Poliamit 6/Mika kompozitlerin mekanik ve tribolojik performansına mika katkı oranının etkisi.

Since electrical insulation, mechanical performance and wear resistance properties are expected from some parts working in the electrical industry, PA6 (PA6-M) composites filled with 10, 20 and 30 wt% mica have been produced to provide the required performances. PA6-M composites were first produced in granule form in a compounding machine designed as twin screw. Afterwards, mechanical and tribological test specimens were molded using injection moulding method. The mechanical and tribological performances of the composite test specimens were investigated. Tensile, notched Izod impact and hardness tests were performed to determine mechanical properties. Tribological tests were carried out in a pin-disc wear test rig under dry conditions and at ambient temperature. Tribological tests were carried out at a speed of 0.6 m/s and three different loads (60 N, 120 N and 180 N). As a result of the experiments, the tensile strength, modulus of elasticity and hardness of the composite materials produced with the addition of mica filler to the PA6 polymer base matrix increased. In addition, impact strength, wear rate and coefficient of friction values decreased. Moreover, friction coefficient and wear rate values of all materials studied in tribological experiments decreased with increasing load. [ABSTRACT FROM AUTHOR]
