COMPOSITE MATERIALS IN AVIATION

Introduction

Currently in the aviation industry it is necessary to implement new technologies in terms of materials for the construction of modern aircraft and this makes large companies such as Boeing and Airbus need for new materials that enable them to build airplanes with materials they can assure them that their model airplanes are better every day, that makes today you implement materials industry aircraft compounds that enable them to improve their models.

In the aviation industry with and aso the years we can evidence that have replaced many heavy materials that prevented them loa aircraft on long journeys today with the implementation of composite materials aircraft become more efficient, lighter and that is reflected in the production costs are reduced and improve the mechanical condition of the aircraft.

Among the new composite material technologies that are deployed today in aircraft found the following composite materials:

Fiberglass

Since it is the material of Joint Compound Plus, fiberglass, made from glass fibers embedded in a resin matrix, was used first in Great Measure for ships and automobiles in the 1950s, said the Centennial Commission Flight. It used also was during this time in the construction of the Boeing 707 Passenger. In 2010, engineers still use fiberglass in aircraft construction, for example in the construction of airplane wings.

Carbon Fiber

This compound, Made of carbon atoms and an epoxy matrix, has great value because lighter weight do. According to "carbon fiber composites (carbon fiber composites)," the US space shuttle SE USING carbon fiber. "Fundamentals of Composites Manufacturing (The bottom About Compounds for manufacturing)" says ,: In addition, the this material provides high cost performance m, launching into space costing around US $ 10,000 per pound each (0.45 kg) from the year 2008. Carbon fiber also provides heat resistance and is therefore useful for spacecraft and military aircraft.

Boron fiber

Composite Materials Fiber boron, according to "composite materials for aircraft structures (Composite Materials for Aircraft Structures)" Were first discovered in 1959 and developed later in the material of the United Nations High Performance . During the 1970s, it Was used in the construction of the Military Aircraft F-14 and F-15.

Given its large diameter (100 to 140 micrometers), boron fiber has a high bending stiffness limiting its use a contradictory Smaller Aircraft More complex. Feature esta distingué of carbon fiber, the diameter Smaller provides a flexibility mayor.

Titanium Aluminum

The titanium aluminum alloy differs from the UN compound, But Search Results equally valuable as the material of the United Nations aerospace construction. Mechanical engineer Kenneth Vecchio Formed materials This is the year 2005, after studying the natural design of the abalone shell, which has a tremendous construction.

 Aluminum alloy titanium is an option UN lightweight, As steel in construction aviation / aerospace says "Environmental Engineering (Environmental Engineering Environment)".

Conclusion

We can see that now in the aviation industry and virtually most of the materials used to manufacture aircraft are mostly composite carbon fiber being the most used mainly in the size of the plane's wings . Significantly, the composites came with great force to stay as great leaders in the construction of aircraft by representing the big smaller manufacturers costs when making an aircraft and composite materials generate them greater reliability in each of its models .
