The objective of this study is to examine the mechanical properties and surface characteristics of composites with antibacterial potential, specifically those based on structural polyoxymethylene and titanium oxide. The nanocomposite was modified through the incorporation of commercially available impact modifiers derived from high-molecular weight silicones, as well as aramid fibers with a compatibilizer of ethylene-n-octene grafted with maleic anhydride (EOC-g_MAH). Fundamental strength and low-cycle tests were conducted to ascertain the dissipation energy of the material, and assessments of surface tension and contact angle were performed. The inclusion of silicone was found to diminish the strength properties, yet it positively influenced the release and surface tension of the material. In contrast, aramid fibers enhanced impact strength while reducing the contact angle of the surface by approximately 6%.
