摘要
传统金属材料虽具有良好的机械性能,但存在质量大、易腐蚀等问题,难以满足现代农机具在高效率与节能环保方面的综合性能需求。本文围绕农机具用复合材料的制备工艺与性能开展研究,选取碳纤维增强树脂基复合材料与玻璃纤维增强材料作为主要研究对象,分别采用模压、缠绕、热压等工艺进行成型,系统测试了其力学性能、耐腐蚀性能及环境适应性。研究结果表明,复合材料在保持良好强度和刚度的同时,具有显著的减重效果,且在酸碱土壤环境中表现出优异的耐蚀稳定性。研究结果旨在为农机具轻量化与高性能化提供了材料技术支撑,也为复合材料在农业装备中的产业化应用奠定了理论基础。
Due to the significant differences between composites and metals in terms of coefficient of thermal expansion,modulus of elasticity,etc.,traditional riveting,screwing and other methods are prone to lead to stress concentration,material peeling or fatigue failure at the connection.Future research needs to focus on high-strength,environmentally friendly,easy-to-maintain heterogeneous materials connection technology,such as structural adhesive bonding,nested structures,composite sandwich design and other new connection forms.At the same time,for the inevitable wear and tear and damage of agricultural machinery in the field in the long-term operating environment,the research should focus on the online detection of composite structures and damage self-repair mechanism.
