Polymers constitute the most employed reinforced matrices to achieve composite materials. Carbon and glass fibers are the reinforcements that are mainly utilized to improve specific properties for both thermoplastics and thermosets creating a new class of materials, which has been applied in several industrial fields. Various products made of fiber reinforced polymers are available on the market and at their own end-of-life, they must be reclaimed and remanufactured, properly, in an ideal recycling circular economy. The aim of this review is to point out the progress on fiber reclaiming from these materials, providing an overview on the most employed strategies and highlighting their main technological limits. Specifically, first, mechanical, thermal and chemical reclaiming processes have been contextualized introducing their peculiarities. Subsequently, the attention has been focalized on the new research trends proposed in the last years showing the direction, where the research is moving to. The processes have been also classified in terms of tensile strength of the reclaimed fibers and in terms of the energy required to be performed. Finally, design for reclaiming and remanufacturing treatments have been also considered pointing out the different approaches that can be pursued as valuable solutions to strengthen the recycling capabilities encouraging as much as possible the recovering of the polymeric matrix composites.

聚合物构成了实现复合材料最常用的增强基质。碳纤维和玻璃纤维是增强材料，主要用于改善热塑性塑料和热固性塑料的特定性能，创造了一类新的材料，已应用于多个工业领域。市场上有各种由纤维增强聚合物制成的产品，在其使用寿命结束时，必须在理想的循环经济中进行适当的回收和再制造。本综述的目的是指出从这些材料中回收纤维的进展，概述最常用的策略并强调它们的主要技术限制。具体来说，首先，机械、热和化学回收过程已被背景化，介绍了它们的特点。随后，注意力集中在过去几年提出的新研究趋势上，显示了研究的方向。这些过程还根据再生纤维的拉伸强度和所需的能量进行了分类。最后，还考虑了回收和再制造处理的设计，指出了不同的方法，这些方法可以作为加强回收能力的有价值的解决方案，鼓励尽可能多地回收聚合物基复合材料。这些过程还根据再生纤维的拉伸强度和所需的能量进行了分类。最后，还考虑了回收和再制造处理的设计，指出了不同的方法，这些方法可以作为加强回收能力的有价值的解决方案，鼓励尽可能多地回收聚合物基复合材料。这些过程还根据再生纤维的拉伸强度和所需的能量进行了分类。最后，还考虑了回收和再制造处理的设计，指出了不同的方法，这些方法可以作为加强回收能力的有价值的解决方案，鼓励尽可能多地回收聚合物基复合材料。
