Micromechanics of Interfaces in Metal Matrix Composites

Abstract

Defining the role of the interface is critical to understanding mechanical properties of metal matrix composite materials. Measurements of interfacial fracture toughness are being conducted to aid in the development of MMC's. The scientific research goals are to develop a better understanding of how nonlinear behavior in the metal matrix and chemical bonding or frictional effects at the bi-material interface combine to provide the interfacial fracture toughness. To accomplish that a number of spectroscopies including RBS and several fracture mechanics approaches including fiber push-out are being employed. These will provide feedback to current processing conditions utilized in MMC's. The practical application is to assist 3M in the Model Factory program.
