ABSTRACT

The application suitability of natural fibers is increased by the method of hybridization. The current study deals with the development and characterization of four different tri-layer composites by varying the stacking sequence of Parthenium hysterophorus and Impomea pes-caprae fibers with epoxy as a matrix, by using the conventional hand layup process. The mechanical properties, namely tensile, flexural, impact, Shore D hardness, and water absorption properties, were analyzed as per ASTM. The test results show that composites with upper layers of Impomea pes-caprae and a core layer of Parthenium hysterophorus fibers showed enhanced mechanical properties and reduced water absorption, thereby proving its suitability for lightweight medium load applications. Morphological studies using Scanning Electron Microscope elucidated the fiber bonding and void characteristics of the tested composites.

摘要

通过杂交方法提高了天然纤维的应用适应性. 本研究以环氧树脂为基体,采用传统的手糊工艺,通过改变Parthenium Herosphorus和阳萎pes caprae纤维的堆积顺序,制备了四种不同的三层复合材料. 力学性能,即拉伸性能、弯曲性能、冲击性能、肖氏硬度和吸水性能,按ASTM标准进行了分析. 试验结果表明,以阳萎皮为上层,以党参为芯层的复合材料,其力学性能得到提高,吸水率降低,从而证明其适用于轻量化中等负荷应用. 用扫描电子显微镜进行的形态学研究阐明了被测复合材料的纤维结合和空洞特性.
