Special Issue Information

Dear Colleagues,

Self-repairing composite materials are a class of new emerging materials having the ability to heal/repair themselves by mimicking the self-healing functionality that is observed in many living organisms. In comparison to traditional materials, self-repairing materials display the extraordinary ability of self-repair when subjected to failure through fracture/fatigue. Self-repairing composite materials with imperative self-repairing effects are expected to result in the incorporation of a number of merits, as well as in resolving the traditional problems of polymers and their respective composite materials. In order to be considered as a self-repairing material, it must have certain properties, such as the ability to automatically repair materials; ability to repair damage to materials multiple times; ability to heal materials with defects of any size; reduced maintenance costs; exhibit better or equal performance in comparison to traditional materials and should be more economic compared to presently-used materials

This Special Issue of the Journal of Composites Science invites innovative contributions in terms of research articles, reviews, communications, and letters from around the globe. Potential topics include, but are not limited to, structure and chemistry of self-repairing composites materials; processing; properties, characterization; functionalization; and applications ranging from automotive to aerospace.

Concrete has the ability to naturally heal its cracks, in a process called self-healing. This article aimed to analyze the self-healing of concretes, evaluating the influence of fly ash and the age of occurrence of cracks. Concrete specimens were submitted to cracking at 7 and 28 days. Subsequently, the samples were exposed to 12 wetting and drying cycles in order to favor the self-healing process. The phenomenon was evaluated through the ultrasonic pulse velocity testing, performed weekly on the specimens from the molding stage until the end of all cycles. The concretes showed a decrease in ultrasonic pulse velocity at the time they were cracked. This is due to the greater difficulty in the propagation of ultrasonic waves in the voids formed during cracking. This drop was higher for concrete with fly ash. Also, the results show that the fly ash concretes presented a more expressive self-healing process when cracked at 28 days, which may be related to the presence of pozzolanic reactions and the presence of more anhydrous particles. The concretes without fly ash had self-healing when they were cracked at 7 days. This is explained by the high hydration rate characteristic of ordinary Portland cement. Full article
