摘要

该生物复合材料除在海洋或水下应用外，具有多种多样的应用。在这项工作中，我们试图预见以聚乳酸(PLA)为主要成分和天然可生物降解纤维(柠檬皮、甜酸橙皮、土豆皮和洋葱皮)构建的生物复合材料。本课题旨在利用ANSYS Workbench建立以天然纤维增强PLA为基材的层压板结构模型。采用单次冲击、均匀压力、影响球吸能等参数进行了仿真试验。天然纤维复合材料的体积分数分别为10%、20%和30%，以达到最佳效果。采用显式动力学分析作为求解器进行计算分析，并利用ANSYS Workbench中的设计建模器建立了冲击分析器的模型。模拟结果被考虑用于进一步的实验测试，作为ASTM D7136中提到的分析计算的未来工作。

Impact Analysis of Bio-composite Laminate for Low and Intermediate Velocity Application

The bio-composite materials are compatible with many diversified applications except in marine or submerged instances. An attempt is made in this work to foresee the bio-composite built with Poly Lactic Acid (PLA) as a principal constituent and natural biodegradable fibres (peels of lemon, sweet lime, potato and onion). The project is aimed to build the laminate structure model with the substrate as PLA reinforced with natural fibres using ANSYS Workbench. The simulation test was carried out with various parameters: single impact, uniform pressure, sphere of influence energy absorption. Natural fibre composites were built with a volume fraction of 10%, 20% and 30% of PLA to arrive at optimum results. The computation analysis was carried out using explicit dynamic analysis as a solver and a model of impact analyser was built-in design modeller that is available in ANSYS Workbench. The simulation results are considered for further experimental testing as future work with analytical calculations referred to in ASTM D7136.
