non-woven fabric with well-dispersed fibers can be produced using the papermaking method. The process is simple, does not require large-scale capital investment, has high productivity, and allows for the recovery of the matrix resin. 【Features】 ■ Technology for extracting carbon fibers from CFRP through electrolysis ■ The lowest manufacturing cost ■ Simple process ■ No need for large-scale capital investment ■ Recovery of matrix resin is also possible *For more details, please request materials or view the PDF data available for download.

Company information
Ai-Carbon Co., Ltd. is named after the initials of Advanced Innovative Carbon, and aims to contribute to various carbon material fields from a business perspective. An urgent issue that has emerged is the recycling of carbon fibers, which is rapidly expanding in the market. We aim to isolate and recover carbon fibers from carbon fiber reinforced plastics (CFRP), which are difficult to decompose and pose waste disposal problems, using an inexpensive electrolysis method for reuse.
