|Title:||Free vibration and dynamic mechanical properties of basalt fiber reinforced polymer composites|
|Abstract:||In this study, the free vibration and dynamic mechanical properties of the surface modified basalt fiber reinforced polymer composites have been investigated. The surface modification of fiber has been carried out with 1N solution. Untreated, acid treated and base treated basalt fiber composites were prepared using Hand layup technique. Fourier transform infrared spectroscopes (FTIR) were used for the study of the effect of surface treatment on fibers. The natural frequencies and damping coefficient of the laminated composites have been analyzed using an impact hammer. The result showed better natural frequencies in the untreated basalt fiber composites than composites prepared with treated fiber. Dynamic mechanical analysis (DMA) was also carried out to find the mechanical properties of the composites as a function of temperature, in this analysis also, Untreated basalt fiber composite were found to possesses good storage modulus, loss modulus and damping factor.|
