Abstract

It’s a known fact that many control parts of an automobile go through relentless pulsation / vibration during its motion, to counteract this behavior of the control parts it is recommended to select composite materials in the manufacturing process over other available types of materials because of its various advantages. In this scenario, natural fibres viz. sisal, basalt etc., could be utilized in manufacturing certain control parts of an automobile as these are biodegradable, economical and light in weight. In this study, an attempt is made to prepare the composite plates and investigate the free vibration characteristics of woven basalt fibre vinyl ester reinforced composite plates where basalt fibre is considered as a reinforcement and vinyl ester as a matrix (BFRP). These composites plates were prepared by compression moulding technique with different basalt fibre to vinyl ester resin ratios of 60:40, 50:50 and 45:55. The natural frequencies and mode shapes for these prepared laminates were determined
