Dynamic Stability of Al-Glass/ Ceramic Composites

Abstract

The effects of compaction pressure and particle size on the mechanical
properties of Al-Glass/ ceramic-based samples are reported in this study. The samples were
of a cross-sectional area of 34.0 x 35.0 mm^2 with varying thicknesses of 20.8-22.10 mm.
The particle size of 26.5 nm was used for glass, ceramic and aluminum powders. The
samples were made into solids by pressing the materials together at a pressure of 30 MPa.
Results showed that ceramic/glass addition and particle size greatly influenced the
mechanical stability of the samples. Regarding the particle size, it was revealed that the
samples were dynamically stable between 0-20 and 40-60 % weights of glass in the
composites. The findings showed maximum strength for 40 % weight of glass or 30 %
weight of ceramic in composites in the compression test analysis.
