“…12 -16 Other researchers were interested in the effect of different reinforcements (glass fiber, aramid fiber, carbon fiber, graphite and wax, titanium carbide particles, aluminum borate whiskers, and polypropylene) on the tribological properties of another matrix, such as PA6, PA12, poly(ether ether ketone), polyimide, and polyethyleneimine. 17 -23 Addition of reinforcements will affect mechanical but especially tribological properties of PA 66 and the effect needs to be clearly understood for better utilization and widening application of this PA-based polymer composites. An extensive study of tensile, flexural, friction, and wear behaviors of different glass fiber-reinforced PA 66 is conducted.…”

Tensile, flexural, wear, and friction behaviors of polyamide 6.6 (PA 66) reinforced by different weight fractions of short glass- iber were investigated. Three-point bending flexural tests in addition to monotonic tensile tests were carried out to determine the mechanical behavior. Reciprocating friction tests were carried out without lubrication under ambient conditions. A ball-on-flat contact configuration was adopted for all tests. Reciprocating wear tests were carried out against a silicon carbide abrasive paper. Results show that the reinforcement influenced mechanical and tribological behaviors and that the orientation of glass fiber has an effect on the friction behavior. Increasing the weight fraction of glass fiber increases the ultimate strength, the flexural strength, and the elastic modulus but decreases the elongation at break. Increasing the weight fraction of glass fiber decreases the coefficient of friction and increases the wear rate. For high weight fractions, when sliding parallel to the glass fiber direction, the coefficient of friction is smaller than which is measured in the perpendicular direction. Abrasive wear mechanism of wear was illustrated via scanning electron micrographs.

“…Typical factors include insufficient material strength, improperly determined thickness, circumferential impeller unbalance, and cavitation. 10 The operation of the pump with a damaged impeller emits signals like noise and vibration. Furthermore, the aggravation of the damage might incur serious results.…”

Emphasis is placed on the performance of a two-stage pump equipped with an eroded impeller. Non-contact reverse engineering technique is utilized to acquire the point data constituting the three-dimensional geometrical model of the eroded impeller. With computational fluid dynamics, both the operation performance of the pump and flow patterns adjacent to the eroded blade surface are obtained. For comparison, the corresponding undamaged impeller is investigated as well. Preferable fidelity of the approach of constructing geometrical model of the damaged impeller is substantiated. The mechanism underlying performance degradation of the pump with the eroded impeller is evidenced. Local flow patterns near the eroded area are featured by explicit irregularity. Furthermore, between the defective and the undamaged pumps, disparity in positions where cavitation occurs is negligible.
