A STUDY ON THE COMPOSITE SCREW ROTORS FOR SUPERCHARGERS

Abstract

In this work, the screw rotors for superchargers were manufactured with chopped carbon fiber epoxy composite materials by resin transfer molding process. The manufactured composite screw rotors were tested in different combinations such as the male composite and female composite rotors, the male composite and female aluminium rotors, and the male aluminium and female composite rotors. The temperature and pressure increases of the air at the outlet and the required torque of the supercharger were measured with respect to the angular velocities.
