Abstract

One of the irritating problems in the study of carbon fiber surfaces is the imaging of sizing. Since the latter is often an epoxy resin, it cannot be differentiated from the embedding resin used for preparing thin sections or composites. Frequently, variations of contrast in the vicinity of the fiber are mistaken for the sizing. Staining is thus necessary. Among the various techniques used, ruthenium tetroxide staining [ 1,2,3,4] was tried on sized PAN based carbon fibers, since staining is successful in the case of many polymers such as polyimides or epoxy. On the contrary, no fixation was observed on polyacrylonitrile.
