Abstract
Reinforcement of glass fibers at the weld joint interface of polyamide 66 (PA66) was investigated aiming to improve the weld strength but rather found to improve the tribological properties. The weld strength of glass fiber reinforced polyamide 66 was found to be in the range of 46 %–52 % of that of the parent material. The dry sliding wear behavior of the friction stir welded polyamide 66 with and without glass fiber strengthening was investigated in this experimental study, using a pin-on-disk wear tester. The worn surface topography and morphology were analyzed via white light interferometry and scanning electron microscope, respectively. The wear study confirmed that PA66 reinforced with high fiber content of 20 % by weight of polymer (GF/PA66) yielded a minimum specific wear rate and coefficient of friction.
