Abstract:

In this study, scratched glass fibres with different fiber size/diameter ratio have been transformed into a fiber opened with pressure air and used in the supplementation of the epoxy matrix. Tracking resistance, inclination resistance and heat conductivity tests were performed for composites produced by hand-setting method with a weight of 5% and 10% and 15% of the fiber supplement. The result is compared with the crushed glass fiber supplementary compounds produced in parallel processing parameters. The lift opening time has not been shown to be dependent on the length/diameter of the cuted fiber used and the fiber length has a more significant effect on the fiber opening time than the fiber diameter. It has been observed that crushed glass fiber with a long fiber length responds faster to the fiber opening process. The lift opening process has generally caused a decrease in the drawing and inclination resistance of the composites but increased in the isolation properties. For the type of glass fiber with a lif size/diameter ratio of 4.5 mm/13 μ, the use of opened fiber is a matter of achieving a higher drawing resistance in lower concentrations. The effect of the fiber length on the turning resistance is high and after the opening process, the fiber length/diameter ratio of 3 mm/13 μ and 4.5 mm/10.5 μ glass fiber types have become more consistent in the turning resistance behavior. The lift opening process has been shown to be effective in the decrease of the heat transmission rates of the compounds and makes the compounds more isolated.
