Automated Tape Laying (ATL) in which Carbon fiber reinforced thermoplastic (CFRTP) prepreg tape is heated to the vicinity of the melting point and lamination molding is performed in an arbitrary direction have attracted attention in aircraft and automobile applications. This study focused on the heating behavior, thermal distribution in a layup process of unidirectional carbon fiber reinforced thermoplastic prepreg tape to predict the optimum processing condition for carbon fiber continuous tape layup molding equipment developed in. The material used for the experiment was unidirectional CF/PA6 prepreg tape. The source of heat was used near infrared heating and high frequency induction roller heating. The effect of processing conditions such as feed speed, plating effect, Shape and temperature of heating part on the layup behavior of prepreg tape were investigated. From the experimental results, Semicircular heating of Teflon-coated hard chromium plating has less adhesion of resin on the surface of the heating part comparison of Roller heating, the formability was also improved. Moreover, it has long heating area of prepreg tape, the forming speed also improved.
