A process to reclaim carbon fiber from a cured thermoset matrix comprising: adding the cured thermoset polyester or vinyl ester or polyurethane or epoxy matrix to a polyol solvent composition under conditions to free more than 97% by weight of the carbon fiber from the cured thermoset matrix, wherein the polyol solvent composition is selected from a group consisting of monosaccharides, disaccharides, sugar alcohols, ethylene glycol, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, ethylene glycol monobutyl ether, diethylene glycol, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol dimethyl ether, diethylene glycol diethyl ether, diethylene glycol monopropyl ether, diethylene glycol monobutyl ether, triethylene glycol, triethylene glycol monomethyl ether, triethylene glycol monoethyl ether, tetraethylene glycol, 1,2-propanediol, 1,3-propanediol, 1,2-butanediol, 1,3-butanediol, 1,4-butanediol, 2,3-butanediol, 1,5-pentanediol, glycerol, or dipropylene glycol; and wherein said conditions comprise an inert gas blanket and/or comprise adding co-reactants selected from a group consisting of hydroxides, carbonates, hydrogen carbonates and phosphates of alkali metals such as sodium carbonate, sodium hydroxide, sodium hydrogen carbonate, potassium hydroxide, potassium carbonate, potassium hydrogen carbonate, tripotassium phosphate, or a combination thereof; washing the carbon fiber with water; and drying the carbon fiber to reclaim the carbon fiber and wherein more than 99% by weight of the carbon fiber is reclaimed; and wherein said conditions comprise a constant temperature of between 125 and 250 degrees Celsius. adding the cured thermoset polyester or vinyl ester or polyurethane or epoxy matrix to a polyol solvent composition under conditions to free more than 97% by weight of the carbon fiber from the cured thermoset matrix, wherein the polyol solvent composition is selected from a group consisting of monosaccharides, disaccharides, sugar alcohols, ethylene glycol, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, ethylene glycol monobutyl ether, diethylene glycol, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol dimethyl ether, diethylene glycol diethyl ether, diethylene glycol monopropyl ether, diethylene glycol monobutyl ether, triethylene glycol, triethylene glycol monomethyl ether, triethylene glycol monoethyl ether, tetraethylene glycol, 1,2-propanediol, 1,3-propanediol, 1,2-butanediol, 1,3-butanediol, 1,4-butanediol, 2,3-butanediol, 1,5-pentanediol, glycerol, or dipropylene glycol; and wherein said conditions comprise an inert gas blanket and/or comprise adding co-reactants selected from a group consisting of hydroxides, carbonates, hydrogen carbonates and phosphates of alkali metals such as sodium carbonate, sodium hydroxide, sodium hydrogen carbonate, potassium hydroxide, potassium carbonate, potassium hydrogen carbonate, tripotassium phosphate, or a combination thereof; washing the carbon fiber with water; and drying the carbon fiber to reclaim the carbon fiber and wherein more than 99% by weight of the carbon fiber is reclaimed; and wherein said conditions comprise a constant temperature of between 125 and 250 degrees Celsius.
