Document Type and Number:
WIPO Patent Application WO/2017/208605
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a prepreg sheet including a radical-polymerizable resin composition, the prepreg sheet giving FRPs that have excellent mechanical properties and being excellent in terms of curability and storability. The prepreg sheet of the present invention is obtained by infiltrating a radical-polymerizable resin composition into fibers, and is characterized in that the radical-polymerizable resin composition contains at least a urethane (meth)acrylate compound (a) represented by the following [Chemical formula 1]. (In [Chemical formula 1], n is 2-100; X is a residue of a compound having two or more isocyanate groups; and the M moieties at least include [Chemical formula 2]: [Chemical formula 2] -N=C=O the remainder of the M moieties being [Chemical formula 3].
