X-ray diffraction and thermo gravimetric analysis of surface modified areca sheath fibre epoxy composites

Chandrappa Ravi Kumar, Kamath Sakshi Shantharam

Journal of Mechanical and Energy Engineering

2022

Vol. 6, No 2

1--6

Focus of the current study is to shed more light on thermal behaviour of composites made up of areca sheath fibres. The XRD analysis revealed that crystallinity index and crystallinity percentage increased with different treatments, as it leads to better interaction of fibre and resin. The crystallinity percentage of alkali treated fibre and benzoyl peroxide treated fibre increased by 5.87 and 8.44% respectively compared to untreated fibre. This was further evident in thermal studies which proved better thermal stability in benzoyl peroxide treated fibre composite.

Egg shell as a filler in composite materials - a review

Kamath Sakshi Shantharam, Chandrappa Ravi Kumar

Journal of Mechanical and Energy Engineering

2020

Vol. 4, No 4

335--339

Current focus is on polymer and metal matrix composites for their increased mechanical properties. The strength of the composites is further enhanced by incorporating different types of additives which includes fillers, flame retardants, silanes, coupling agents and so on. One such additives is egg shell powder which influences the strength of composites and thus, gains the attention of researchers for its incorporation in composite fabrication. The work is in progress with respect to utilizing waste egg shell in composite fabrication, which not only finds solution for the waste disposal, but also enhances the strength of composites manufactured. This work is the compilation of work done by different researchers with egg shell in composites, so that the need of its utilization in the manufacture of composites will be stronger.
