E-glass does not actually melt, but softens instead, the softening point being "the temperature at which a 0.55–0.77 mm diameter fiber 235 mm long, elongates under its own weight at 1 mm/min when suspended vertically and heated at the rate of 5 °C per minute". [11] The strain point is reached when the glass has a viscosity of 10 14.5 poise.
For kinematic viscosity, the SI unit is m^2/s. In engineering, the unit is usually Stoke or centiStoke, with 1 Stoke = 0.0001 m^2/s, and 1 centiStoke = 0.01 Stoke. For liquid, the dynamic viscosity is usually in the range of 0.001 to 1 Pascal-second, or 1 to 1000 centiPoise. The density is usually on the order of 1000 kg/m^3, i.e. that of water.
The material is provided in bulk or in logs approximately 4" in diameter. [2] [3] The glass fibers in BMC increase the strength properties of the product to be higher than standard thermoplastic products. The viscosity of BMC dictates how effectively it can fill a mold. When at high viscosity, the pressure applied to the BMC is not enough for ...
Rayon, also called viscose [1] and commercialised in some countries as sabra silk or cactus silk, [2] is a semi-synthetic fiber [3] made from natural sources of regenerated cellulose, such as wood and related agricultural products. [4] It has the same molecular structure as cellulose. Many types and grades of viscose fibers and films exist.

Optical fiber manufacturers have greatly refined their manufacturing process since that standard was issued and cables can be made that support 10 GbE up to 400 meters. Laser optimized multi-mode fiber (LOMMF) is designed for use with 850 nm VCSELs. Older FDDI grade, OM1, and OM2 fiber can be used for 10 Gigabit Ethernet through 10GBASE-LRM.
Lyocell is a semi-synthetic fiber used to make textiles for clothing and other purposes. [1] It is a form of regenerated cellulose made by dissolving pulp and dry jet-wet spinning. Unlike rayon made by the more common viscose processes, Lyocell production does not use carbon disulfide, [2] [3] which is toxic to workers and the environment.
[citation needed] For producing carbon fiber higher molecular weight is desired. [15] In the production of carbon fibers containing 600 tex (6k) PAN tow, the linear density of filaments is 0.12 tex and the filament diameter is 11.6 μm which produces a carbon fiber that has the filament strength of 417 kgf/mm2 and binder content of 38.6%.
