Regarding the Tensile-Strength and Impact-Strength of the Injection Moulding of long fiberglass-reinforced thermoplastics, it is very important to keep the fiberglass at its normal length in order to display its characteristics. Data were obtained in my first report from experiments using two ordinary screws. This second report is based on the findings of the first one. For this report, I developed, moulded and tested a new screw. As a result of the experiments, the impact strength increased 15 percent and the length was doubled; on the other hand, the tensile strength did not so increase. I found the new screw was practical.
