Abstract Cardanol is a novolac phenolic resin derived from cashew nutshell liquid (CNSL) with low mechanical properties due to its high brittleness. It is a potential resin for aerospace industry due to its high thermal resistance. In this study, to enhance the mechanical properties of cardanol, it was hybridized with kenaf/recycled carbon to produce biodegradable composites. The mechanical properties (tensile, flexural, and impact strength) of the hybrid composites were determined as per ASTM standards. The scanning electron microscopy (SEM) of tensile fracture samples were also analyzed. The mechanical results indicate that the hybridization enhances the mechanical strength of the cardanol significantly. The enhancement in tensile strength is 129.7% when cardanol was reinforced with 35wt. % kenaf and 15wt. % carbon. While flexural and impact strength were improved by 37.6% and 104% respectively both when cardanol was hybridized with 15wt. % kenaf and 35wt. % carbon The morphology study suggests that the carbon acts as a layer at the bottom of the mold due to its inhomogeneity and sedimentation.

通过与红麻/再生碳杂交增强腰果酚的机械性能

摘要 腰果酚是一种源自腰果壳油 (CNSL) 的酚醛树脂，由于其脆性高，机械性能较差。由于其高耐热性，它是航空航天工业的潜在树脂。在这项研究中，为了提高腰果酚的机械性能，将其与洋麻/回收碳混合以生产可生物降解的复合材料。混合复合材料的机械性能（拉伸、弯曲和冲击强度）根据 ASTM 标准确定。还分析了拉伸断裂样品的扫描电子显微镜（SEM）。力学结果表明，杂交显着提高了腰果酚的机械强度。当腰果酚用35wt％增强时，拉伸强度提高了129.7%。% 红麻和 15wt. ％ 碳。当腰果酚与 15wt.% 混合时，弯曲强度和冲击强度分别提高了 37.6% 和 104%。% 红麻和 35wt. % 碳 形态学研究表明，碳由于其不均匀性和沉降性而在模具底部充当一层。
