Abstract
Continuous graphite fibers were impregnated with thermoplastic resin using a research scale, single tow, drum winding prepreg machine. The method of impregnation was a solution dip, with a wedge-slit die. Several parameters were varied but special atten tion was given to the fiber tow velocity and the fiber tow tension. Prepreg samples were evaluated to determine volatile and resin contents. Photomicrographs were taken to deter mine the degree of impregnation and the fiber/resin distribution.
