Characteristic Study on Sisal Fibre Hybrid Composites Filled With Nano SiO₂ and Marble Dust Particles

Abstract

The synthetic fibres are having high stiffness and strength still high manufacturing cost with environmental issues limited the use of synthetic fibres. This encourages towards thinking of intense research of natural fibres having similar property as synthetic fibres. To obtain the better mechanical and thermal property, hybridization of fibres is mostly preferred and that leads to minimize the use of synthetic fibres. As natural fibres are strong and having more ductile property, though moisture absorption is the primary limitation. So fibres is subjected to various treatments such as physical, thermal, chemical and laser treatments etc., to improve the surface characteristics with better interfacial bonding. Nano particle addition also helps in improving the performance of composites and develops cross linking in bonding of matrix and fibre. This research work mostly focuses on hybridization of short mercerized sisal and glass fibre filled with nano silica and marble dust particles, by injection moulding process with polypropylene matrix. It is noticed that among the addition of different fillers, marble dust added composite gave the better result than SiO2 added composite. Incorporation of SiO2 particles as filler material improves the flexural strength and thermal property of the composite.

Epoxy‐hemp and epoxy‐flax composites filled with glass dust for enhanced thermal insulation: An analytical and experimental study

“…as industrial waste fillers. [22][23][24] With the addition of such industrial waste as fillers, the mechanical and thermal properties of the natural fiber reinforced polymer composites have been found to be changed. The review of industrial waste filled fiber composites suggests that there is hardly any report showing the use of waste glass dust generated in glass cutting industries as filler in polymers.…”

“…Most of the investigators used fly ash, marble dust, silica fumes, red mud, bagasse ash, etc. as industrial waste fillers 22–24 . With the addition of such industrial waste as fillers, the mechanical and thermal properties of the natural fiber reinforced polymer composites have been found to be changed.…”
