Fiber‐reinforced polypropylene (PP) composites are widely used for structural bearing because of their excellent mechanical property. So, it is necessary to improve the mechanical property of fiber‐reinforced PP composites. In this present, two‐dimensional Ti3C2 Mxene nanosheets were bound to short aramid fiber (SAF), forming Ti3C2 nanosheets‐modified SAF (Ti3C2/SAF), aiming to improve PP mechanical property. The Ti3C2 nanosheets were obtained after hydrofluoric acid etching and ultrasonically delamination procedure, followed by chemically bound to the surface of H3PO4 solution‐treated SAF to form Ti3C2/SAF. The Ti3C2/SAF‐reinforced PP (Ti3C2/SAF/PP) composites were prepared by a melt blending method. Scanning electron microscopy images showed that the Ti3C2/SAF modified with different concentration of Ti3C2 nanosheets solution presented the distinct morphologies, with the 0.3 mg/ml Ti3C2/SAF formed a relatively uniform Ti3C2 nanosheets coating on the SAF surface. Test results of mechanical performance indicated that the tensile and impact strength of Ti3C2/SAF/PP composites were significantly improved. Especially, the maximum tensile and impact strength of 0.3 Ti3C2/SAF/PP composite at 5 wt% reached to 37.8 MPa and 14.0 kJ/m2, which was increased by 11.5% (or 28.1%) in tensile strength and 12.9% (or 38.6%) in impact strength, compared with that of SAF/PP composite (or PP matrix). This can be attributed that Ti3C2 nanosheets binding to SAF improved the interfacial bonding strength between SAF and PP. This work provides a promising strategy for improving the mechanical properties of fiber‐reinforced PP composites.

Ti3C2甲苯纳米片改善了短芳纶纤维增强聚丙烯复合材料的机械性能
纤维增强聚丙烯（PP）复合材料因其优异的机械性能而广泛用于结构轴承。因此，有必要提高纤维增强PP复合材料的机械性能。在目前，二维Ti 3 C 2 Mxene纳米片被绑定到短芳纶纤维（SAF），形成Ti 3 C 2纳米片改性的SAF（Ti 3 C 2 / SAF），旨在提高PP的机械性能。经过氢氟酸蚀刻和超声分层程序，然后化学键合到H 3 PO 4表面上，获得了Ti 3 C 2纳米片。固溶SAF形成Ti 3 C 2 / SAF。Ti 3 C 2 / SAF增强的PP（Ti 3 C 2 / SAF / PP）复合材料是通过熔融共混法制备的。扫描电子显微镜图像显示，用不同浓度的Ti 3 C 2纳米片溶液改性的Ti 3 C 2 / SAF表现出明显的形貌，其中0.3 mg / ml Ti 3 C 2 / SAF形成相对均匀的Ti 3 C 2。在SAF表面上涂覆纳米片。力学性能测试结果表明，Ti 3 C 2 / SAF / PP复合材料的拉伸强度和冲击强度均有明显提高。尤其是，在5 wt％时0.3 Ti 3 C 2 / SAF / PP复合材料的最大拉伸和冲击强度达到37.8 MPa和14.0 kJ / m 2，拉伸强度和12.9分别提高了11.5％（或28.1％）。相较于SAF / PP复合材料（或PP基体）的冲击强度，提高了5％（或38.6％）的冲击强度。这可以归因于Ti 3 C 2纳米片与SAF的结合提高了SAF和PP之间的界面结合强度。这项工作为改善纤维增强PP复合材料的机械性能提供了一种有前途的策略。
