    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.

    摘要： The present invention provides a prepreg having an excellent self adhesiveness to a honeycomb core, a low porosity when used as skin panels, an excellent surface smoothness due to a low surface porosity, and good tackiness and drapability. This invention also provides a honeycomb sandwich panel having a skin panel peel strength, an excellent impact resistance and an excellent hot water resistance, and a composition for a fiber reinforced composite material made from the prepreg and honeycomb sandwich panel. The fiber reinforced composite material made from the prepreg of the present invention can be used for airplanes, automobiles and other industrial applications, particularly as structural materials of airplanes, because of its excellent mechanical properties.
