Abstract

In order to study the dispersion effect of chopped carbon fibers in fluid medium, an experiment was designed to disperse carbon fibers by explosion in the air while another was by ultrasonic waves in mixed solvent of ethanol and acetone. A characterizing method has been set up based on the number of single chopped carbon fibers. For an example, the dimension, shape and distributing law were measured based on the experimental data of explosive dispersion in the air. By the results, the chopped carbon fibers can be effectively dispersed in fluid medium by some outside force. The main procedure of ultrasonic dispersion for chopped carbon fibers in the mixed solvent of ethanol and acetone is single carbon fiber silks separated from each other along radial direction. The main procedure of explosive dispersion in the air is not only single carbon fiber silks separated from each other along radial direction but a little of single carbon fibers are broken into small pieces along axial direction. The least discrete unit is a single carbon fiber silk while the bigger one is an aggregate which is composed of several single carbon fiber silks.
