| titleOfInvention | Prepreg and manufacturing method thereof |
| abstract | An object of the present invention is to provide a prepreg having a low resin content and a low fiber basis weight which is excellent in openness of continuous fibers, does not cause excessive resin overflow, has good tackiness, has no cracks, and has good quality. A carbon fiber having a tensile modulus of 270 GPa or more, a number of filaments of 3000 to 12000, and 0.8 to 2.2% by mass of a sizing agent containing a bisphenol A type epoxy resin as an essential component, and a specification A prepreg comprising a thermosetting resin having a minimum viscosity of 0.5 to 5 Pa ยท s measured by the method described in the manual, wherein the mass of the carbon fiber per unit area of the prepreg is 25 to 40 g / m 2 , resin mass content is 15 to 25%, width is 500 mm or more, release paper is provided on at least one surface, single fiber cross-sectional diameter ratio of predetermined carbon fiber, maximum cross-sectional height of predetermined prepreg surface A prepreg having a thickness Rt, a tack on both surfaces of a predetermined prepreg, a peel strength between the predetermined prepreg and the release paper, and a predetermined number of cracks and fluffs. [Selection figure] None |
