ハイブリッド射出成形により作製された熱可塑性CFRPの接合強度特性評価

抄録

This study aims to develop the hybrid injection molding method combined with hot pressing for mass production of continuous carbon fiber reinforced thermoplastic parts. A new type of heating system for hybrid injection molding was originally developed using near-infrared light and its linear drive carrier. The results shown the fusion bonding between woven CF/PA66 laminate formed thermally and short CF/PA66 injection-molded was significantly affected by the injection pressure and the heating time of woven CF/PA66 laminate, while the surface of skin layer was also thermally-deteriorated by overheating. Thus the heating conditions should be optimized to be satisfied the both fusion bonding strength and the surface quality.
