Could you explain simply please?
Um.Oxygen will lose electrons to form O2 and Al3+ will gain electrons to form Al(s) Hope this helps :) XXXXXXXXXXXXXXXXXXXXXXXXXXXX
Carbon fiber is made from organic polymers, which consist of long strings of molecules held together by carbon atomsMost carbon fibers (about 90 percent) are made from the polyacrylonitrile (PAN) processA small amount (about 10 percent) are manufactured from rayon or the petroleum pitch processGases, liquids, and other materials used in the manufacturing process create specific effects, qualities, and grades of carbon fiberThe highest grade carbon fiber with the best modulus properties are used in demanding applications such as aerospaceIn the manufacturing process, the raw materials, which are called precursors, are drawn into long strands or fibersThe fibers are woven into fabric or combined with other materials that are filament wound or molded into desired shapes and sizesThere are typically five segments in the manufacturing of carbon fibers from the PAN processThese are: -SpinningPAN mixed with other ingredients and spun into fibers, which are washed and stretched-StabilizingChemical alteration to stabilize bonding-CarbonizingStabilized fibers heated to very high temperature forming tightly bonded carbon crystals-Treating the SurfaceSurface of fibers oxidized to improve bonding properties-SizingFibers are coated and wound onto bobbins, which are loaded onto spinning machines that twist the fibers into different size yarnsInstead of being woven into fabrics, fibers may be formed into compositesTo form composite materials, heat, pressure, or a vacuum binds fibers together with a plastic polymer I hope I helped
