Influence of Barium Titanate Nanopowder on the Thermo-Mechanical, Damping and Vibration Characteristics of Epoxy Laminates
Source abstract
Abstract
This article presents the experimental study of thermomechancial, free vibration, and damping characteristics by reinforcing barium titanate nanopowder (0, 1, 3 and 5 wt%) in the epoxy matrix using the resin casting method. Theoretical study is also carried out to study the vibration characteristics of barium titanate/epoxy nanocomposites. Dynamic mechanical analysis shows an increase in the storage modulus and glass transition temperature with a maximum value of 6400 MPa and 154°C for 3 wt% barium titanate nanopowder in epoxy polymer matrix. Dynamic results show that the second phase barium titanate nanopowder dispersion in the epoxy matrix enhances the internal damping of laminates up to 3 wt%.
