Using carbon fibres in airliners is a smart move because it's both lightweight and strong. The use of composites also helps to reduce the weight of the aircraft and therefore reduces the amount of fuel required for flight. The cost of flying increases with the weight of the aircraft, so it's worth considering how much the weight can be reduced.
Carbon fibres have the potential to reduce the weight of an aircraft by as much as 20%. Its high strength to weight ratio and ability to be produced in a variety of shapes means that it has a number of uses in the aerospace industry. Carbon fibres are also used for construction in boats, bicycles, and automobiles.
Although carbon fibres are very thin, they can be made strong by heat treatment. Depending on the type of fiber, it can be produced with a range of tensile, compressive, and fatigue strengths. Carbon heated at 1500-2000 degC produces the highest tensile strength while carbon heated at 2500-3000 degC produces the highest elasticity.
Aerospace is a huge user of carbon fiber. For example, Boeing 787 Dreamliner uses composites for half of its airframe. The use of composites in airliners has been commonplace since the mid-70s. The latest planes are designed around lightweight carbon fibre composites. In fact, they have become the material of choice for many aircraft designers.
High-performance carbon fibres were first produced in 1958 by Roger Bacon. Using a heat-treatment process, the fibers were produced from a raw material called polyacrylonitrile, or PAN. This is a type of composite that can be manufactured with a very low cost. A PAN-based carbon fiber, however, has a very low tensile strength and a relatively low modulus of elasticity. Fortunately, this does not have to be the case.
In addition to having the best strength-to-weight ratio, carbon fibers are very thin and are therefore very light. This means that the aerodynamics of a composite air wing are likely to be very different from that of a metal wing.
One of the benefits of using a carbon fibre wing is that it can save you up to 5% in fuel consumption. It's also possible to use a hybrid carbon fibre that combines graphitic and turbostratic materials. However, because there are many different carbon fibre products on the market, it's important to understand which is best for your specific application.
A lot of research has gone into developing new materials for aircraft. In particular, the National Composites Centre has been developing materials and new designs for aircraft. It's recently teamed up with European aircraft manufacturer Airbus to develop the trailing edge of the wing on its latest aircraft. This has helped to improve the lift-to-drag ratio.
One of the most important factors in developing the best aircraft is weight. A lighter aircraft can save up to $1 million over the lifetime of the aircraft. It's also important to understand trade-offs during the design process. This is especially true in airliners, as weight is an important consideration.
