ABSTRACT Carbon fiber–reinforced polymer (CFRP) was prepared from carbon fiber (CF) sheet with a diacylhydrazine‐crosslinked matrix polymer, which is stable to natural stimuli, including heat and oxygen, but rapidly decrosslinks and dissolves when treated with sodium hypochlorite solution. The CF sheet was recovered without damage when the CFRP plate was treated with sodium hypochlorite solution without a shearing force. The recovered CF sheet could be used directly to prepare the next CFRP, from which the CF sheet could be recovered again without any damage. Because high durability and stability are compatible with the present CFRP, the repetitive use of the CF sheet for CFRP is practicable.
