Push-Out Method for Micro Measurements of Interfacial Strength in Aluminium Alloy Matrix Composites

Materials (Basel). 2021 Sep 6;14(17):5092. doi: 10.3390/ma14175092.

Abstract

The main goal of this work was the evaluation of the interfacial strength of the carbon fibres/aluminium matrix interface dependently on the utilised composite fabrication method, namely high pressure die casting and gas pressure infiltration. In addition, the influence of a Ni-P coating on the C-fibres was investigated. The proposed measurements of the interfacial strength were carried out by means of the "push-out" method. The interfacial strength of the samples fabricated using the high-pressure infiltration method average between 19.03 MPa and 45.34 MPa.
