Аннотация: The method of synthesis of CNF/MF carbon-carbon composites by growing carbon nanofibers (CNFs) on a surface of carbon macrofibres (CMFs) is described. The method is based on catalytic gas-phase deposition of carbon (using C1, C2 hydrocarbons and the mix of C2-C4). Depending on the conditions of modification (composition of catalytiПоказать полностьюc particles, type of hydrocarbon, and temperature), it is possible to obtain CNFs with different morphologies (feathery, fishbone, or platelet fibers). It is found that the modification of MFs by CNFs (0.2–0.3 g/gMF) allows increasing the specific surface area of the initial material in an order of magnitude (up to 25 m2/g). The method is proven to be applicable for the modification of various materials made of CMFs (chopped fibers, tows, and carbon fabric). © 2015, Pleiades Publishing, Ltd.
