Evaluation of three-component boron-free glass fiber/TiO₂/polyimide nanocomposite properties prepared by 3D turbula dispersion and spark plasma sintering method

Interest has grown in recent time on the development of three-component polymer nanocomposite with enhanced properties. However, study focuses effect TiO 2 nanofiller mechanical, tribological, dielectric, and corrosion resistance properties boron-free glass fiber (BGF) reinforced polyimide (PI) composite produced spark plasma sintering route. Microstructure samples was examined using scanning electron microscopy. Mechanical, thermal, behaviour were characterized by nanoindenter, ball-on-disc, LCR meter, TGA, potentiodynamic polarization test, respectively. The SEM results show that introduction nanoparticles into BGF/PI aids more uniform distribution BGF particles within PI matrix, thus good interfacial interaction matrix structure. Comparing sample BGF/TiO /PI nanocomposite, it observed depicted better hardness, elastic modulus, low friction coefficient wear rate, With additions, hardness modulus improved 56.6% 10.1%, In addition, composites filled a 0.07 rate about 67.7% reduction than neat 9.0% pristine composites. Improved interactions between reinforcements host are suggested as possible mechanism resulting to desirable recorded. Finally, developed is be favourable for automobile, aerospace, microelectronic device applications.
