Experimental and Theoretical Study of Mechanical Properties of Matrix Composite Materials

Abstract

In this work, an experimental and theoretical study of the mechanical characteristics of the matrix composite of the Al-Mg-Cu system is carried out. A prediction is given for the elastic moduli and ultimate strength of the composite at a temperature of 20–350 C, taking into account the different volumes of reinforcing fibers, threshold defects, and fiber orientation. The results obtained made it possible to more reliably predict the properties of composites based on aluminum alloys, reinforced with aluminum oxide fibers.
