Experimental Investigation of Mechanical Performance of Basalt/Epoxy/MWCNT/SiC Reinforced Hybrid Fiber Metal Laminates

Abstract

The primary goal of this study is to see how multi-walled carbon nano tubes (MWCNTs) and nano silicon carbide particles (SiC) affect basalt reinforced epoxy composites made using pressure mould. The aluminium 8090 metal plate was used to strengthen the laminate’s core. Tensile, bending, and low velocity impact tests, as well as aesthetics, were investigated and presented for the debate. The physical and low velocity impact characteristics of the produced laminates are considerably improved by including MWCNT/SiC into the epoxy matrix and basalt mixture. The 9 wt. % and 12 wt. % of SiC filled combinations show higher tensile and flexural performances up to 40% than neat composites among the investigated combinations. Drop weight impact tests show a progressive improved energy absorbing response of up to 60% as SiC reinforcement increases. SEM morphology of pure, SiC/MWCNT filled specimens, as well as fragmented surface analyses, were also presented. It was observed from morphological studies that there is a reasonable wettability between matrix/filler/ reinforcements. This research work will lay a path for using Basalt/Epoxy/MWCNT/SiC Reinforced Hybrid Fiber Metal Laminates for aerospace and structural applications.
