This work reports a poly(butylene succinate) (PBS) biocomposite modified by amino functionalized ramie fiber fabric (RFF) via a facile thermal-compressive method. Different from other methods, we introduced PBS nonwoven as matrix raw material, whose three-dimensional network structure can effectively anchor RFF, resulting in excellent infiltration. Results show that the mechanical performance, wettability, crystallization behavior, thermal performance, rheological behavior as well as biodegradability of PBS biocomposite are competitive with the introduction of amino functionalized RFF. Compared with RFF/PBS biocomposites fabricated in other researches, there is a significant promotion in mechanical performance. For RFF/PBS-50 wt% biocomposite, the tensile strength, elongation at break, flexural strength, flexural modulus, interlaminar shear strength (ILSS) and impact strength reach to 72.4 MPa, 19.4%, 100.5 MPa, 4.9 GPa, 3.3 MPa and 67.5 KJ/m², respectively. They are mainly ascribed to observed excellent interfacial bonding, typical plastic deformation of PBS and riveting effect of RFFs. Furthermore, the RFF/PBS biocomposite shows favorable biodegradability in the compost test. The biodegradable function of RFF/PBS biocomposite enables it to become a desirable substitute of conventional nondegradable composite.

这项工作报告了一种由氨基官能化麻纤维织物（RFF）通过一种简便的热压方法改性的聚丁二酸丁二酯（PBS）生物复合材料。与其他方法不同，我们引入了PBS非织造布作为基质原料，其三维网络结构可以有效地锚固RFF，从而获得出色的渗透性。结果表明，PBS生物复合材料的机械性能，润湿性，结晶行为，热性能，流变行为以及生物降解性与引入氨基官能化的RFF具有竞争性。与其他研究中制造的RFF / PBS生物复合材料相比，机械性能有了显着提升。对于RFF / PBS-50 wt％生物复合材料，其拉伸强度，断裂伸长率，弯曲强度，弯曲模量，²，分别。它们主要归因于观察到的优异的界面结合，PBS的典型塑性变形和RFF的铆接效果。此外，RFF / PBS生物复合材料在堆肥测试中显示出良好的生物降解性。RFF / PBS生物复合材料的可生物降解功能使其能够成为常规不可降解复合材料的理想替代品。
