DEVELOPMENT OF SELF HEALING COMPOSITE MATERIALS AND INNOVATIVE TECHNIQUES FOR STRUCTURAL HEALTH MONITORING ON AEROSPACE APPLICATIONS

Abstract: 

Self Healing Materials are a class of smart materials. It is an innovation of recent years, intended for application to advanced manufacturing technologies such as Aerospace-industry. The development and characterization of self-healing synthetic polymeric materials has been inspired by biological systems in which damage triggers an autonomic healing response. Thermally Remendable Polymers belong to this class of materials while the healing is activated after an application of a specific stimulus (e.g. heat).

In this project we will attempt to manufacture various types of Thermally Remendable Polymers that follows the Diels-Alder (DA) chemical reaction, in order to select the most suitable for the particular application. Alongside the rapid development of nanotechnology and the possibility of manufacturing a nano-scale materials has opened new horizons in materials science.

This proposed research project combines these two technologies in an attempt to exploit the distinct properties to develop an advanced polymer with upgraded intrinsic properties. The basic idea is to add in a Thermally Remendable polymer matrix nano-inclusions (ferromagnetic nanoparticles, carbon nanotubes, micro wires) obtaining magnetic and electrical properties. A very important aspect is that these properties are proved to be strain depended. So by this manner, it will be possible to identify areas of the material where possible structural failure may start, as microcacks, or even identify damaged areas containing cracks, holes etc. Also the nano-inclusions will act as a heating susceptor (for induction, microwave heating) which will generate and eventually transfer heat to the material in order to activate its self healing properties.

The final result that will emerge from this research will be an advanced material with self healing and strain sensing capabilities which could be repaired locally without having the need to replace it.
