Microscopic damage such as matrix crack, interlaminar fracture and interfacial debonding generates within carbon fiber reinforced polymers (CFRPs) and causes reduction in mechanical properties of CFRPs. Inspired by biological system, a concept of self-healing was proposed. Self-healing composites are designed to sense damage and repair automatically, thereby improving the reliability of CFRPs. Self-healing is accomplished by containers incorporating healing agents within matrix of CFRP, thus it is important to distribute containers throughout the matrix to obtain sufficient self-healing efficiency. In this paper, we present simply outline of self-healing CFRPs and report recently progress for self-healing spread carbon fiber (SCF)/ epoxy (EP) laminates.
