For instance, some require heating in an oven, which can&#8217;t be done for large components or while a given part is in use.&#8221; <\/p>\n<p>&#8220;Second, the self-healing only works for a limited period. For example, the material might be able to heal a few times, after which its self-repairing properties would significantly diminish. We&#8217;ve come up with an <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>roach that addresses both of those challenges in a meaningful way, while retaining the strength and other performance characteristics of structural fiber-composites.&#8221;<\/p>\n<p>In practical terms, this means users can rely on a given structural component, such as a wind-turbine blade, for a much longer period of time without worrying about failure.<\/p>\n<p>&#8220;By increasing the longevity of these composites, we make them more sustainable,&#8221; Patrick says. &#8220;And while wind-turbine blades are a good example, structural composites are found in a wide variety of applications: aircraft wings, satellites, automotive components, sporting goods, you name it.&#8221;<\/p>\n<p>Here&#8217;s how the new, self-healing fiber-reinforced composite works.<\/p>\n<p>Laminated composites are made from layers of fibrous reinforcement, e.g. glass and carbon-fiber, bonded together. Damage most often occurs when the &#8220;glue&#8221; that binds these layers together begins to peel away from the reinforcement, or delaminate. <\/p>\n<p>The research team addressed this problem by 3D printing a pattern of thermoplastic healing agent onto the reinforcement material. The researchers also embedded thin &#8220;heater&#8221; layers in the composite. When an electrical current is applied, the heater layers warm up. This, in turn, melts the healing agent, which flows into any cracks or microfractures within the composite and repairs them.<\/p>\n<p>&#8220;We&#8217;ve found that this process can be repeated at least 100 times while maintaining the effectiveness of the self-healing,&#8221; Patrick says. &#8220;We don&#8217;t know what the upper limit is, if there is one.&#8221;<\/p>\n<p>The printed thermoplastic also enhances inherent resistance to fracture by up to 500%, meaning it requires more energy to cause delamination in the first place. In addition, the healing agent and heater layers are all made of readily available materials, and are relatively inexpensive.<\/p>\n<p>&#8220;While making composites that incorporate our design would be marginally more expensive, the cost would be more than offset by significantly extending the lifespan of the material,&#8221; Patrick says.<\/p>\n<p>Another advantage of the new technology is that, if incorporated into aircraft wings, the internal heating elements would allow airlines to stop using chemical agents to remove ice from wings when aircraft are on the ground, and also to de-ice in flight.<\/p>\n<p>&#8220;We&#8217;ve demonstrated that this multi-functional technology works,&#8221; Patrick says. &#8220;We&#8217;re now looking for government and industry partners to help us tailor these polymer-based composites for use in specific applications.&#8221;<\/p>\n<p>The paper is published in <i>Nature Communications<\/i>.\n                                                                                                                        <\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            <a rel=\"nofollow noopener\" target=\"_blank\" class=\"text-medium text-info mt-2 d-inline-block\" href=\"https:\/\/phys.org\/news\/2016-09-composites-self-heal-temperatures.html\">Researchers find way of developing composites that self-heal at very low temperatures<\/a>\n                                        <\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Alexander D.
