Epoxy Resin Composite

Abstract Noise is an unwanted sound; requires reduction and control through the use of absorptive materials. This is imperative due to the adverse effect noise poses to human health, knowledge dissemination, and tranquility which is increasing daily due to industrialization and heightened allied activities. The use of natural and synthetic reinforced composites in noise pollution control is an emerging area of research. This study aims to develop and characterize fly ash nanoparticles reinforced epoxy resin composite for acoustic applications. Samples were prepared with fly ash nanoparticles reinforcement at 5%, 10%, 15%, 20%, and 25% and investigation of noise reduction coefficient (NRC), porosity and mechanical properties (hardness, impact, flexural strength) of samples were done. Cenospheres were obtained when fly ash particles were characterized separately with the aid of sieve analysis and x-ray fluorescence analysis. The cenospheres are hollow spherical and lightweight, inertfiller material. Correlation between porosity of the samples and their sound absorption properties was observed and showed that as porosity increased, the NRC values increased and as the porosity decreased the NRC values decreased. It was also observed that heat of polymerization, fly ash nanoparticles structure and air bubbles during sample preparation (mixing) influenced the porosity values which in turn influenced the NRC values of the composite. There was also a steady decrease in mechanical properties, as reinforcements were added (5%, 10%, 15%, 20%, and 25%), this was attributed to the high surface areas and shape of reinforcement added.

Composite Properties

This article researched fly ash-epoxy resin composite properties and microstructure changing with the increase of epoxy resin content. The result show that, when the epoxy resin content increased to 30%, the tensile strength, rupture elongation and impact strength of composite increased to 329%, 168% and 257% respectively compare with the composite of epoxy resin content is 15%, and various properties change little with the epoxy resin content continuous increasing. And the composite formed 2μm or so and uniform distributed micro-pores when the epoxy resin content is 30% and the consistency of micro-pores increasing and some small micro-pores gathered into larger with the epoxy resin content increasing. Considering various properties, the fly ash-epoxy resin composite has the highest cost-effective when the epoxy resin content is 30 ~ 40%.
