Carbon fiber construction against tornadoes

The tornado struck this week in the city of Joplin, Missouri, causing heavy casualties and causing massive home collapses. These collapsed houses are made of wood, steel and concrete, and the construction technology has been around for 100 years. Scientists believe that houses built with materials such as carbon fiber, concrete cloth, and Kevlar will be stronger enough to withstand extreme weather, including tornadoes.

Kevlar, steel wire mesh and carbon fiber all have the flexibility that traditional materials such as wood and concrete cannot match. Houses made from these materials have a much lower chance of collapsing than many very solid houses nowadays. According to the American Fun Science website on May 24th, Bradley Quinn, the author of the new book Designing the Future, which mainly introduces advanced materials, said that there is a new type of architecture that is working harder to design and adapt to nature. It is not a construction that is opposed to nature.

Carbon fiber has long been used to make small items such as bicycles or eyeglasses. In fact, carbon fiber can also be "incarnate" into tough building materials to make a strong and durable house. Quinn said that carbon fiber has incredible rigidity and flexibility, can withstand earthquakes, and can withstand the "test" of a tornado more than traditional structures.

Widely used in the material of the ** vest Kevlar developed by the United States DuPont company in the 1960s, with low density, high strength, good toughness, high temperature resistance, easy processing and molding and so on. Kevlar material can keep people and houses away from the debris that has been caught during a tornado attack and acts as an “umbrella” for the affected people. Quine said that now scientists have used Kevlar materials developed by DuPont to build a "Dupont Storm House" that looks like a tent made of wire mesh and Kevlar material that can be Stand upright from the inside, keeping people away from all debris that is scattered around.

However, using future materials such as carbon fiber and Kevlar and new architectural concepts, the cost of building a house can be very high. Now, for many affected people in the city of Joplin in the United States, houses built with concrete cloth can better alleviate the urgency.

Concrete cloth is a special kind of impregnated fiber. When water is added to it, it can become a spine-like bulge. Therefore, concrete cloth can be used to construct a reinforced protective shelter. The concrete fabric was originally designed to build military bases. Its working principle is the same as plaster bandages. When water is sprayed on it, a chemical reaction takes place. After drying a little, a very strong building structure will appear that can withstand any extreme climate. Quinn said that concrete fabrics are easy to manufacture, easy to handle, and cheap enough to be a "refuge" for those who are not affected by the storm.

Quinn said that the idea of ​​a more radical architecture school was even more bold. They designed a building called the “underground building” (as opposed to a skyscraper) that was built underground to prevent it from passing by a tornado. "Pool of fish."
