    摘要： The present invention relating to prepegs has the following constitution to achieve the above object. That is, a prepreg, comprising long reinforcing fibers [A], matrix resin [B] and a knitted fabric made from thermoplastic resin fibers [C], with the component [C] distributed near either or both of the surface layers. Moreover, the present invention relating to processes for production of prepregs has either of the following constitution to achieve the above object. That is, a process for preparing a prepreg, comprising the steps of impregnating long reinforcing fibers [A] with matrix resin [B], and bonding a knitted fabric made from thermoplastic resin fibers [C] onto one side or both sides of the intermediate product, or a process for preparing a prepreg, comprising the step of bonding matrix resin [B] formed as a film, a knitted fabric made from thermoplastic resin fibers [C] and long reinforcing fibers [A]. The prepregs of the present invention, therefore, are tacky and drapable, and the composite materials obtained by heating and forming the prepregs are high in heat resistance, and very high in impact resistance and inter-layer toughness. Furthermore, the prepregs are easy to produce and high in their latitude in availability of materials, this being industrially significant.

    摘要： The present invention relates to a carbon fiber prepreg. The carbon fiber prepreg of the present invention is characterized in that a carbon fiber bundle comprising a plurality of continuous carbon filaments and having a hook drop value of 10 cm or more as the degree of fiber entanglement is impregnated with a base resin mainly composed of a thermosetting resin, and that particles of 150 .mu.m or less in particle size made of a thermoplastic resin account for 20 wt % or less based on the weight of the entire prepreg and distributed at a higher concentration in the surface zone than in the inside. The carbon fiber prepreg of the present invention is good in tackiness and less changing in tackiness with the lapse of time, and can form a composite with an excellent compression interlaminar shear strength (CILS) at high temperature after moisture absorption while maintaining good impact resistance. It also allows the production of a composite very higher than the conventional composite in the compressive strength (LCS) of a cross laminated panel. The carbon fiber prepreg of the present invention can be preferably used as a structural member in such areas as aerospace area, sporting area and civil engineering and architecture area.
