PURPOSE:To obtain a polyimide resin compsn. having excellent heat resistance, dimensional stability, mechanical strength, etc., by blending a polyimide resin composed of a specified repeating unit with glass fiber. CONSTITUTION:A polyimide resin compsn. is obtd. by blending 100pts.wt. polyimide resin composed of a repeating unit of formula I with 5-100pts.wt. glass fiber. In the formula I, Y is a single bond or a group selected from the group consisting of a 1-10 C bivalent hydrocarbon, hexafluorinated isopropylidene, carbonyl, thio, sulfinyl, sulfonyl oxide groups; and R is a tetravalent group selected from the group consisting of a 2 C or higher aliph. group, an alicyclic group, a monocyclic group, a condensed polycyclic arom. group and a non- condensed cyclic arom. group, wherein arom. groups are linked with each other through a crosslinking member.
