exam) There are two key reasons for using thermoplastic composites: * save time & handling costs in production * eliminate labour-intensive riveting & bonding * can produce large profile sections that are some 20 % lighter than metal & alloys. * materials are exceptionally stiff and can tolerate vibrations A380 (largest passenger plane) - 25 % of the structure & components are composites. And in the next generation of aircraft‚ the content of composites will double

United Metals has decided to launch the production of a new product‚ the firm is expecting this project to last over 8 years. The issue at hand is to know whether it would be more advantageous for United Metals to produce the components itself or to directly buy them from one of its suppliers‚ Amalgamated Components. In order to arbitrage between the “make” and “buy” decision we will calculate the Net Present Value of both these options. In order to do so we will first compute the annual cash flows

group called the alkaline earth metals. Magnesium is found in seawater‚ salty layers and in many rock minerals. IT could be used as metal. It’s the third most abundant structural metal in the earth’s crust‚ only exceeded in aluminum and iron.Magnesium readily ignites upon heating in air and burns with a dazzling white flame. To extinguish the flame water should not be used. Alkaline earth metal salts in general‚ are less soluble in water than the corresponding alkali metal salts. Some are even so insoluble

Chromium is a member of the heavy metal group of iron‚ lead‚ mercury‚ and arsenic. Chromium 6 as well as lead‚ mercury and arsenic are very toxic not only to cells but also on the body tissue. Chromium typically bears a charge of +3 or +6 which is a highly- oxidized state for a metallic element. According to the Agency for toxic Substance and Disease Registry ‚ chromium is used in 3 main industrial areas: metallurgy ( manufacture of different metals and metal materials)‚ refractory ( heat-resistant

Metals and alloys for nuclear energy There are two important ways in the making of nuclear energy: nuclear fission and nuclear fusion. Fusion and fission have a different working mechanisms‚ thus other materials are used. In a nuclear reactor fuel rods are bombarded with neutrons causing fission of the fuel. This way energy is released. With this energy water is heated to steam and with the use of heat exchangers and steam turbines electricity is generated. As fuel is usually uranium used‚ but also

Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic transition metal‚ it has historically been sometimes classified as a rare earth element‚ together with yttrium and the lanthanoids. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. Scandium is present in most of the deposits of rare earth and uranium compounds‚ but it is extracted from these ores in only a few mines worldwide. Because of the low availability

Introduction: Copper has played a vital role in past civilizations and continues to do so today due to its many properties as a metal. Although advantageous in today’s economy and also in human bodies‚ high concentrations of copper can prove toxic to our health and even pollutant to the environment. By altering the element through a number of chemical reactions including redox‚ metathesis‚ decomposition‚ and single replacement reactions‚ the cycle will be complete once solid copper is recovered.
