Glass fibers are useful because of their high ratio of surface area to weight. However, the increased surface makes them much more susceptible to chemical attack. Glass strengths are usually tested and reported of "virgin" fibers which have just been manufactured. The freshest, thinnest fibers are the strongest and this is thought to be due to the fact that it is easier for thinner fibers to bend. The more the surface is scratched, the less the tenacity is (Volf, 351). Because glass has an amorphous structure, its properties are the s ...

The basis of textile grade glass fibers is silica, SiO2. In its pure form it exists as a polymer, (SiO2)n. It has no true melting point but softens up to 2000°C, where it starts to degrade. At 1713°C, most of the molecules can move about freely. If the glass is then cooled quickly, they will be unable to form an ordered structure (Gupta, 544). In the polymer it forms SiO4 4- groups which are arranged as a tetrahedron with the silicon atom at the center and four oxygen atoms at the corners. These atoms then form a network bonded at ...

There are two main types of glass fiber manufacture and two main types of glass fiber product. First, fiber is made either from a direct melt process or a marble remelt process. Both start with the raw materials in solid form. They are mixed together and melted in a furnace. Then, for the marble process, the molten material is sheared and rolled into marbles which are cooled and packaged. The marbles are then taken to the manufacturing facility where they are inserted into a can and remelted. Then the molten glass goes to the bushing to be formed into fiber. In the direct melt process, the molten glass in the furnace ...

A plug or buck is required first to make a mold. This will be an orginal part that is to be copied. First the plug must be waxed with mold release wax. Depending on the desired surface, PVA (Poly Vinyl Acetate) may be sprayed on as an additional mold release agent. However this will reduce the smoothness of the molds finish. Once the plug has its release agent applied, gel-coat is sprayed onto the plug. Gel-coat is a pigmented resin without reinforcement. Tooling ...

Fiberglass is the most common residential insulating material, and is usually applied as batts of insulation, pressed between studs. Use personal protective equipment when you install fiberglass, such as mask, goggles, gloves, pants tucked into socks, and long-sleeved shirt, to protect yourself from the airborne fibers. Don’t use a 50-cent dust mask. Use a mask OSHA-certified to guard against airborne glass fibers. Some people believe that airborne glass fibers can cause cancer, and that fiberglass, on a per-fiber basis, is almost as dangerous as ...

Insulation is any material used to reduce or “slow down” or “resist” the flow of energy. There are several different types of insulators: Thermal insulators reduce the flow of heat. Electrical insulators reduce the flow of electricity. Acoustical insulators reduce the flow of sound. A material may insulate well in more than one way. Some materials, such as diamond, are superb insulators in one way (electrical), but extremely poor insulators in another way (thermal). Purified synthet ...

The word chop can refer to: A cut of meat, (specifically pork, lamb or mutton) that contains a bone, usually a rib. Chops are normally cooked by grilling, although barbecuing and baking are also common. A form of fiberglass consisting of short 6-8 inch lengths of glass that is shot out of a pneumatic gun with resin in to a mold. This method is used often when one side of the finished product is not seen, or when large quantities of a product must be made cheaply and quickly without regards to strength. ...

The materials definition of a glass is a uniform amorphous solid material, usually produced when a suitably viscous molten material cools very rapidly to below its glass transition temperature, thereby not giving enough time for a regular crystal lattice to form. A simple example is when table sugar is melted and cooled rapidly by dumping the liquid sugar onto a cold surface. The resulting solid is amorphous, not crystalline like the sugar was originally, w ...

An air filter is a device which removes contaminants, often solid particles such as dust, pollen, mold, and bacteria from air. They are often used in internal combustion engines, gas compressors, diving air compressors, ventilation systems, and any other application where air quality is important. Engine intakes tend to use either paper, foam, or cotton filters. Some buildings, as well as planes and other man-made environments (e.g., satellites and space shuttles) use foam, pleated paper, or spun fiberglass filter elemen ...

Whitewater kayaking is the sport of paddling a kayak on a moving body of water, typically a river. Whitewater kayaking can range from a fun, carefree, splishy-splash float trip to a challenging, adrenaline filled sport. The kayak (or just 'boat') used in whitewater kayaking is different than those used in Whitewater Racing or Sea Kayaking. Traditionally, kayaks were made of animal skins stretched over wooden frames. Early whitewater boats were fiberglass or kevlar. Today boats are typically made of a tough plastic that is sligh ...

A conga is a tall narrow single-headed Cuban drum (of African origin, derived from the Congolese Makuta drums). It was initially made from hollowed logs with cowhides nailed or strung on, and used by religious groups. The name "conga" was coined in New York, USA in the 1950's, when Cuban Son music and New York jazz fused together to create salsa. In its current incarnation, it has a fiberglass or wooden shell and a screw-tensioned drumhead. They are usually played in sets of two to four with the fingers and palms of the ...

A crop, sometimes called a riding crop or hunting crop, is a rather short type of whip without a crack, used in horseback riding, hence also known as a horsewhip. A crop usually consists of a long rod of fiberglass or cane or which is covered in leather, fabric, or similar material. The rod of a crop thickens at one end to form a handle, and terminates in a thin, flexible tress such as wound cord or a leather tongue. The thin end is intended to make contact with the horse. The han ...

A wide variety of substances can serve as insulators. For example, an insulator can be organic, inorganic, fibrous, cellular, reflective, rigid, soft, or granular. Most organic insulators are made from petrochemicals and recycled plastic. Most inorganic insulators are made from recycled materials such as glass and furnace slag. A new home might use half a dozen different insulating materials in different parts of the house. Each type ...

Insulate all ducts and water supply pipes where they pass through unconditioned spaces, such as through an attic or crawlspace that is not heated or air-conditioned. This includes heating, ventilation, air-conditioning, and return ducts, and both cold and hot water supply pipes. Before insulating ducts and pipes: Cement duct joints. Check the ductwork for leaks, and repair any that you find. Do not use duct tape - it is not designed for permanent appl ...
