Abstract The secondary reinforcement, carbon whiskers, may grow on the surface ofparent reinforcement, carbon fibres, by chemical vapour growth from acetylene using Fe saltsolution as catalyzer. The optimal growing temperature is about 1000℃, and while the con-centration of catalytic solution is appropriate, the carbon whiskers may deposite uniformlyand link each other on the parent carbon fibre surface. If the temperature or concentration istoo high, the coarse cluster of carbon may deposite on the fibre surface. The mechanism ofcarbon whisker growth is believed that the carbon atoms in vapour phase dissolve first in theFe salt drops over fibres, then the solid carbon grains precipitate on the film surface.
