Carbon fiber and process for preparing same
 Carbon fiber superior in processability and in physical properties as a composite is obtained by treating carbon fiber with an epoxy resin composition incorporating a polyalkylene ether glycol derivative represented by the following general formula (I) or (II): ##STR1## wherein R.sub.1 is alkylene of C.sub.1 to C.sub.30, R.sub.2 is alkyl of C.sub.1 to C.sub.30, R.sub.3 and R.sub.4 are each hydrogen or methyl, R.sub.5 is glycidyl, X is ether linkage (--O--) or ester linkage ##STR2## m and n are integers of 1 to 20.
