Abstract
Despite their many similarities, natural fibers have superior mechanical
properties to synthetic fibers, including higher ultimate strength, greater
elongation, resistance to ethering, biodegradability, lightweight, and fewer
toxications. The mechanical characteristics of several matrices reinforced with
synthetic and hemp fibers were examined in the current paper. We made the
various hemp composites using vinyl ester, cellulose acetate (CA), treated CA,
and GFRP (glass fiber-reinforced polymer) with CA. Composites were examined for
mechanical characteristics such as tensile, flexural, impact, and hardness.
Composites have a density of 1.19 g/cm3. Hemp with vinyl ester has
higher tensile strength and flexural properties than other composites, but in
impact, GFRP with CA has more impact strength of nearly 400 J/m, so for making
eco-friendly biocomposite for lightweight structural applications.
尽管天然纤维与合成纤维有许多相似之处，但天然纤维的机械特性却优于合成纤维，包括更高的极限强度、更大的伸长率、抗醚化能力、生物降解性、轻质和较少的毒性。本文研究了几种用合成纤维和麻纤维增强的基材的机械特性。我们使用乙烯基酯、醋酸纤维素（CA）、处理过的 CA 和带有 CA 的 GFRP（玻璃纤维增强聚合物）制作了各种麻复合材料。对复合材料的拉伸、弯曲、冲击和硬度等机械特性进行了检测。复合材料的密度为 1.19 克/立方厘米。含乙烯基酯的大麻比其他复合材料具有更高的拉伸强度和弯曲性能，但在冲击方面，含 CA 的玻璃纤维增强聚合物具有更高的冲击强度，接近 400 J/m，因此可用于制造环保型生物复合材料，用于轻质结构应用。
