Carbon fibers for composite materials having improved electrical conductivity

摘要

The present invention is made of carbon fiber filaments having a metallization relates carbon fibers having conductivity, the time, the carbon fiber filaments, it contains conductive nanoparticles, based on the binder of at least one polymer set to the a metal coating formulation present on, and relative to the weight of the carbon fibers with the case in each of the metal coatings and preparations, the concentration of the metal coating, with 8-25 wt% The concentration of enabled with the carbon nanotubes is 0.1 to 1 wt%. The present invention further includes a manufacturing method, as well as carbon fibers consisting of carbon fiber filaments of the fiber, and a fiber reinforced composite material, the carbon fiber filaments in that case, assumed to be coated with a metal, and polymer fiber volume proportion of the respect and matrix to a base, the composite material during its is 45~70Vol%, and the composite material further at least partially conductive nanoparticles are dispersed in the matrix me to contain.
