This review is a denote to the detailed analysis of the self-healable features of Carbon Fiber-Reinforced Polymer (CFRP) composites. It discusses the different healing strategies, types of employed healers, time to healing, mechanical recovery, inherent properties such as glass transition temperature, and the advantages and disadvantages of each healing strategy. Composite materials with self-healing capabilities can automatically repair themselves after being degraded. As a result, maintenance tasks are greatly simplified. This paper aims to give a concise overview of the most recent advancements in self-healing composites. The article complements earlier survey papers by offering an updated overview of the many self-healing theories over the preceding two decades and a comparison of healing processes and manufacturing methods for creating micro-capsules and microvascular networks. The review also dispenses a summary of diverse chemistries utilized to fabricate self-healable polymeric composites and their future scope to humankind. To identify significant challenges and prospective research insight, elements that affect healing efficiency are provided based on the research assessment. This provides a basis for the researchers for future applications based on these intelligent self-healing composites.
