In injection molding of carbon fiber reinforced thermoplastic matrix composites (CFRTP), to detect ununiformity in fiber dispersion and deviation in fiber orientation are necessary in actual use, because they affect seriously on the strength of molded parts. In this study, to develop prompt detection method thermal response on the surface when the injection molded parts were directly heated by induction heating was examined whether it reflected the inner fibers state. Temperature rise measured resulted that it varied depending on fiber length and presence of weld.
