Tape-shaped prepreg and fiber-reinforced molded object

1:

• A tape-shaped prepreg, comprising:
• a plurality of unidirectionally oriented fibers and
• a binder infiltrated into these fibers,
• wherein
• the tape-shaped prepreg has an average thickness of 50 μm to 150 μm;
• a content percentage of the plurality of fibers in the tape-shaped prepreg is 30 vol % to 60 vol %;
• a fractal dimension D of a coefficient of variation Cv(n), which is determined from an areal proportion a of fibers in each of regions obtained by equally dividing a cross-sectional image perpendicular to an orientation direction of the plurality of fibers into n sections, where n is an integer of 2 or larger, along each of lengthwise and crosswise directions, is 0.4 to 1.5;
• and
• a degree of orientation P, which is expressed by equation (1):
• Degree of orientation P=1−((minor-axis length of approximate ellipse)/(major-axis length thereof)) equation (1), and
• determined from an approximate ellipse of a power-spectrum image obtained by Fourier transform of a cross-sectional image parallel to the orientation direction of the plurality of fibers, is 0.8 or greater and less than 1.0.
