COMPOSITE RAW MATERIAL, PREPREG, CARBON FIBER REINFORCED MOLDED BODY, AND MANUFACTURING METHOD OF COMPOSITE RAW MATERIAL

摘要

To provide a composite raw material capable of sufficiently exhibiting effects of a carbon nanotube, a prepreg using the same, a carbon fiber reinforced molded body having larger progress resistance of delamination cracking, and a manufacturing method of the composite raw material.SOLUTION: A composite raw material has a carbon fiber bundle in which a plurality of continuous carbon fibers 12a is arranged, a carbon nanotube 14a adhered to each surface of the carbon fibers 12a, and a plurality of fixing resin parts 16a for fixing the carbon nanotube 14a to surfaces of the carbon fibers 12a partially, in which the plurality of fixing resin parts 16a covers 7% to 30% of surfaces of the carbon fibers 12a to which the carbon nanotube 14a is adhered.SELECTED DRAWING: Figure 3
