摘要： Provided are: a carbon fiber bundle which has a large value of single-fiber fineness and excellent productivity and which, despite this, contains few interlaced single fibers therein and has excellent spreadability; and precursor fibers which are suitable for use in producing the carbon fiber bundle. The precursor fibers are a carbon-fiber-precursor acrylic fiber bundle which comprises a polyacrylonitrile copolymer comprising 95-99 mol% acrylonitrile units and 1-5 mol% hydroxyalkyl (meth)acrylate units and which has a single-fiber fineness of 1.5-5.0 dtex. In the acrylic fiber bundle, the cross-section of each single fiber which is perpendicular to the fiber axis has a shape that has a roundness of 0.9 or less. The roundness is a value determined using equation (1) where S and L are the cross-sectional area and the circumferential length, respectively, of a single fiber which are obtained by examining, with an SEM, the cross-section of the single fiber which is perpendicular to the fiber axis and analyzing the obtained image. Roundness = 4pS/L 2 (1)

摘要： The present invention pertains to a prepreg containing reinforcing fibers and an epoxy resin composition. Said prepreg is sandwiched between dies preheated to 140.degree.C and pressurized to MPa and held for five minutes at this temperature to obtain a cured article having a G'Tg of at least 150.degree.C. The present invention also pertains to a fiber-reinforced composite material and a method for producing same. According to this invention, it is possible to provide a prepreg which is well suited to press-molding, particularly to high-cycle press-molding. It is also possible to provide a fiber-reinforced composite material which can be heat-cured at a lower temperature and over a shorter time than conventional methods, with which it is possible to minimize excessive flow of resin in hot-press curing, and which is resistant to performance defects such as fiber meandering and defects in surface appearance. A method for producing the same can also be provided.
