Abstract
The present invention relates to a short carbon fiber-reinforced composite material, including a base material part and at least one sliding part contacting the base material part, in which each of the base material part and the sliding part has a plurality of short carbon fiber bundles in which at least a part thereof has been converted into SiC and a SiC matrix present among the plurality of short carbon fiber bundles, as constituent components, and the short carbon fiber bundles of the sliding part have a SiC conversion higher than that of the short carbon fiber bundles of the base material part.
