PROBLEM TO BE SOLVED: To provide a tow prepreg excellent in unwindability from a spool, process passing property in a filament winding process and shape retention property and having resin flow during curing and a (fiber reinforced) composite material pressure container obtained by using the same and high in tank burst pressure.SOLUTION: There is provided a tow prepreg by impregnating a reinforced fiber bundle with a matrix resin composition containing following component (A), component (B), component (C1) and component (C2). Component (A): an epoxy resin. Component (B): an epoxy resin curing agent. Component (C1): a pre-gelling agent particle. Component (C2): a lysate of a pre-gelling agent particle, where the pre-gelling agent particle may be same as or different from the component (C1).SELECTED DRAWING: None |
