Abstract: DEVELOPMENT OF WEAR-RESISTANT LIGHT-WEIGHT AL-BASED HYBRID NANOCOMPOSITES FOR AEROSPACE LANDING GEAR APPLICATIONS Abstract A lightweight, high-strength, and wear-resistant aluminium-based hybrid nanocomposite material and an optimized low-temperature spark plasma sintering method for its fabrication are disclosed for high- wear aerospace structural applications. The hybrid nanocomposite comprises a high-purity aluminium metal matrix reinforced with a ternary hybrid nanofiller system consisting of multi-walled carbon nanotubes (MWCNTs), graphite nanoplatelets (GnPs), and hexagonal boron nitride (hBN). The multi-walled carbon nanotubes act as mechanical bridging strands that link planar surfaces of the graphite nanoplatelets and hexagonal boron nitride sheets, establishing an interconnected three-dimensional reinforcing nano- architecture that prevents filler agglomeration and reduces internal porosity down to approximately 3.7%. Consolidating the composite via spark plasma sintering at a low temperature of 400°C and 50 MPa pressure for 10 minutes prevents the formation of brittle intermetallic aluminium carbide (Al_4C_3) phases. Under dry sliding friction, the composite forms a protective, self-lubricating tribo- layer that cuts the volumetric wear rate by approximately 70%, stabilizes the coefficient of friction between 0.55 and 0.60, limits wear depth penetration to under 120 mu m, and changes the primary wear mechanism from severe delamination to mild ploughing.
