摘要

(57) Abstract It is something regarding the strengthening fiber where this invention coating did the coat membrane of the thermal decomposition characteristic binder in the core section, for example uses for the fiber reinforced composite material and the like. At the time of this inventing, with the core section and the coat membrane, it tried to form the coat layer which consists of thermal decomposition formation carbon or hydrous carbon. This invention furthermore is something regarding the fiber reinforced composite material which is produced making use of the fiber strand, formed this coat layer the fiber strand, and this strengthening fiber or the fiber strand which consist of this strengthening fiber furthermore, is this strengthening fiber and something regarding the production method of the composite material.
