Structural evaluation of a composite centrifugal rotor

Abstract

The steady increase in the use of composites has brought benefits in many areas. Polymer Matrix Composite (PMC) is a material consisting polymer (resin) matrix combined with a fibrous reinforcing dispersed phase. Polymer Matrix Composites are very popular due to their low cost and simple fabrication methods. This paper aims to validate thru finite element method the structural integrity of a composite gas turbine rotor and establish its benefits and disadvantages compared to a steel alternative. Composites provide the advantages of lower weight, greater strength and higher stiffness and the advantage of prepreg technology.
