Abstract
Novel hybrid composites of thermoplastic polyamide 6 (PA6), 5 wt% glass fibers (GFs), and hexagonal boron nitride (hBN) filler at 0.5, 1, and 3 wt% were prepared by injection molding. Structural, physical, and mechanical characteristics of the composites were assessed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), water contact angle (WCA), Rockwell hardness, and tensile tests, respectively. Tribological [coefficient of friction (COF)] and wear characteristics were determined at room temperature (25 °C) through a wear test using a pin-on-disc (POD) apparatus operating at various sliding velocities (viz., 200, 400, and 800 rpm), normal loads (viz., 10, 20, and 30 N), and time periods (viz., 30, 45, and 60 min). Furthermore, surface morphology of the worn samples and the wear mechanisms of the composites were also investigated using vision machine, scanning electron microscopy (SEM), and optical microscopy. The worn samples S3 (30 min/30 N/800 rpm), S6 (45 min/30 N/200 rpm), and S9 (60 min/30 N/400 rpm) showed better wear resistance properties through adhesive wear mechanism. Here, PA6/5GF/1hBN showed highest hardness of 51.33 HRF as well as elongation (350%) with adequate strength 50.6 MPa and hydrophobicity (104°) owing to the lowest particles or fibers debonding. The overall tribological (42% and 35% decrease in coefficient of friction and specific wear rate, respectively) and mechanical (13.6% hardness, 13.8% tensile strength and 1300% elongation increased) properties of PA6/5GF/hBN hybrid nanocomposites at 1 wt% hBN, significantly improved compared to our other developed PA6/5GF/hBN composites.
