Title:
METHOD FOR RECOVERING HIGH-PERFORMANCE CARBON FIBER FROM INORGANIC CEMENTING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/153217
Kind Code:
A1
Abstract:
A method for recovering high-performance carbon fiber from an inorganic cementing material, comprising the following steps: (A) placing a carbon fiber-reinforced inorganic (cement-based) composite material in an electrolyte at a reaction temperature of 25°C-75°C, the electrolyte containing 0.5%-3% by weight percent of NaCl and 1.0 g/L-5 g/L of a catalyst; (B) energizing the carbon fiber-reinforced cement-based composite material placed in the electrolyte, the carbon fiber reinforced cement-based composite material connecting to a positive electrode of a power source, and controlling the current density to be 3333.3-6666.7 mA/m2; and (C) after reacting by energizing for 0.5-200 hours, extracting a produced carbon fiber recovered product from the electrolyte.
