特に炭素繊維強化複合材料（以下ＣＦＲＰと略記する）
のマトリックス樹脂として有用なエポキシ樹脂組成物に
関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to fiber reinforced composite materials (hereinafter abbreviated as FRP),
In particular, carbon fiber reinforced composite materials (hereinafter abbreviated as CFRP)
The present invention relates to an epoxy resin composition useful as a matrix resin.
従来の技術
近年、ＦＲＰｌ特にＣＦＲＰはスポーツ・レジャー用品
や航空機の分野に広（使用されており、その需要も年々
増大している。BACKGROUND OF THE INVENTION In recent years, FRP, especially CFRP, has been widely used in the fields of sports and leisure goods and aircraft, and the demand for it is increasing year by year.
ＦＲＰ、ＣＦＲＰは一般に、ガラス繊維、アラミド繊維
、ボロンｍｉｉ、炭素繊維などのｔａ維基材にマトリッ
クス樹脂を含浸してプリプレグとなし、これらを積層し
て適当な温度で硬化させろことにより得られる。FRP and CFRP are generally obtained by impregnating a TA fiber base material such as glass fiber, aramid fiber, boron MII, or carbon fiber with a matrix resin to form a prepreg, and then laminating these prepregs and curing them at an appropriate temperature.

脂を用いることによりこれらの欠点を改良することが提
案されているが、反面マトリックス樹脂の伸びが減少し
、そのため耐熱衝撃性の低下が起こるという問題点を有
している。Epoxy resin, which has excellent adhesiveness to carbon fibers, is used as the matrix resin for CFRP. However, the bisphenol A type epoxy resins that have been mainly used heretofore have the drawbacks of poor heat resistance9 and also low composite physical properties, particularly low interlayer shear strength (hereinafter abbreviated as ILSS). On the other hand, it has been proposed to improve these drawbacks by using a multifunctional epoxy resin, but on the other hand, it has the problem that the elongation of the matrix resin decreases, resulting in a decrease in thermal shock resistance. .
