A STUDY ON THE COMPOSITE SCREW ROTORS FOR SUPERCHARGERS

In this work, the screw rotors for superchargers were manufactured wit h chopped carbon fiber epoxy composite materials by resin transfer mol ding process. The manufactured composite screw rotors were tested in d ifferent combinations such as the male composite and female composite rotors, the male composite and female aluminium rotors, and the male a luminium and female composite rotors. The temperature and pressure inc reases of the air at the outlet and the required torque of the superch arger were measured with respect to the angular velocities.
