description Disclosed is a layered carbon-fiber product obtained by layering one or more sheets of carbon-fiber fabrics each prepared using one or more carbon-fiber bundles each comprising a plurality of carbon fibers arranged in a single direction. The layered carbon-fiber product is characterized in that at least a part of said surfaces and/or edge faces of said layered carbon-fiber product is constituted of a graphitized part and that said graphitized part exhibits a Raman spectrum in which said intensity ratio of said D band to said G band (D-band intensity/G-band intensity) is 0.3 or less. Also provided are a preform prepared using the layered carbon-fiber product and processes for producing the layered carbon-fiber product and the preform. The edge faces of the layered carbon-fiber product or preform can be easily processed, and it is possible to highly accurately trim the layered carbon-fiber product or preform while preventing the carbon fibers from fraying at the edge faces. Consequently, the layered carbon-fiber product and the preform can be easily and accurately disposed in a die and deburring can be omitted, making it possible to attain a cost reduction and a reduction in production time.
