Glass Cloth
Glass cloth is a textile material woven from fiberglass yarn. Home and garden Glass cloth was originally developed to be used in greenhouse paneling, allowing sunlight's ultraviolet rays to be filtered out, while still allowing visible light through to plants. Glass cloth is also a term for a type of tea towel suited for polishing glass. The cloth is usually woven with the plain weave, and may be patterned in various ways, though checked cloths are the most common. The original cloth was made from linen, but a large quantity is made with cotton warp and tow weft, and in some cases they are composed entirely of cotton. Short fibres of the cheaper kind are easily detached from the cloth. In the Southern Plains during the Dust Bowl, states' health officials recommended attaching translucent glass cloth to the inside frames of windows to help in keeping the dust out of buildings, although people also used paperboard, canvas or blankets. Eyewitness accounts indicate they were not c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Composite Materials
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical engineered composite materials include: * Reinforced concrete and masonry * Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass * Ceramic matrix composites ( composite ceramic and metal matrices) * Metal matrix composites *and other advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiberglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linens
Linens are fabric household goods intended for daily use, such as bedding, tablecloths, and towels. "Linens" may also refer to church linens, meaning the altar cloths used in church. History The earliest known household linens were made from thin yarn spun from flax fibres to make linen cloth. Ancient Egypt, Babylon, and Phoenicia all cultivated flax crops. The earliest surviving fragments of linen cloth have been found in Egyptian tombs and date to 4000 BCE. Flax fibres have been found in cloth fragments in Europe that date to the Neolithic prehistoric age. Cotton is another popular fibre for making cloth used for household linens. Its use in cloth-making also dates back to prehistoric times, in Indian subcontinent, China, Peru and Egypt. The Indian subcontinent was especially well known for high quality cotton cloth as early as 1500 BCE. Linen was an especially popular cloth during the Middle Ages in Europe, when cotton was an exotic import. It was used for undercloth ...

Woven Fabrics
Woven fabric is any textile formed by weaving. Woven fabrics are often created on a loom, and made of many threads woven on a warp and a weft. Technically, a woven fabric is any fabric made by interlacing two or more threads at right angles to one another. Woven fabrics can be made of both natural and synthetic fibres, and are often made from a mixture of both. E.g. 100% Cotton or 80% Cotton & 20% polyester. 60% spandex and 40% cotton could also be woven together. Woven fabric is typically used in clothing, garments, for decoration, furniture or covering purposes such as carpets. In the Midwest, it is popular to have woven wicker furniture in sitting areas such as a patio or a dining room. Qualities Woven fabrics only stretch diagonally on the bias directions (between the warp and weft directions), unless the threads used are elastic. Woven fabric cloth usually frays at the edges, unless techniques are used to counter it, such as the use of pinking shears or hemming. Different c ...

Glass Fiber
Glass fiber ( or glass fibre) is a material consisting of numerous extremely fine fibers of glass. Glassmakers throughout history have experimented with glass fibers, but mass manufacture of glass fiber was only made possible with the invention of finer machine tooling. In 1893, Edward Drummond Libbey exhibited a dress at the World's Columbian Exposition incorporating glass fibers with the diameter and texture of silk fibers. Glass fibers can also occur naturally, as Pele's hair. Glass wool, which is one product called "fiberglass" today, was invented some time between 1932 to 1933 by Games Slayter of Owens-Illinois, as a material to be used as thermal building insulation. It is marketed under the trade name Fiberglas, which has become a genericized trademark. Glass fiber when used as a thermal insulating material is specially manufactured with a bonding agent to trap many small air cells, resulting in the characteristically air-filled low-density "glass wool" family of produ ...

G-10 (material)
G-10 or garolite is a high-pressure fiberglass laminate, a type of composite material. It is created by stacking multiple layers of glass cloth, soaked in epoxy resin, then compressing the resulting material under heat until the epoxy cures. It is manufactured in flat sheets, most often a few millimeters thick. G-10 is very similar to Micarta and carbon fiber laminates, except that glass cloth is used as filler material. (Note that the professional nomenclature of "filler" and "matrix" in composite materials may be somewhat counterintuitive when applied to soaking textiles with resin.) G-10 is the toughest of the glass fiber resin laminates and therefore the most commonly used. Properties G-10 is favored for its high strength, low moisture absorption, and high level of electrical insulation and chemical resistance. These properties are maintained not only at room temperature but also under humid or moist conditions. It was first used as a substrate for printed circuit b ...

Pre-preg
Pre-preg is a composite material made from "pre-impregnated" fibers and a ''partially cured'' polymer matrix, such as epoxy or phenolic resin, or even thermoplastic mixed with liquid rubbers or resins. The fibers often take the form of a weave and the matrix is used to bond them together and to other components during manufacture. The thermoset matrix is only partially cured to allow easy handling; this B-Stage material requires cold storage to prevent complete curing. B-Stage pre-preg is always stored in cooled areas since heat accelerates complete polymerization. Hence, composite structures built of pre-pregs will mostly require an oven or autoclave to cure. The main idea behind a pre-preg material is the use of anisotropic mechanical properties along the fibers, while the polymer matrix provides filling properties, keeping the fibers in a single system. Pre-preg allows one to impregnate the fibers on a flat workable surface, or rather in an industrial process, and then lat ...

Rutan VariEze
The Rutan VariEze is a composite, canard aircraft designed by Burt Rutan. It is a high-performance homebuilt aircraft, hundreds of which have been constructed. The design later evolved into the Long-EZ and other, larger cabin canard aircraft. The VariEze is notable for popularizing the canard configuration and moldless glass cloth composite construction for homebuilt aircraft. Overview Work on the VariEze design, which grew out of Rutan's experience designing and building the VariViggen, began in 1974. The first prototype, designated Model 31 and registered N7EZ, first flew on May 21, 1975 after four months of construction. This aircraft used a Volkswagen engine conversion. Three months later it was shown at Oshkosh where Dick Rutan piloted it to an under 500 kg class distance record of . Rutan believed that by engaging in a program of breaking class records he could further fine-tune the design. The aircraft was so popular at Oshkosh that Rutan redesigned the ai ...

Dust Bowl
The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. The phenomenon was caused by a combination of both natural factors (severe drought) and manmade factors (a failure to apply dryland farming methods to prevent wind erosion, most notably the destruction of the natural topsoil by settlers in the region). The drought came in three waves: 1934, 1936, and 1939–1940, but some regions of the High Plains experienced drought conditions for as many as eight years. The Dust Bowl has been the subject of many cultural works, notably the novel ''The Grapes of Wrath'' (1939) by John Steinbeck, the folk music of Woody Guthrie, and photographs depicting the conditions of migrants by Dorothea Lange, particularly the '' Migrant Mother'', taken in 1936. Geographic characteristics and early history With insufficient understanding of the ecology of the plains, farmers had conducted extensiv ...
