Chopped carbon fiber-reinforced epoxy composites were fabricated and tested for tribological behaviour. Wear behaviour of composites was studied using pin-on-disc wear tester device. The design of experiment, using Taguchi method, was employed to analyse the results. Signal to noise ratio and analysis of variance (ANOVA) were used to determine the influence of parameters on the wear rate and coefficient of friction.

Chopped bamboo-reinforced epoxy composites were fabricated and tested to investigate their tribological properties. Three different weight fractions of 6%, 8% and 10% were used as reinforcement in the composites. Wear behaviour of composites was investigated by pin on disc wear testing device. To analyse the results the design of experiments (DOE) approach by using the Taguchi method was employed. Three different parameters (load, sliding speed, weight fractions) with three levels were chosen in design of experiments. Signal to noise ratio and analysis of variance (ANOVA) were used to investigate the influence of parameters on the wear rate and the coefficient of friction. According to the results, load was the most effective parameter for both wear rate and coefficient of friction.

Chopped E-glass fiber-reinforced epoxy composites (10%, 30% and 50%) were fabricated and their mechanical and tribological behaviour was investigated. Three-point bending tests were performed according to the ASTMD790 and tensile tests were performed according to the ASTMD638 standards. Impact tests and hardness measurements of the composites were also carried out. Wear behaviour of composites was studied using pin on disc wear testing device. The design of experiments approach, using Taguchi method, was employed to analyze the results. Signal-to-noise ratio and analysis of variance were used to determine the influence of parameters on the wear rate and coefficient of friction.

A beam profile monitoring system based on the imaging of low energy electrons created when the ion beam impinges on a metal plate was built to monitor the beam profile and to cover the wide range of beam intensities and energies for the DESIREE (Double ElectroStatic Ion Ring ExpEriment) beam line diagnostics. The spatial resolution of the system was tested with different beams of various energies and was found to be around 2 mm. A significant steering effect on the ion beam before hitting the metallic foil was observed at low energies.

E-glass fiber reinforced epoxy composites were fabricated by hand lay up method and tested for investigating tribological behaviours. Wear behaviours of composites 0°, 90° and [0°/90°] oriented were investigated by pin on disc wear tester device for a constant distance (1000 m) and the design of experiments approach using the Taguchi method was employed. The tests were conducted sliding against a steel disc (60 HRC) under different sliding and loading conditions. Signal to noise ratio and analysis of variance (ANOVA) were used to investigate the influence of parameters on the wear rate and coefficient of friction.
