Experimental investigation and mathematical modeling of carbon nano tube and boron nitride nano particulated reinforced carbon / epoxy nanocomposites

In this thesis, different amounts of carbon nanotube (KNT) and boron nitride (BN) reinforced carbon fabric epoxy materials were produced and the tensile strength and tribological properties of the obtained materials were examined according to ASTM standards. Tensile tests were carried out according to ASTM D 3039 standards and KNT reinforced materials had the highest tensile strength of 1% KNT. This was followed by material with 2% KNT and 0,5% KNT respectively. Also compared to the tensile experiments of materials containing 1% nanoparticle inside; The sample containing 1% KNT has the highest tensile strength. This was followed by the tensile strength of the material containing 0,5% (KNT + BN) and 1% BN, respectively. In the tensile test, each material containing nanoparticles was more resistant than pure material without nanoparticles. The abrasion tests of the produced samples according to ASTM G133 were performed and their tribological properties were examined from two different angles. first point of view: experimental design methods (DOE), response surface methodology (RSM) and the predetermined speed (m / s) and loads (N) of the input parameters and predetermined wear and abrasion amount (gr) depending on the output parameters 13 different experiments were performed for each material. The second perspective; tribological properties of materials under constant velocity (2m / s) and constant load (20N) were examined and compared. Comparing composites containing KNT under constant load (N) and velocity (m / s); the lowest mean μ value was obtained in composites containing 1% KNT. This was followed by carbon composite containing pure carbon composite, 0,5% KNT and 2% KNT, respectively. When compared to composites containing 1% nano particles; nano carbon composites containing the lowest 1% KNT followed by nano composites containing pure carbon composite and 1% BN and 0,5% (KNT + BN). Despite the high wear coefficients, the lowest amount of wear was observed in the composite containing 0,5% KNT. This was followed by nano-composite containing 2% KNT and nano-composite containing 0,5% (KNT + BN). The highest amount of wear occurred in the pure carbon composite. In this case, the nanoparticles can significantly reduce the amount of wear on the surface of the composites and can be obtained at low or high values depending on the place of use.
