This review article focuses on the long-term durability challenges associated with bamboo fiber-reinforced polymer composites when subjected to various environmental aging conditions such as water immersion, hygrothermal fluctuations, ultraviolet (UV) radiation, soil burial, and refrigerated storage. The primary issue addressed is the degradation of mechanical and structural performance of bamboo fiber-reinforced polymer composites due to moisture absorption, fiber swelling, and fiber-matrix interface deterioration. To mitigate these aging effects, the study evaluates and compares multiple strategies, including chemical and physical fiber surface treatments, filler additions, and fiber hybridization, which aim to enhance moisture resistance and mechanical stability. These composites are relevant in automotive interiors, construction panels, building insulation, and consumer goods due to their eco-friendly nature and potential to replace conventional synthetic composites. This review is necessary to consolidate current knowledge, identify effective enhancement approaches, and guide the development of environmentally resilient bamboo fiber-reinforced polymer composites for real-world applications.
本文综述聚焦于竹纤维增强聚合物复合材料在诸如水浸、湿热波动、紫外线（UV）辐射、土壤掩埋和冷藏储存等各种环境老化条件下所面临的长期耐久性挑战。所探讨的主要问题是由于吸湿、纤维膨胀以及纤维 - 基体界面劣化导致竹纤维增强聚合物复合材料的机械和结构性能退化。为减轻这些老化影响，该研究评估并比较了多种策略，包括化学和物理纤维表面处理、添加填料以及纤维混杂，这些策略旨在提高耐湿性和机械稳定性。由于其环保特性以及替代传统合成复合材料的潜力，这些复合材料在汽车内饰、建筑板材、建筑保温和消费品领域具有相关性。此综述对于巩固现有知识、确定有效的增强方法以及指导开发适用于实际应用的环境适应性强的竹纤维增强聚合物复合材料而言是必要的。
