In this experimentation hybrid composites using natural fibers and titanium oxide (TiO₂) nano filler were fabricated using compression moulding technique. Pineapple (P) and Sisal (S) fibers were used as the natural reinforcements with epoxy as the matrix material. The mechanical results of flexural, impact and tensile properties found good improvement in the properties with SP fiber reinforcement (1:1 ratio) and TiO₂ filler addition. The combination with 40 wt.% SP/5 wt.% TiO₂ observed better mechanical results. The Taguchi optimization results showed lower Specific Wear Rate (SWR) by the incorporation of high TiO₂ filler (5 wt.%) addition with the polymer-based composites. The filler substitutes replace the vacant space between fiber/matrix phase and add to the properties. The multi response optimization with TOPSIS proved that hybrid SP has the high influence in overall tribological properties of the natural fiber composites with rank 1 followed by filler incorporation. The results showed combination with 5 wt.% TiO₂/20 wt.% SP Hybrid fiber/500 m Sliding distance/Sliding speed of 1 m/s and applied load of 5 N having optimized results.

在该实验中，使用压缩成型技术制造了使用天然纤维和氧化钛 (TiO ₂ ) 纳米填料的混合复合材料。菠萝（P）和剑麻（S）纤维被用作天然增强材料，环氧树脂作为基质材料。弯曲、冲击和拉伸性能的机械结果发现，使用 SP 纤维增强材料（1:1 比例）和 TiO ₂填料添加后，性能得到了很好的改善。与 40 wt.% SP/5 wt.% TiO _{2 的组合}观察到更好的机械结果。田口优化结果表明，通过掺入高 TiO _{2 可}降低比磨损率 (SWR)填料 (5 wt.%) 添加与聚合物基复合材料。填料替代物取代了纤维/基体相之间的空隙并增加了性能。使用 TOPSIS 进行的多响应优化证明，混合 SP 对天然纤维复合材料的整体摩擦学性能有很大影响，等级为 1，然后是填料掺入。结果表明，与 5 wt.% TiO ₂ /20 wt.% SP 混合纤维/500 m 滑动距离/1 m/s 滑动速度和 5 N 施加载荷的组合具有优化的结果。
