Outline of Final Research Achievements

In this study, the influence of typical injection molding conditions and reinforcement fiber on joining strength was investigated in joining resin and aluminum plate with uneven surface by injection molding. Moreover, visualization of resin flow into the fine uneven part on the metal surface was carried out, and the injection molding conditions for enhancement of joining strength were proposed.　As a result, it was inferred that the cause of enhancement of joining strength is reduced in molding shrinkage by reinforcement fiber. Also for the improvement in joining strength of injection molded parts joined with metal and resin, it was concluded that high filling speed is essential to make growth of the solidification layer delayed.
