Experimental and Numerical Studies on Radial Tensile Strength of Composite Rotor
Abstract: This paper describes the experimental and numerical studies on the radial tensile strength (RTS) of composite rotor. Carbon/epoxy composite rotors were fabricated using a filament winding process and their radial tensile strength was determined by diametric tensile testing of composite C-rings. The radial tensile strength of the composite rotor was measured as ~ 22 MPa and the failure was found to occur circumferentially symmetric about the horizontal plane of the …
