A composite material was prepared using epoxy as a matrix, and carbon fiber (20% volume fraction) together with nano titanium dioxide (TiO₂) particles in varying weight fractions (0,2,4 and 6%) as hybrid reinforcement. Mechanical tests (impact strength and wear resistance) were carried out, in addition to the study of liquid uptake behavior during immersion in chemical solutions, and inspection with scanning electron microscope imaging to reveal the microscopic details. The results showed that the addition of TiO₂ have improved the mechanical properties of the composites, as the specimen reinforced with 4% TiO₂ showed the highest impact strength, in addition to improved wear resistance. The scanning electron images for the specimens showed finely dispersed carbon fibers surrounded by the ultrafine TiO₂ nano powder, suggesting a uniform distribution of reinforcement throughout the whole matrix for all the prepared specimens. The liquid uptake results showed that the specimen reinforced with 20% carbon fibers and 6% nano TiO₂ had the highest diffusion rate, especially when immersed in hydrochloric acid. The results show that the prepared composite could be a good alternative to traditional materials whenever good wear resistance is involved, together with impact and chemical resistance, such as in anti-skid flooring applications.

使用环氧树脂作为基质，以碳纤维（体积分数为20％）和不同重量分数（0、2、4和6％）的纳米二氧化钛（TiO ₂）颗粒作为复合增强材料，制备了复合材料。除了研究浸入化学溶液过程中的液体吸收行为外，还进行了机械测试（冲击强度和耐磨性），并用扫描电子显微镜成像检查了微观细节。结果表明，TiO ₂的添加改善了复合材料的力学性能，因为用4％TiO ₂增强了样品除了改善的耐磨性外，还显示出最高的冲击强度。样品的扫描电子图像显示被超细TiO ₂纳米粉末包围的细分散的碳纤维，这表明所有制备的样品在整个基体中均具有均匀的增强分布。液体吸收结果表明，用20％碳纤维和6％纳米TiO ₂增强的样品具有最高的扩散速率，尤其是当浸在盐酸中时。结果表明，只要涉及到良好的耐磨性以及抗冲击性和耐化学性，例如在防滑地板应用中，制备的复合材料就可以很好地替代传统材料。
