| Abstract |
When one cut himself, it's amazing to watch how quickly the body acts to mend the wound.
Immediately, the body works to pull the skin around the cut back together. The concept of repair by
bleeding of enclosed functional agents serves as the biomimetric inspiration of synthetic self repair
systems. Such synthetic self repair systems are based on advancement in polymeric materials; the
process of human thrombosis is the inspiration for the application of self healing fibres within the
composite materials. Preliminary results based on flexural 3 point bend test on prepared samples have
shown the healed hollow fibre laminate has a healed strength increase of 47.6% compared to the
damaged baseline laminate. These results gave us confidence that there is a great potential to adopt
such self healing mechanism on actual composite parts like in aircraft’s composite structures. |
