ている。In recent years, carbon fibers (because they have a high specific strength and specific modulus with a carbon content of 95% by weight or more) have been used in the form of long fibers or short fibers in composites with various matrix materials. In particular, resorcinol fiber bundles are used as reinforcing materials for rubber and plastics, and their applications are expanding to industrial materials such as tires and belts, sporting goods, and the aerospace field.
一般に、これら被覆材は炭素繊維の束としての取り扱い
易さを改善するだけでなく、炭素繊維相互を十分に接着

amの特性を充分発揮し得ないという欠点を示す。As a coating method, for example, the fiber bundle is immersed in an aqueous or organic dispersion of the coating material, or the fiber bundle is sprayed with the dispersion or solution. However, especially when coating carbon fiber bundles in the form of an aqueous dispersion, the thickness of carbon fibers is usually extremely thin, 15 microns or less, whereas the particle size of the coating material is 5 to 5 microns. Although it is possible to attach it to the outside of the fiber bundle, it is possible to impregnate the inside of the fiber to form a monomM
It has tended to be difficult to coat the When a carbon fiber bundle having a coating material thus obtained is handled, the uncoated single fibers inside the fiber bundle are likely to be exposed, and the fuzz of the fiber bundle tends to increase. In addition, when composited with a matrix, the adhesion becomes low because the monomers inside the fiber bundle are not covered.
This shows the drawback that the characteristics of am cannot be fully exhibited.
