Aromatic polyimide powder for molded body, molded body using same, method for improving mechanical strength of molded body

An aromatic polyimide powder for a molded body, wherein a volatile matter content contained in the aromatic polyimide powder is 1.03 to 5.00% by mass relative to 100% by mass of the aromatic polyimide powder of 25° C., and when molded, the aromatic polyimide powder provides an aromatic polyimide molded body having a flexural strength of 60 MPa or more, wherein the aromatic polyimide molded body is obtained by uniaxially pressing the aromatic polyimide powder at a pressure of 6000 kgf/cm2 at room temperature and pressureless firing an obtained uniaxially pressed body under atmospheric air at a temperature of 400° C. without going through a heating and compressing process of simultaneously applying pressure and heat, wherein the aromatic polyimide powder comprises an aromatic polyimide containing a unit derived from 2,3,3′,4′-biphenyltetracarboxylic dianhydride.
