Effect of filler-ash on the properties of epoxy resin composite

Abstract

At present in Russia a huge amount of ash and slag waste from thermal power plants is accumulated in dumps and heaps. For several decades the problem of utilisation of non-combustible residues generated during coal combustion has been studied. These wastes are unfavourable for the environment due to toxic substances and heavy metals in their composition. Ash and slag waste is a type of waste generated during combustion of coal with high ash content in the boiler at thermal power plants. The use of ash as a filler in thermal insulation material not only reduces the cost of scarce and expensive materials, but also increases the strength characteristics of the composite material. This paper deals with the method of ash utilisation, use of ash as a filler component in composite material. The aim of the study is to develop the composition of insulation of pipelines and their tensile strength tests. The task is to test prepared specimens of glass fibre, epoxy resin, hardener and ash under tensile strength on a universal testing machine REM-A.
