摘要
PROBLEM TO BE SOLVED: To provide an epoxy resin composition which achieves the toughness of its cured product and which is more improved in adhesion workability than a conventional epoxy resin composition that has the same PES ratio as the epoxy resin composition and that is obtained by blending the cured product after dissolving an epoxy resin and PES.;SOLUTION: In the epoxy resin composition having the epoxy resin, the curing agent and polyethersulfone, the mass ratio of the epoxy resin to the polyethersulfone is 80:20 to 40:60. The epoxy resin composition is a liquid composition 1 in which solid particle-type polyethersulfone 3 is dispersed in a liquid epoxy resin 2. Moreover, in a cured product 10 obtained by curing the liquid composition, polyethersulfone serves as a matrix 11. The cured product 10 takes on a matrix-domain phase structure in which a domain 12 of the epoxy resin is dispersed in the matrix 11.;COPYRIGHT: (C)2012,JPO&INPIT
