SEMIPREG, PREPREG, RESIN COMPOSITE MATERIAL, AND PRODUCTION METHODS THEREOF

The purpose of the present invention is to achieve: a semipreg and a prepreg, each of which is capable of reducing the residual volatile content; respective production methods of the semipreg and the prepreg; a fiber reinforced composite material which is reduced in or becomes free from defects such as voids due to the semipreg or the prepreg, thereby having good heat resistance and mechanical strength; and a production method of the fiber reinforced composite material. The present invention solves the above-described problem by providing a semipreg or the like, which is characterized by containing a powder of an imide oligomer represented by specific general formula (1) and reinforcing fibers.
