AB  - This research investigates the biocompatibility, mechanical strength, and 
      tribological properties of a hybrid composite material composed of high-density 
      polyethylene (HDPE), hydroxyapatite (HAp), and titanium dioxide nanoparticles (Ti 
      O2). The study explores the microstructural characteristics of the composite 
      material using scanning electron microscopy (SEM), transmission electron 
      microscopy (TEM), and X-ray diffraction (XRD). Samples of HDPE-30%HAp with 
      varying concentrations of Ti O2 (5, 10, 15, and 20%) were prepared and extruded 
      using a twin-screw machine. The hybrid composite materials underwent mechanical 
      tests (tensile, flexural, and hardness), tribological tests (friction and wear 
      rate), and antibacterial tests (resistance to Escherichia coli and Staphylococcus 
      aureus bacteria). The results indicate that the optimal hybrid composite sample 
      was HDPE-30%HAP-10% Ti O2, which demonstrated excellent mechanical properties 
      (maximum tensile strength of 25.93 MPa and young modulus of 480 MPa) and a low 
      coefficient of friction (COF approximately  0.07) while achieving high wear resistance (wear 
      rate in the order of 10-4 m m3N-1 m-1). The study shows that the improvement in 
      mechanical properties results in a corresponding improvement in tribological 
      properties. The antibacterial tests revealed that the hybrid composite material 
      exhibited resistance to E. coli and S. aureus bacteria. The findings of this 
      study suggest that the HDPE-30%HAP-10% Ti O2 composite is a promising material 
      for use in biomedical applications due to its excellent biocompatibility and 
      desirable mechanical and tribological properties. The study demonstrates the 
      potential of reinforced hybrid composite materials in overcoming the 
      disadvantages of monolithic and hybrid micro-composites and highlights the 
      importance of investigating the microstructural, tribological, and mechanical 
      strength characteristics of composite materials for biomedical applications.
