With their high specific modulus, high specific strength and designability, fiber-reinforced polymer (FRP) composites have replaced or surpassed traditional metallic materials in a wide range of applications. However, the polymer matrix of commonly used FRP composites is usually a thermosetting polymer that is difficult to rework once formed, which implants a substantial challenge for the repair and recycling of composites. Self-repair, as an emerging method of repairing polymer-based materials, has the advantages of simplification, high efficiency and repeatability against traditional repair methods. Research on self-healing polymer materials is developing rapidly and becoming more systematic. With the development of self-healing polymer, polymer-based composites with self-healing capabilities are becoming possible. This paper reviews the current development of self-healing polymers in recent years, with specific emphasis on their applications in FRP composites. According to the difference in healing mechanisms, the self-healing polymer composites are split into two categories, intrinsic and extrinsic ones. The essential concepts and different types of intrinsic and extrinsic self-healing composites are first introduced. Then, their pros and cons are discussed, respectively. Finally, the perspectives of intrinsic as well as extrinsic self-healing FRP composites are put forward.

内在和外在自修复纤维增强聚合物复合材料：综述
纤维增强聚合物（FRP）复合材料以其高比模量、高比强度和可设计性，在广泛的应用中取代或超越了传统金属材料。然而，常用的FRP复合材料的聚合物基体通常是热固性聚合物，一旦成型就很难再加工，这给复合材料的修复和回收带来了巨大的挑战。自修复作为一种新兴的高分子材料修复方法，相对于传统修复方法具有简单、高效、可重复等优点。自修复高分子材料的研究正在迅速发展并日趋系统化。随着自修复聚合物的发展，具有自修复能力的聚合物基复合材料正在成为可能。本文综述了近年来自修复聚合物的发展现状，重点介绍了其在FRP复合材料中的应用。根据修复机制的不同，自修复聚合物复合材料分为内源性和外源性两类。首先介绍了内在和外在自愈复合材料的基本概念和不同类型。然后分别讨论它们的优缺点。最后，提出了内在和外在自修复FRP复合材料的观点。首先介绍了内在和外在自愈复合材料的基本概念和不同类型。然后分别讨论它们的优缺点。最后，提出了内在和外在自修复FRP复合材料的观点。首先介绍了内在和外在自愈复合材料的基本概念和不同类型。然后分别讨论它们的优缺点。最后，提出了内在和外在自修复FRP复合材料的观点。
