OBRABOTKAMETALLOV MATERIAL SCIENCE Vol. 27 No. 1 2025 Conclusion This study highlights the advanced properties of 10 wt. % PEEK in Acrylate composites biomaterials, demonstrating their enhanced wear resistance and improved mechanical properties compared to Acrylate composites with lower PEEK content and base Acrylate materials. – The 10 wt. % PEEK in Acrylate composites biomaterial possesses an optimal balance of strength, stiffness, and ductility, which is critical for load-bearing applications such as orthopedic implants. Pin-on-disc wear tests showed a significant reduction in the specific wear rate of the 10 wt. % PEEK in Acrylate composite at various loads and speeds, confirming its suitability for use in high-stress environments. – SEM and EDS studies confirmed the uniform distribution of PEEK particles within the polymer matrix, which ensures improved mechanical properties and durability of the composite material. – The ability of the 10 wt. % PEEK in Acrylate composite to maintain mechanical integrity under harsh tribological conditions makes it a promising material for long-term applications in orthopedics, particularly in joint implants where wear resistance and mechanical characteristics are crucial for successful implantation. – The improved wear resistance and enhanced mechanical strength of this composite reduce the risk of implant failure due to material degradation, which is an important factor determining the lifespan of hipjoint implants. – The 10 wt. % PEEK in Acrylate composite biomaterial can be processed using DLP 3D-printing at room temperature, and the resulting products are suitable for the fabrication of biomedical implants, prosthetic implants, tissue engineering scaffolds, and other healthcare applications. However, further research is needed to fully understand the behavior of these composite materials in realistic clinical conditions. – Future studies should focus on fatigue testing to evaluate the material’s durability under cyclic loading conditions that simulate the loads experienced by implants installed within the human body. – In addition, clinical trials are needed to confirm the biocompatibility and performance of this material over extended periods.
