Properties of CF/PA6 Laminate Composites Prepared Using the Carbon Fiber Spreading Technology

This paper reports the preparation of CF/PA6 (Polyamide 6) laminate composites using tow-spreading technology. Additionally, the effect of the spread tow on impregnation 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 stabilize and impregnate the spread tow by covering it with a partially consolidated prepreg: 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 conventional tow prepreg of 12K carbon fiber/PA6 film. Consequently, the spread tow laminate composite exhibited a lower void content and improved mechanical properties.
