Abstract:
1. A carbon fiber composite material, comprising: a thermoplastic resin; carbon nanofibers dispersed in the thermoplastic resin; and dispersing particles which promote dispersion of the carbon nanofibers in the thermoplastic resin: wherein: the carbon fiber composite material has a first-component spin-spin relaxation time (T the carbon fiber composite lacks or has a second-component spin-spin relaxation time (T the fraction of components having the second-component spin-spin relaxation time is less than 0.2, as measured at 250° C. by Hahn-echo method using a pulsed NMR technique with if the carbon fiber composite has a second-component spin-spin relaxation time (T
