Abstract
The change in static and dynamic characteristics of polypropylene (PP) of grade H110MA by adding 2% multi walled carbon nanotubes (MWCNT) was investigated experimentally in this paper. The nanocomposite material is prepared by mixing neat PP and MWCNT in an extruder in a specified proportion. The extruded material is then used in an injection molding machine to make tensile test and impact test specimen. Tensile test specimen is tested on universal testing machine (UTM) to check the Young’s modulus of nanocomposite material. The impact test specimen is used to find the dynamic characteristics of this material by using the technique of experimental modal analysis using Single point Laser Doppler Vibrometer (SLDV), modal hammer and FFT analyzer. The scanning electron microscopic (SEM) images were taken to check the orientation and dispersion of carbon nanotubes in polypropylene.
