Investigation of the Effect of Filling Ratio on Mechanical Properties of Pumice Filled Epoxy-Based Composites.

Abstract

This study attempted to fill epoxy, a widely used industrial material, with pumice, a cheap volcanic rock, in order to form a composite material. The objective was to evaluate the worth of the pumice and improve the mechanical properties of the epoxy. Composite samples with no filler, 10%, 20%, or 30% filler were produced. An ultrasonic mixer during manufacture made sure the powder was dispersed properly, and vacuuming stopped air pockets from accumulating in the composite. The mechanical characteristics of the composites were evaluated by compression testing, and the post-production distribution of the powder was observed using optical microscope pictures. Finally, XRF analysis was used to establish the composition of the pumice powder. The outcomes demonstrated that adding filler greatly enhanced the maximum stress and unit strain values of the composites.
