Bio-based composites provide an improved sustainability and carbon footprint compared to conventional composites. In this context, this study aims in developing and characterizing green composites using a novel natural fibers-fabric formed by interconnected network of fibers struts with intricate structures isolated from Opuntia (Cactaceae) as reinforcing agent in bio-based composites. Two thermoplastic polymers, which were polyvinyl alcohol and styrene-butadiene rubber, were used as the matrices. Composites with 3, 6 and 9 % (w/w) fibrous networks were produced and characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). The DMA was performed to determine the thermomechanical and viscoelastic properties according to the orientation distribution of the fibers. The properties of bio-based materials changed systematically, depending on the direction of axial fibers in the network and showing anisotropy of the material. Then, the dimensional properties and biodegradability in soil burial of the bio-based composites were investigated. The good interfacial interaction between the fiber and the polymer enhanced the composite performance, especially with respect to the thermal and thermomechanical properties as well as biodegradability.

与传统的复合材料相比，生物基复合材料具有更好的可持续性和碳足迹。在这种情况下，本研究旨在开发和表征绿色复合材料，其使用一种新颖的天然纤维织物，该织物由与仙人掌分离的复杂结构的纤维撑杆相互连接的网络形成（仙人掌科）作为生物基复合材料的增强剂。两种热塑性聚合物分别为聚乙烯醇和丁苯橡胶。制备了具有3％，6％和9％（w / w）纤维网络的复合材料，并通过扫描电子显微镜（SEM），热重分析（TGA），差示扫描量热法（DSC）和动态力学分析（DMA）对其进行了表征。根据纤维的取向分布进行DMA以确定热机械和粘弹性能。生物基材料的特性会根据网络中轴向纤维的方向进行系统更改，并显示出材料的各向异性。然后，研究了生物基复合材料在土葬中的尺寸特性和可降解性。
