PREPREG, METHOD FOR PRODUCING SAME, AND SLIT TAPE PREPREG

摘要

The invention aims to provide a prepreg that has excellent processability and handleability and can be processed into a cured product with high heat resistance and to provide a method to produce such a prepreg in an industrially advantageous way without being restricted by the types and contents of the matrix resin components used. The prepreg includes at least components [A] to [D] as given below and a preliminary reaction product that is a reaction product of the component [B] and the component [C], at least one surface resin in the prepreg having a storage elastic modulus G' in the range of 1.0 × 10sup3/supto 2.0 × 10sup8/supPa as measured at a temperature of 40°C and an angular frequency in the range of 0.06 to 314 rad/s: [A] carbon fiber, [B] epoxy resin, [C] curing agent, and [D] thermoplastic resin.
