Aerospace materials are materials, frequently metal alloys, that have either been developed for, or have come to prominence through their use for aerospace purposes. These uses often require exceptional performance, strength or heat resistance, even at the cost of considerable expense in their production or machining.
Carbon nanotube reinforced polymer (CNRP) is several times stronger and tougher than typical CFRPs and is used in the Lockheed Martin F-35 Lightning II as a structural material for aircraft. [55] CNRP still uses carbon fiber as the primary reinforcement, [ 56 ] but the binding matrix is a carbon nanotube-filled epoxy.
Ready to use carbon fiber sheet in the factory before molding. During the 1960s, experimental work to find alternative raw materials led to the introduction of carbon fibers made from a petroleum pitch derived from oil processing. These fibers contained about 85% carbon and had excellent flexural strength.
A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials that are feedstock for future finished products. As feedstock, the term connotes these materials are bottleneck assets and are required to produce other products.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
The helicopter is a “utility tactical transport” aircraft — used for everything from air assault to relief operations — that the Army says it has relied on for every major operation around ...
The recycled aluminum alloys can be used in aircraft parts such as stiffeners and flaps, where a growth in fatigue stress and fracture toughness are not critical to the component’s integrity. [18] The alloys can also be used for non-aircraft applications, such as truck bodies, rivets, auto bumpers, and castings. [18]
Hindustan Aeronautics Limited (HAL) was formed on 1 October 1964 (the Registrar of Companies has a registration date of 16 August 1963) [13] when Hindustan Aircraft Limited joined the consortium formed in June by the IAF Aircraft Manufacturing Depot, Kanpur (at the time manufacturing HS748 under licence) and the group recently set up to ...
