Characterization of an In-house Prepared MR Fluid and Vibrational Behaviour of Composite Sandwich Beam with MR Fluid Core

In this research work, two different compositions of MR fluid samples with 24 and 30 percentage (%) volume fraction carbonyl iron (CI) particles are prepared. Prepared (MRF) contain as a dispersive medium, silicone oil carrier fluid, white lithium grease an anti-settling agent. Influence oscillating driving frequency, strain amplitude, magnetic field, the CI particle on rheological properties presented. Storage modulus loss factor equations estimated from rheometry results using linear regression method. The taken to design model sandwich beams ANSYS ACP software, where carbon epoxy composite material is used face layer core material. Modal, harmonic, transient analysis studies have been conducted all modelled beams. thickness, in prepared sample, field vibrational response Carbon-epoxy composites in-house made MRF beam has shown some significant response.
