Describe glass fibres fully.?

Fiberglass or fibreglass is material made from extremely fine fibers of glass. It is used as a reinforcing agent for many plastic products; the resulting composite material, properly known as glass-reinforced plastic (GRP) or glass-fiber reinforced epoxy (GRE), is called "fiberglass" in popular usage.\n\nGlass fiber is formed when thin strands of silica-based or other formulation glass is extruded into many fibers with small diameters suitable for textile processing. Glass is unlike other polymers in that, even as a fiber, it has little crystalline structure (see amorphous solid). The properties of the structure of glass in its softened stage are very much like its properties when spun into fiber. One definition of glass is "an inorganic substance in a condition which is continuous with, and analogous to the liquid state of that substance, but which, as a result of a reversible change in viscosity during cooling, has attained so high a degree of viscosity as to be for all practical purposes rigid."

fiberglass is glass the only possible chemical that could "disolve" (because it won't, it will create a salt) is hydrofluoric acid (HF). However this chemical is EXTREMELY DANGEROUS, it reacts with anything. Professional training is needed before handeling this chemical (lethal dose is 30 ppm)

Well, I work with glass for a living, and for me, two different types of glass are Moretti and Boroscilicate. Boro glass is commonly referred to as Pyrex; it has a higher melting temperature and, when annealed (cooled) properly, is very resistant to breaking. Moretti is a softer, soda-lime glass, with a lower melting temperature (this is the kind I typically work with.) in my sources i've put some links to some glass sellers who could tell you more about different types of glass.

1st -- tips of the hat to in-janier and lewis_brown for stopping by long enough to give the basic physics and most of all to Lewis for politely informing us that glass is not a liquid.  \n\nGlass is a liquid?  Pull-eeze!  How in the world do you come up with that one, people?  \n\nGlass "flows" -- ???  \n\nGlass flows in liquid state -- only.\n\nGlass is solid until melted.  Then and only then it's liquid.\n\nGlass melts at 2600-2900 °F (1425-1600 °C) depending on its composition.\n\nWhere on Earth do you think glass is liquid or flows at bench temperature?\n\nAnway, I originally stopped by just to ask the asker if he or she could see through black glass (or any other opaque glass)?

Fiberglass is threads of spun glass, used for insulation. It can give you a rash, and you shouldn't breathe it, but it's pretty safe.\n\nUnless you mean asbestos, which can look similar, and often causes a specialized form of cancer called mesothelioma.

I had an essay on optical fibers last semester and this link was really, really helpful:\n\nhttp://electronics.howstuffworks.com/fiber-optic.htm\n\nWikipedia's not so bad too:\nhttp://en.wikipedia.org/wiki/Fiber_optics

Fiber optics is made of silica. it transmots data at a more faster speed compared to other communiation media and it's also more secured because you can't tap into the network illegally. a single fibre cable can replace a bunch of copper cables. Data in fiber travels at the speed of light. it has two types, the single and the multi mode.

wikipedia comes to mind or do a Yahoo search. Put "plant anatomy" and "plant fiber" in quotes.

Fiberglass or fibreglass is material made from extremely fine fibers of glass. It is widely used in the manufacture of insulation and textiles.

There are a couple of different fibers being used.\n\nKevlar by DuPont, Spectra by Honeywell, Aramid by Aramid and various combinations of the fibers woven together to form hybrid weaves.

Glass is made of sandstone.  Stone would be earth.

Glass and SiO2 are chemically same. But the glass is sytematic arrangement of atomic structure and can happen as a slow physical process

Fiber Optics are Glass or Silica fibres which are used to transmit light from Point A to Point B.\nAnd can you clarify: "can u really put a camera using it?"\n\nPS: Fiber Optics are NOT Light Source but a Channel

Glass is more dimensionally stable - it doesn't expand or contract when the temperature changes - and it can be polished to a very smooth surface.   The finish is a very very thin layer of metal.\n\nRead "The Perfect Machine" by Ronald Florence if you want to learn more.
