Process for producing fusion-bonded material

摘要

A fusion-bonded body (100) which includes a fusion-bonded part (101) obtained by fusion-bonding to each other a first part to be fusion-bonded (111) which comprises a first thermoplastic resin (NA1) and first carbon fibers (CF1) and a second part to be fusion-bonded (121) which comprises a second thermoplastic resin (NA2) and second carbon fibers (CF2). Also provided is a method for producing the fusion-bonded body which comprises a fusion-bonding step in which the first part to be fusion-bonded is brought into close contact with the second part to be fusion-bonded, an electric current is caused to flow through the two parts to generate heat and melt the first thermoplastic resin and second thermoplastic resin, and the molten resins are solidified to form a fusion-bonded part.
