Unsaturated polyester resin (UPR) is one of the first commercialized polymer matrices for composites reinforced with glass fibers, but has remained popular to this day. To reduce their environmental impact, natural fibers have been used as reinforcements. Researchers all over the world are still interested in these composites, and numerous papers have been published in the last four decades. Using bibliometric analysis, this work provides compiled, structured, and relevant information about the evolution and current state of these materials. This first study on UPR biocomposites based on bibliometric analysis examined 531 published papers identified in the Scopus database from 1982 to July 2022. An analysis of the most active states, leading institutions, and leading authors is followed by the identification of key areas such as the most common natural fibers used as reinforcements, fiber treatments, and composite design parameters such as processing techniques; recently, composite testing; and technological applications. The findings emphasize the importance of staying active in this global field and provide information on novel promising topics for future research.
不饱和聚酯树脂（UPR）是最早商业化的用于玻璃纤维增强复合材料的聚合物基体之一，至今仍广受欢迎。为了减少对环境的影响，天然纤维已被用作增强材料。世界各地的研究人员仍然对这些复合材料感兴趣，在过去四十年里发表了大量论文。通过文献计量分析，这项工作提供了有关这些材料的发展历程和当前状态的汇编、结构化且相关的信息。这项基于文献计量分析的关于UPR生物复合材料的首次研究，考察了1982年至2022年7月在Scopus数据库中识别出的531篇已发表论文。在分析最活跃的国家、领先机构和主要作者之后，确定了关键领域，如用作增强材料的最常见天然纤维、纤维处理以及复合材料设计参数（如加工技术）；近期的复合材料测试；以及技术应用。研究结果强调了在这一全球领域保持活跃的重要性，并提供了关于未来研究新的有前景主题的信息。
