The research aimed to determine how hydroxyapatite (HA) influences impact resistance, wear adhesion and toughness in high-density polyethylene (HDPE)-biocomposites. Hydroxyapatite derived from eggshells underwent grinding, phosphating, and calcination processes. Characterization of the resulting powder involved Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TG), and X-ray Diffraction (XRD) to identify characteristic functional groups, chemical stability, diffraction angles, and corresponding crystallographic planes, confirming the composition as hydroxyapatite. Biocomposites containing HDPE as matrix and HA as reinforcement at 10, 20, 30 and 40% by weight, through the extrusion process at a temperature of approximately 220°C using a laboratory single-screw extruder. the samples without HA filler. The best results achieved in the case of the addition of 20% by weight of HA in the biocomposite, with an impact resistance of 23.057 KJ/m2, which represents a 127% increase, as well as a reduced wear with a decrease in mass loss of 0.367g, representing a reduction of 83%, and a higher toughness with a value of 19.767 Shore D, showing a 17% increase with respect to Therefore, it was found that the addition of hydroxyapatite in the biocomposite improves the properties of impact resistance, wear adhesion and toughness, with an optimum addition percentage of 20% by weight.
