Multiple issues orphan May 2011 unreferenced February 2011 wikify February 2011 Virtual Fiber is a term that describes wireless data transmission comparable in data throughput to optic fiber . The term was coined in El Salvador , Central America to describe a communications network service provided by Five Nines Communications, S.A. de C.V. Wireless data transmission is used for mobile telephony , mobile internet service, monitoring, and security applications to name a few. Present applications for Virtual Fiber or Fibra Virtual as it is known in Spanish language Spanish are being developed with Salvadoran governmental agencies in order to service educational centers that currently have no access to hard wired Internet or telephone service. Virtual Fiber installations avoid the need to install expensive fiber or cabled networks in order to access areas not currently covered by existing networks and are a more efficient option to traditional wireless or hard wired installations. Another advantage of Virtual Fiber is the fact that it can carry a vast array of signalling protocol s within the electromagnetic spectrum and it is not limited by legacy issues.

Basalt fiber or fibre is a material made from extremely fine fiber s of basalt , which is composed of the mineral s plagioclase , pyroxene , and olivine . It is similar to Carbon fiber carbon fiber and Glass fiber fiberglass , having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber. It is used as a Fireproofing fireproof textile in the aerospace and automotive industries and can also be used as a Composite material composite to produce products such as Tripod photography camera tripods . Manufacture Basalt fiber is made from a single material, crushed basalt, from a carefully chosen quarry source and unlike other materials such as glass fiber, essentially no materials are added. The basalt is simply washed and then sent to be melted down. ref http www.compositesworld.com articles basalt fibers alternative to glass ref The manufacture of basalt fiber requires the melting of the quarried basalt rock at about convert 1400 C F . The molten rock is then Extrusion extruded through small nozzles to produce continuous filaments of basalt fiber. There are three main manufacturing techniques, which are centrifugal blowing, centrifugal multiroll and die blowing. The fibers typically have a filament diameter of between 9 and 13 micrometre m which is far enough above the respiratory limit of 5 m to make basalt fiber a suitable replacement for asbestos . They also have a high elastic modulus , resulting in excellent specific strength specific tenacity three times that of steel .

Unreferenced date December 2009 Orphan date February 2009 Fiber simulation is a branch of mechanics that deals with modeling the dynamics mechanics dynamics and rheology of particles of large aspect ratio, or fibers with the goal of predicting the properties of fiber suspensions and networks based on first principles . Simulation of fiber suspensions have applications in paper industry and also in Composite material composites , including composites made of carbon nanotubes . Many of the models used to simulate fibers were developed by researchers in the field of rheology . Rheologically speaking fiber suspensions are non Newtonian fluid s, and can display normal stress differences. Early fiber simulations employed particles which were rigid rods or prolate spheroids , whose equation of motion equations of motion have analytical solutions. More recent models are able to represent flexible fibers. The models rely heavily on continuum mechanics concepts and the numerical methods employed have some similarities to those employed in molecular dynamics , or in dynamics of multi body systems. The use of computers facilitates greatly the solution of fiber simulation problems. The complexity of the simulations arise from the system having a large number of degrees of freedom physics and chemistry degrees of freedom , and from the numerous possible interparticle interactions having place, such as friction , hydrodynamic interactions, and other kinds of interparticle forces such as colloidal forces that exert attractive or repulsive forces.

M5 fiber polyhydroquinone diimidazopyridine is a high strength synthetic fiber first developed by Dr. Doetze Sikkema ref name cummins http web.mit.edu course 3 3.91 www slides cunniff.pdf ref and his team at the Dutch chemical firm Akzo Nobel. Currently, it is being produced by the United States Magellan Systems International LLC. Preparation M5 fiber is prepared by a Dehydration reaction condensation polymerization between tetraaminopyridine and dihydroxyterephthalic acid using diphosphorus pentoxide as a dehydrating agent. The polymer mixture is then heated and extruded to form brightly blue polymer fibers. The fibers are then washed extensively with water and base in order to remove the phosphoric acid generated by the hydration of diphosphorus pentoxide from the polymer. In order to remove the water from the fiber structure and enable the intermolecular hydrogen bonds to be created and thus greatly increase the strength of the polymer, the fiber is heated and exposed to controlled stress. This aligns the fibers in the optimal configuration. Properties M5 is stronger than Aramid Kevlar , Twaron and UHMWPE Dyneema , Spectra . M5 is more fire resistant than meta Aramid. It is the most fire resistant organic fiber yet developed. It is less brittle than carbon fiber and will yield when stretched.

CTF3 Cuben Fiber is a product marketed and developed by the Cuben Fiber and Cubic Tech Corporations as a high performance non woven fabric for applications such as yacht sails, airship hulls, kites and many designs that require extremely strong rip resistance and light areal weight. History The name Cuben Fiber was coined by the press in reference to America C2 B3 America pronounced America Cubed , the winner of the 1992 America s Cup . During the 1992 Cup, that yacht reportedly used sails made from precursors to the currently available commercial product. In late 2007, the Cuben Fiber Corporation was acquired by North Sails. North Sails says they will continue to supply the materials to competitors on an as available basis. Cubic Tech Corporation has the exclusive rights to develop and sell Cuben Fiber type laminates for all non sailing applications. Production Cuben Fiber is a laminated fabric constructed from Ultra High Molecular Weight Polyethylene UHMWPE fiber monofilaments and polyester, PVF etc. films. Cuben fiber is sometimes confused with carbon fiber , one of the many fibers used as a reinforcement in some Cuben Fiber laminates. Cubic Tech Corporation s ultra high performance flexible laminates were re branded from Cuben Fiber to CTF3 TM in 2009. Cubic Tech Corp produces CTF3 with a wide variety of fibers such as Vectran, Carbon, Kevlar etc. Uses The material is used in yachting , performance sailing, windsurfing , inflatables, airship hulls, medical applications and increasingly in ultralight backpacking equipment, such as tents etc. Similar to sails made from traditional woven sail cloth, Cuben Fiber sails are constructed from panels that are bonded and sewn together, as opposed to 3DL sails that are laminated over a mold.

They are associated with cold and pressure, and as nociceptors stimulation of them is interpreted as fast first pain information. They are thinly myelin ated, so conduct signals more rapidly than unmyelinated C fiber s, but more slowly than other, more thickly myelinated A class fibers. The fibers terminate at Rexed lamina I. Structure They are thin, myelin ated axons with a moderate conduction velocity , or speed of travel of a nerve signal 2 to 30 m s . These nerve fibers are associated with acute sharp Pain and nociception pain and therefore constitute the afferent portion of the reflex arc that results in pulling away from noxious stimuli e.g. yanking hand away from hot stove . A certain proportion of A fibers are also associated with sensations of temperature also known as cold receptors in mammals and pressure .
