An Investigation on Manufacturing of Self-healing Materials

Abstract

Self-healing material is receiving an increasing amount of worldwide interest as a method to autonomously address damage in materials. Biological organisms have an amazing ability to automatically initiate self-healing. Materials engineers are dreaming about making materials that could replicate the same features. Self-healing materials are a class of smart materials that have the ability to incorporate repairing ofstructural damage caused by mechanical usage over time. Initiation of cracks and other types of damage on a microscopic level has been found to change thermal, electrical, and acoustical properties, and eventually lead to whole scale failure of the material. The reason of failure usually, found in the form of cracks, are sorted out by special instrumentsand are mended by hand, which is unsatisfactory because cracks often needs cautious work to detect& repair them. A material (polymers, ceramics, etc.) that can intrinsically correct damage caused by normal usage could lower production costs of a number of different industrial processes through longer part lifetime, reduction of inefficiency over time caused by degradation, as well as prevent costs incurred by material failure is discussed in this paper. Imagine self-repairing cars, planes, bridges or buildings. These materials could be of particular use in structures that are at present impractical or impossible to repair, such as electronic circuit boards, implanted medical devices or spacecraft. Self-repairing materials would have a massive impact on virtually all industries, lengthening product lifetimes, increasing safety, and lowering product costs by reducing maintenance requirements.
