simulation of outside of space shuttle heats on 1500 °c during re-entry
a cloth of woven carbon fiber filaments, common element in composite materials
composite materials contain 2 or more macroscopic phases, 1 of ceramic. example, continuous matrix, , dispersed phase of ceramic particles or fibers.
applications of composite materials range structural elements such steel-reinforced concrete, thermally insulative tiles play key , integral role in nasa s space shuttle thermal protection system used protect surface of shuttle heat of re-entry earth s atmosphere. 1 example reinforced carbon-carbon (rcc), light gray material withstands reentry temperatures 1510 °c (2750 °f) , protects nose cap , leading edges of space shuttle s wings. rcc laminated composite material made graphite rayon cloth , impregnated phenolic resin. after curing @ high temperature in autoclave, laminate pyrolized convert resin carbon, impregnated furfural alcohol in vacuum chamber, , cured/pyrolized convert furfural alcohol carbon. in order provide oxidation resistance reuse capability, outer layers of rcc converted silicon carbide.
domestic examples of composites can seen in plastic casings of television sets, cell-phones , on. these plastic casings composite made of thermoplastic matrix such acrylonitrile butadiene styrene (abs) in calcium carbonate chalk, talc, glass fibers or carbon fibers have been added strength, bulk, or electro-static dispersion. these additions may referred reinforcing fibers, or dispersants, depending on purpose.
thus, matrix material surrounds , supports reinforcement materials maintaining relative positions. reinforcements impart special mechanical , physical properties enhance matrix properties. synergism produces material properties unavailable individual constituent materials, while wide variety of matrix , strengthening materials provides designer choice of optimum combination.
