Abstract
In this study, it was studied that the abrasion resistance and characteristics of polymer composites with fly ash (FA). The epoxy based polymer composites are produced with resin and FA as mineral additive. Mixtures of different ratio by replacing the FA were added to the resin from 0 to 30% by weight. Polymeric samples were cured in air conditioning and they were taken from the molds after 24 hours. Polymeric samples gain ultimate strength after 7 days. Therefore, abrasion tests were performed on 7 aged specimens. Abrasion characteristics of polymer composites were defined by pin-on-disc test for 500 m under a dry friction condition and room temperature. Three types of loading conditions were carried out as 5, 10, 15 and 30 N. The hardness and wear resistance values increased with the increase in the content of fly ash. Showing the relationship between wear rate and hardness, an equation with parameters dependent on load was provided. There was an increase in the friction coefficient with an increase in the surface roughness values. In addition, dynamic friction was as a function of the wear rate. The wear surfaces of the polymer composites were analyzed using scanning electron microscopy. It was observed that the wear rate of the polymer composites and pure epoxy samples ranged from 17.82 to 172.96 mm3/Nm.
Highlights
Fly ash produced during coal burning for energy production is an industrial side considered as an environmental contaminant [1]
This case showed that there is a good bond between fly ash grains and polymer matrix
The hardness values of 10% fly ash (FA), 20% FA and 30% FA blended polymer composite samples were obtained as 86 HD, 88 HD and 91 HD, respectively
Summary
Fly ash produced during coal burning for energy production is an industrial side considered as an environmental contaminant [1]. It is generated in million tons worldwide due to heavy industrial growth and a very few percentage is reused in different purposes. This large amount of industrial waste can cause significant environmental and ecological problems if not properly handled. The main use of fly ash is in making of Portland cement, road embankment and fly ash bricks Beyond these large scale applications, fly ash hasn‟t been used in product development and automobile industries which may play an important role in its reuse. Epoxy resin is a cheap semi viscous fluid which becomes a strong matrix material when a ceramic filler like fly ash is used in it. Very few attempts have been made to use the cheap materials like rise husk, coir, jute fibre and even chicken feather [4, 5]
