Embedding of fibers in materials has attracted serious attention from researchers and has become a new research trend. Such material structures are usually termed "smart" or more recently "nervous". Materials can have the capability of sensing and responding to the surrounding environmental stimulus, in the former, and the capability of feeling multiple structural and external stimuli, while feeding information back to a controller for appropriate real-time action, in the latter. In this paper, embeddable fibers, embedding processes, and behavior of fiber-embedded metallic materials are reviewed. Particular emphasis has been given to embedding fiber Bragg grating (FBG) array sensors and piezo wires, because of their high potential to be used in nervous materials for structural health monitoring. Ultrasonic consolidation and laser-based layered manufacturing processes are discussed in detail because of their high potential to integrate fibers without disruption. In addition, current challenges associated with embedding fibers in metallic materials are highlighted and recommendations for future research work are set.
纤维在材料中的嵌入已引起研究人员的高度关注，并成为一种新的研究趋势。这种材料结构通常被称为“智能”或最近的“神经”结构。在前一种情况下，材料能够感知并响应周围环境刺激；在后一种情况下，材料能够感知多种结构和外部刺激，同时将信息反馈给控制器以便进行适当的实时动作。本文综述了可嵌入纤维、嵌入工艺以及纤维嵌入金属材料的行为。由于光纤布拉格光栅（FBG）阵列传感器和压电导线在用于结构健康监测的神经材料中有很高的应用潜力，因此对其进行了特别强调。由于超声固结和基于激光的分层制造工艺在不破坏纤维的情况下集成纤维具有很高的潜力，因此对其进行了详细讨论。此外，还强调了目前在金属材料中嵌入纤维所面临的挑战，并提出了未来研究工作的建议。
