REINFORCING ADHESIVE SHEETS

摘要

A reinforcing adhesive sheet (1) is described, comprising a thermosetting resin sheet-shaped prepreg (2) with a reinforcing material (3) embedded therein, and a flattened tubular material (4) provided on one side of the prepreg (2), said flattened tubular material (4) being capable of nearly recovering the original tubular form on heating and being narrower in width that the prepreg (2). The prepreg (2) may be of the two-layer structure comprising a first thermosetting resin composition layer (E) and a second thermosetting resin composition layer (G).
