Dynamic and vibrational characterization of natural fabrics incorporated hybrid composites using industrial waste silica fumes

Abstract

Recycling of industrial waste into a useful component is very necessary than dumping into the nature. Silica fumes, a byproduct of producing silicon metal or ferrosilicon alloys, are used in this study as filler material in the composite. This study deals with the dynamic and vibration properties of the natural fabric reinforced polymer hybrid composites containing silica fumes. The composites are prepared by hand lay-up process using jute, linen and epoxy matrix. To increase the dynamic and vibration properties of the composite, industrial waste i.e. silica fumes is added as filler material (in 1, 2, and 3 wt%) to the composites. The dynamic and vibration properties are acquired using dynamic mechanical analysis and vibration analysis, respectively. The glass transition temperature is also determined. Upon adding a small quantity of silica fumes, the composites’ storage modulus, loss modulus, natural frequency, and glass transition temperature have increased significantly. However, owing to agglomeration of silica fumes, the composite’s above-mentioned properties have not increased for silica fumes adding beyond 2% weight fraction.
