A mechanical engineer from theUniversity of Houstonhas created a sprayable ice-shedding substance that is 100 times more powerful than existing ones. Boeing tested the new resilient coating material under erosive rain conditions at 385 mph, and it surpassed the most recent coating technology for aerospace.

The new “fracture-controlled material” is based on the idea that any external solid object must be forced away from a surface to be detached (such as ice from an airplane wing) and that this force will invariably cause cracks at the interface. These fractures or fissures spread until the object completely separates from the surface.
可以使用由机械工程库伦(Cullen)副教授Hadi Ghasemi创建的新颖想法来精确管理和加速分离。
We developed a new concept in which, through material design, you can significantly accelerate the crack formation and growth and easily remove external objects from the surface. This concept is implemented to develop materials that are highly durable, and ice does not attach to these materials。

Fracture-controlled surfaces provide a rich material platform to guide future innovation of materials with minimal adhesion while having very high durability。

A Necessary Solution
在1990年至2000年的天气造成的所有飞行灾难中,应归咎于12%。在电力部门,传输系统中的结冰会导致导体破裂,绝缘体闪存以及电线杆和塔楼的崩溃。
已经创建了各种具有冰上特性的材料来解亚博网站下载决结冰的问题。但是,许多人的耐用性相对有限,这限制了它们的有效性。
开发冰雪材料的主要挑战是找到具有低冰粘附和良好耐用性的材料亚博网站下载。
休斯顿大学机械工程库伦副教授Hadi Ghasemi
Ghasemi’s novel material offers both.
Developing new materials for aircraft, wind energy, and other industrial and commercial applications where ice is a problem is made possible by the new core idea of fracture-controlled materials. According to the researchers, ice formation on wind turbines might result in an 80% reduction in power generation, which these new coating materials could prevent.
