Glass filled nylon composites (GFN) and hybrid graphene oxide reinforced glass filled Nylon nanocomposites (GO-GFN) are prepared by blending the required base materials in injection molding machine at processing temperature of 275°C. The specimens prepared are subjected to various mechanical property tests to reveal their hardness, tensile strength and flexural strength. The wear discs of GFN and GO-GFN composites as per ASTM standard are injection molded to analyze the tribological properties using pin on disc tribometer. The pin used is EN 8 Tool steel. The Coefficient of friction for the GFN composites for the wear load of 10 N is 0.28. Addition of 0.003 wt% GO to the GFN system has decreased the coefficient of friction significantly to the value of 0.12. The decrease in C.O.F was correlated with the adhesion film formation in the pin surface. This work confirms the improvement in wear resistance of GO-GFN system which is attributed by the presence of graphene oxide only.

In this work, the synergistic effect of graphene oxide and nanozirconia on the flexural and tribological properties of basalt fiber/epoxy composites was investigated. At the first step, the nanofillers were surface-modified to improve their compatibility with the epoxy matrix. Then, several laminates were fabricated by varying the filler loading. The results revealed that the multiscale composite filled with 0.1 wt.% graphene oxide + 1 wt.% nanozirconia exhibited the maximum flexural strength and wear resistance. Compared to the neat basalt fiber/epoxy composite, the wear rate and friction coefficient of the 0.1 wt.% graphene oxide + 1 wt.% nanozirconia-filled specimen were decreased by 67 and 62%, respectively, whereas the flexural strength was enhanced by 50%. Scanning electron microscopy analysis clearly showed an enhanced fiber-matrix interfacial bonding for the multiscale composite containing hybrid fillers in the matrix.

The Coefficient Of Friction

The aim of the work was to examine properties of hybrid composites reinforced with basalt fiber (BF) and polytetrafluoroethylene (PTFE) particles based on a polyoxymethylene matrix modified by silicon oil. In the experimental part the basic physico-mechanical properties were determined. Thermal and tribological properties were also investigated. To refer to the effects of reinforcement and determine the structure characteristics SEM images were taken. The addition of basalt fibers and PTFE particles in the amount of 7.5/7.5 wt% reduces the coefficient of friction (from 0.36 to 0.12) and the wear rate (from 0.61 to even 0.37) in relation to neat POM and increases the strength properties. An increase in the filler content to 12.5/12.5 wt% results in an almost twofold raise in stiffness from 2800 MPa to 5120 MPa for tensile, and from 2500 to 4944 MPa for flexural and causes a further reduction in wear rate without affecting on the friction coefficient. Studies have shown that the addition of filler allows to provide excellent tribological properties while maintaining high strength properties.
