Other types of airplane Introduction Composite materials arewidely used in the Aircraft Industry and have allowed engineers to overcomeobstacles. To be able to built a lighter, better and faster airplanes, in somecases like the military it can provide better aerodynamic performance. Example: Military airplane:Eurofighter TyphoonCommercial airplane:Boeing 787Glider: SparrowHawk -Eurofighter Typhoon:Strong, lightweightcomposite materials were key to the designof Eurofighter Typhoon, which provides greater tensile strength and moreaerodynamic performance with less weight and more reliability than traditionalmaterials. -Boeing 787:Boeing 787 makes greateruse of composite materials in its airframe and primary structure.
airframe comprisingnearly half carbon fibre reinforced plastic and other composites.composites, especiallyin the highly tension-loaded environment of the fuselage, greatlyreduces maintenance due to fatigue when compared with an aluminumstructure. -SparrowHawk:The vast majority ofsailplanes (also called gliders) across all categories have been fabricatedfrom a wet layup of fibreglass/epoxy.
The SparrowHawk is the first sailplanewith all-carbon composite wings and fuselage.How the parts are made-Eurofighter Typhoon: EuroFighter typhoon is made with 70% Glass Fibre composite for boosting range and performance as well as reducing the radar signature. By using composite the airplane weight 30% lesser than traditional materials. Glass Reinforced Plastic (GRP) for the plane nose and at the end of the plane’s tail.
-Boeing 787: Has an airframe comprising of nearly half carbon fibre reinforced plastic and other composites (50% of the plane). The other 50% is used by metal or others. Which means that lower the overall airplane weight, and by moving to a composite primary structure which means it reduce both the scheduled and nonroutine maintenance burden on the airlines.-SparrowHawk: The whole frame are made up of prepreg which ensure more consistent fibre volume and cleaner overlaps than wet layup would offer. Parts are bonded with certain adhesives. Bond gaps are minimized to keep strength up and adhesive weight low.
What it is made of?-Eurofighter Typhoon: Carbon Fibre Composites- 70% ( Frame of the airplane) Metal- 15% ( For the wings ) Glass Reinforced Plastic (GRP)- 12% ( The nose and tail of the plane) Other Material- 3% (Others) -Boeing 787: Carbon Fibre Reinforced and other Composites- 50% ( Frame of the plane) Aluminium- 20% ( Strengthening the tail of the plane) Titanium- 15% ( Tail and part of the engine) Steel- 10% ( Mainly for the landing gear) Others- 5% ( Tail, case of the engine, tip of the wings and others)-SparrowHawk: Carbon Fibre Composite- Entire structure is made of Carbon/Epoxy Composite Combinations ofcomposites materials used-Eurofighter Typhoon: Carbon Fibre Composites Glass Reinforced Plastic -Boeing 787: Carbon Fibre Reinforced and other Composites -SparrowHawk: Carbon Fibre Composite List of materials usedin the production of the parts.-Eurofighter Typhoon: Carbon Fibre Composites Glass Reinforced Plastic -Boeing 787: Carbon Fibre Reinforced and other Composites -SparrowHawk: Carbon Fibre Composite (Prepreg and adhesive) What are the advantagesand the disadvantages of use of composite material in aerospace industry? Advantages: Weight reduction is the single greatest advantage of composite material usage and is the key factor in using it in aircraft structure. Fibre-reinforced matrix systems are stronger than traditional aluminum found on most aircraft, and they provide a smooth surface and increase fuel efficiency, which is a huge benefit.
Disadvantages: The resin used in composite material weakens at temperatures as low as 150 degrees, making it important for these aircraft to take extra precautions to avoid fires. composite materials can be expensive Fires involved with composite materials can release toxic fumes and micro-particles into the air, causing health risks Temperatures above 300 degrees can cause structural failure. Repairs can be much more difficult when a composite surface is damaged, which ultimately becomes costly. Composite materials don’t break easily, that makes it hard to tell if the interior structure has been damaged at all. Composites are not as efficient in dealing with compression loads.
