Dynamic Stability of Al-Glass/ Ceramic Composites

Abstract

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 mm2 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.
