Mechanical and Tribological Properties of Phenol Formaldehyde Resin Reinforced with Nano-Silica



Reinforced phenol formaldehyde resin (PF) matrix nanocomposites with different nano-SiO2 were fabricated with two-roll compounding and compression molding technology. The mechanical and tribological behaviors of the reinforced composites were studied. The friction and wear experiments were tested on a constant speed machine (D-SM). The impact and flexural strength of nanocomposites were increased by the addition of various types of SiO2, but the flexural modulus was decreased. The effects of the addition of various types of SiO2 on tribological properties of the composites were explored in this study. The results showed that the coefficient of friction of the composites increased, while the wear rate values decreased at various temperatures. Microstructure of worn surface of the tested composites was observed by scanning electronic microscope (SEM) and the wear mechanism of the reinforced composites was studied.
