Researchers at the NC State University in the U.S. turned to 3D printing to add a healing layer to materials that will help equipment to heal onsite, aSelf-healing materials are the next frontier of technology that can help keep equipment in service for long periods of time. There has beenin use today still requires it to be removed from service for the healing process. At times, the healing process can require the use of a heating oven, which might not be conducive for use for large components.
Jason Patrick, an assistant professor of civil, construction, and environmental engineering at NCSU, and his team have now addressed these challenges by using additive manufacturing or 3D printing techniques to manufacture self-healing material.Most modern-day lightweight composite materials are made using layers of glass and carbon fiber that are held together using specialized glue.
Patrick and his team turned to 3D printing to put a pattern of a thermoplastic healing agent onto the laminated material. Embedded inside the laminated material were thin heater layers that could be turned on by supplying an electric current. The heat, thus generated, melts the healing agent that can flow into cracks or microfractures of the composite to repair them.
Interestingly, the research team found that the process could be repeated over 100 times, and the self-healing process was still effective.The research also found that the composite made using this technique was inherently resistant to fracture by as much as 500 percent. This meant that the material was less likely to get delaminated in the first place. Even when it did, the self-healing property of the material would allow it to remain in service for long periods of time.
By increasing the longevity of the equipment made using these composites, the researchers are making them more sustainable. This would apply to a range of equipment made from these composites ranging from wind turbines to automotive components, satellites, as well as sporting goods, the researchers said in the press release.
