EPOXY RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL, YARN PREPREG, AND PROCESS AND APPARATUS FOR PREPARING THE SAME

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...

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
