Vascular Networks Make Self-healing Possible in Composites | Biomimicry | Scoop.it

"One of the more intriguing capabilities in nature is, however, the number of biological systems that are able to self heal. Scientists, spurred on by the potential economic benefits of materials that would be able to repair themselves  - longer lifetime, lower maintenance costs and more efficiency - have worked to develop self-healing systems for various materials, including plastics. And with success: various polymers are now available which have  the intrinsic ability to repair damage caused by usage over time. Up until now, however, composites, were a whole different ballgame. But once again, nature showed the way."
