Reinforced phenol resin (PF) was prepared by in situ polymerization of different fractions of nano polytetrafluoroethylene particles (nano-PTFE) undergone grafting acrylic acid irradiation. The bending strength and hardness of the material, according to mechanical property testing, were improved by the grafted nano-PTFE. The tribological properties of PF composites were investigated by a block-on-ring...
