Document Type and Number:
Japanese Patent JP5780370
Kind Code:
B2
Abstract:
A polyimide resin composition containing a polyimide resin (A) and an additive (B), the polyimide resin (A) containing a repeating structural unit represented by the following formula (1) and a repeating structural unit represented by the following formula (2), a content ratio of the repeating structural unit of formula (1) with respect to the total of the repeating structural unit of formula (1) and the repeating structural unit of formula (2) being from 40 to 70 mol%; and [2] a composite material containing a fiber material (C) impregnated with a polyimide resin (A) containing a repeating structural unit represented by the following formula (1) and a repeating structural unit represented by the following formula (2), a content ratio of the repeating structural unit of formula (1) with respect to the total of the repeating structural unit of formula (1) and the repeating structural unit of formula (2) being from 40 to 70 mol%:
wherein R 1 represents a divalent group having from 6 to 22 carbon atoms containing at least one alicyclic hydrocarbon structure: R 2 represents a divalent chain aliphatic group having from 5 to 20 carbon atoms; and X 1 and X 2 each independently represent a tetravalent group having from 6 to 22 carbon atoms containing at least one aromatic ring.
