摘要：
The present invention relates to an extremely fatigue-resistant polyimide resin composition comprising 100 parts by weight of polyimide having from 0.5 (exclusive) to 1.0 (inclusive) mole ratio of recurring structural units represented by the formula (1)
and from 0 (inclusive) to 0.5 (exclusive) mole ratio of recurring structural units represented by the formula (2) :
wherein X is
in the formulas (1) and (2), and having an inherent viscosity of 0.45 dℓ /g or more ; and 5∼65 parts by weight of a carbon fiber, glass fiber, aromatic polyamide fiber and/or potassium titanate fiber, and an injection molded article made from the polyimide resin composition.
and from 0 (inclusive) to 0.5 (exclusive) mole ratio of recurring structural units represented by the formula (2) :
wherein X is
in the formulas (1) and (2), and having an inherent viscosity of 0.45 dℓ /g or more ; and 5∼65 parts by weight of a carbon fiber, glass fiber, aromatic polyamide fiber and/or potassium titanate fiber, and an injection molded article made from the polyimide resin composition.
