Abstract
This paper reports the preparation of CF/PA6 (Polyamide 6) laminate composites using tow-spreading technology. Additionally, the effect of the spread tow on impregna- tion was investigated by Darcy's law. The thickness of an unspread 12K carbon fiber tow was reduced by increasing the tow width from 7 to 20 mm. The PA6 film was used to stabi- lize and impregnate the spread tow by covering it with a partially consolidated pre- preg:12K carbon fiber spread tow/PA6 film. The laminate composites were fabricated from the prepreg and, for comparison, the other laminate composite was produced from a con- ventional tow prepreg of 12K carbon fiber/PA6 film. Consequently, the spread tow lami- nate composite exhibited a lower void content and improved mechanical properties.
