Abstract: Provided are: a fiber structure including two types of heat-crosslinkable thermoplastic resins; and a crosslinked molded body obtained by heat-crosslinking the thermoplastic resins with each other. The fiber structure includes at least a thermoplastic resin A and a thermoplastic resin B both heat-crosslinkable with each other. The thermoplastic resin A is an amorphous epoxy-type resin, and at least one of the thermoplastic resins A and B has a fiber shape.

Abstract: Provided is an amorphous epoxy fiber excellent in dimensional stability, a fiber structure comprising at least in part amorphous epoxy fibers, and a molded body formed by melting said fibers. The amorphous epoxy fiber has a birefringence value of 0.005 or lower. For example, the amorphous epoxy fiber may include an amorphous epoxy resin represented by the following general formula: in which, X is a residue of a bivalent phenol and n is 20 or greater (preferably 20 to 300, more preferably 40 to 280, still more preferably 50 to 250). The amorphous epoxy fiber may have an average fiber diameter of single fibers of 40 μm or smaller.
