摘要

An in-situ polymerized type thermoplastic prepreg is provided, which is excellent in productivity, has tack properties and drape properties that allow easy shaping in a mold, is excellent in handling properties, and allows a molded product obtained by curing to have both mechanical properties as high as those of a thermosetting composite and the features of the thermoplastic composite. An in-situ polymerized type thermoplastic prepreg 1 includes reinforcing fibers 2 and an in-situ polymerized type thermoplastic epoxy resin 3 as a matrix resin. The in-situ polymerized type thermoplastic epoxy resin 3 is cured to B-stage, with the weight-average molecular weight being 6,000 or less, and has tack properties and drape properties at 30° C. or less, and the in-situ polymerized type thermoplastic epoxy resin after curing has a weight-average molecular weight of 30,000 or more.
