Beschreibung
Zusammenfassung:	An epoxy resin composition suitable as a matrix resin for fiber reinforcement; and a yarn prepreg which has an excellent high-order processability by virtue of suitable unwindability and drapeability and a high degree of development of tensile strength and reinforced fiber strength after the curing of the epoxy resin. The yarn prepreg is characterized in that the weight content Wf (%) of fiber bundles, the number F of filaments in the fiber bundles, and the prepreg width d (mm) satisfy the following relationships: (1) 50 Wf 80; (2) 20000 F 100000; (3) F/8000 d F/2400. The epoxy resin composition comprises the following components: ¢A! an epoxy resin blend having an epoxy equivalent of 210 to 370, comprising a mono- or difunctional epoxy resin and a tri- or higher polyfunctional epoxy resin in respective particular amounts; ¢B! fine particles which contain a rubber component and are insoluble in the epoxy resins; and ¢C! a curing agent.
