近赤外線加熱を用いた熱可塑性CFRPプリプレグテープの自動積層成形

抄録

This study aimed to predict the optimum processing condition for thermoplastic tape laying such as flat laminates and pipe molding. The material used for the experiment was unidirectional carbon fiber reinforced polyamide 6 prepreg tape. The effects of processing conditions such as lamination number, tension of prepreg tape, feed speed of prepreg tape and pressure of compaction roller on the laying behavior of prepreg tape were investigated. The thickness of the molding parts was measured by micrometer. The cross-section images was obtained by microscopic observation. It was revealed that the tension of prepreg tape affected the quality of the molding part remarkably.
