DEVELOPING AND CHARACTERIZING NEW MULTIPHASE COMPOSITE MATERIALS FOR AUTOMOTIVE BRAKE ROTORS

Abstract

The paper focuses on development and material properties measurements of new structural combinations of particle-particle multiphase polymeric composite materials. The composites were manufactured using a self-developed technology, embedding in different volume fraction iron oxide and black carbon into a polymeric matrix with the purpose of obtaining a new material with improved mechanical and thermal properties to be used for automotive brake rotors. The paper focuses on one of the most important thermal property, the linear coefficient of thermal expansion (CTE), which represents the structures’ stability related indicator. This thermal property will be measured using a differential dilatometer DIL 402 PC from Netzsch (Germany). Based on the experimental data retrieved, several manufacturing and structural composition related influencing factors will be identified with the purpose of tailoring further material combinations for automotive brake rotors.
