摘要

为了提高复合材料的性能,我们制作了由鹅掌楸和印度杏仁等纤维组成的混合复合材料,并添加了枣果籽颗粒等天然填料。研究了酸枣仁颗粒和分层顺序对复合材料机械性能、吸水性和生物降解的影响。最初,采用手工分层法,改变纤维的分层顺序,生产出两种类型的复合材料:IA/P/IA(印度杏仁/柚子/印度杏仁)和 P/IA/P(柚子/印度杏仁/柚子)。根据拉伸测试结果,P/IA/P 复合材料因高强度柚木纤维的密集堆积而成为最佳选择。随后,在 P/IA/P 复合材料中加入了枣核颗粒,重量百分比从 2.5 到 10 不等,步长为 2.5。研究了枣核颗粒对 P/IA/P 复合材料性能的影响。P/IA/P/7.5 wt%的红枣复合材料表现出优异的拉伸、弯曲、冲击和硬度性能,记录值分别为 82 MPa、98 MPa、5.2 kJ m-2 和 86 shore-d。这些数值分别比 P/IA/P 复合材料高出 15.4%、22.5%、20.9% 和 4.8%。P/IA/P/10 wt% 红枣复合材料的吸水率极低,12 天内仅为 8%,质量损失也很有限,60 天内共损失 27%。因此,这项研究表明,P/IA/P/7.5 wt% 复合材料在工业应用中大有可为。

Effect of layering sequence and jujube fruit seed addition on the mechanical, water absorption and bio-degradation properties of Indian almond/peepal hybrid composites
Hybrid composite comprised fibers like peepal and Indian almond was fabricated, with the addition of natural filler such as jujube fruit seed particles aimed at enhancing composite performance. The impact of jujube fruit seed particles and layering sequence on the mechanical properties, water absorption and bio-degradation of the composites was investigated. Initially, two composite types, IA/P/IA (Indian almond/Peepal/Indian almond) and P/IA/P (Peepal/Indian almond/Peepal), were produced using hand layup practice, altering layering sequence of fibers. Based on tensile test results, the P/IA/P composite emerged as the optimal choice due to the denser packing of high-strength peepal fiber. Subsequently, jujube fruit seed particles were incorporated into the P/IA/P composite at varying weight percentages ranging from 2.5 to 10 with a step size of 2.5. The effect of jujube fruit seed particles on the performance of the P/IA/P composite was examined. The P/IA/P/7.5 wt% jujube composite demonstrated superior tensile, flexural, impact, and hardness properties, recording values of 82 MPa, 98 MPa, 5.2 kJ m−2, and 86 shore-d, respectively. These values were 15.4%, 22.5%, 20.9%, and 4.8% higher than those of the P/IA/P composite. The P/IA/P/10 wt% jujube composite demonstrated minimal water absorption, with only 8% recorded over a 12-day period, as well as limited mass loss, totaling 27% over 60 days. Consequently, this research suggests that the P/IA/P/7.5 wt% composite holds promise for industrial applications.
