How do air parcels respond to a horizontal air pressure gradient? A horizontal pressure gradient refers to air pressure changes along a surface of constant altitude. The horizontal wind is governed by interactions of the pressure gradient force, centripetal force, Coriolis Effect, friction, and gravity. The pressure gradient force initiates air motion and arises in part from spatial variations in air temperature and, to a lesser extent, water vapor concentration.
Carbon fiber was invented in 1958 by Roger Bacon. It used Rayon  fibers which where heated until carbonized to create a highly  durable and strong material.
Raw Materials. Carbon fiber is made from organic polymers, which consist of long strings of molecules held together by carbon atoms. Most carbon fibers (about 90 percent) are made from the polyacrylonitrile (PAN) process. A small amount (about 10 percent) are manufactured from rayon or the petroleum pitch process.arbon fibers have high tensile strength and are very strong for their size. In fact, carbon fiber might be the strongest material there is. Each fiber is 5-10 microns in diameter. To give a sense of how small that is, one micron (um) is 0.000039 inches.
