| titleOfInvention | Prepreg, method for producing the same, and carbon fiber reinforced composite material |
| abstract | [Problem] To provide a prepreg that has fast curing properties and has few carbon fiber single yarn fluffs on the surface of a molded article at the same time, is excellent in design properties, and has good appearance quality even during clear coating. SOLUTION: Carbon fibers having a knot bundle strength of 100 to 600 MPa and a ratio of a major axis to a minor axis of a single yarn of 1.10 to 1.30 have a minimum viscosity at 90 to 115 ° C. of 1.0. A prepreg impregnated with a matrix resin having a curing time of 1 to 5 minutes when the prepreg is heated at 150 ° C. and having a width of 5 μm or more on the prepreg surface In addition, the number of single yarn fluff having a length of 5 mm or more is 50 / m 2 or less, the flow rate of the matrix resin is 10 to 20% by mass, and the maximum cross-sectional height Rt of the surface of the prepreg is 80 μm or less. Prepreg. [Selection] Figure 3 |
