摘要：
[1]一种聚酰亚胺树脂组合物，其含有聚酰亚胺树脂(A)和添加剂(B)，所述聚酰亚胺树脂(A)包含下述式(1)所示的重复结构单元和下述式(2)所示的重复结构单元，式(1)的重复结构单元相对于式(1)的重复结构单元和式(2)的重复结构单元的总和的含有比为40～70摩尔％；[2]一种复合材料，其是将聚酰亚胺树脂(A)浸渗于纤维材料(C)而得到的，所述聚酰亚胺树脂(A)包含下述式(1)所示的重复结构单元和下述式(2)所示的重复结构单元，式(1)的重复结构单元相对于式(1)的重复结构单元和式(2)的重复结构单元的总和的含有比为40～70摩尔％。(R1为包含至少1个脂环式烃结构的碳数6～22的二价基团。R2为碳数5～20的二价链状脂肪族基团。X1和X2分别独立地为包含至少1个芳香环的碳数6～22的四价基团。)
摘要（英）：

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.
