Editing Carbon fibers (section)

===Composite materials===
Carbon fiber is most notably used to reinforce [[composite material]]s, particularly the class of materials known as [[Carbon fiber reinforced polymer|carbon fiber or graphite reinforced polymers]]. Non-polymer materials can also be used as the matrix for carbon fibers. Due to the formation of metal [[carbide]]s and [[corrosion]] considerations, carbon has seen limited success in [[metal matrix composite]] applications.  [[Reinforced carbon-carbon]] (RCC) consists of carbon fiber-reinforced graphite, and is used structurally in high-temperature applications. The fiber also finds use in [[filtration]] of high-temperature gases, as an [[electrode]] with high surface area and impeccable [[corrosion]] resistance, and as an anti-[[Triboelectric effect|static]] component. Molding a thin layer of carbon fibers significantly improves fire resistance of polymers or thermoset composites because a dense, compact layer of carbon fibers efficiently reflects heat.<ref>{{cite journal |last1=Zhao |first1=Z. |last2=Gou |first2=J. |title=Improved fire retardancy of thermoset composites modified with carbon nanofibers|journal= Sci.

The increasing use of carbon fiber composites is displacing aluminum from aerospace applications in favor of other metals because of [[galvanic corrosion]] issues.<ref>{{cite magazine |url=http://www.boeing.com/commercial/aeromagazine/aero_07/corrosn.html |title=Design for Corrosion |magazine=Aero |publisher=Boeing |issue=7 |date=July 1999 |last1=Banis |first1=David |last2=Marceau |first2=J.

Carbon fiber can be used as an additive to asphalt to make electrically conductive asphalt concrete.<ref>{{cite journal |title=Effect of Carbon-Fiber Properties on Volumetrics and Ohmic Heating of Electrically Conductive Asphalt Concrete |first1=Mohammad Ali |last1=Notani |first2=Ali |last2=Arabzadeh |first3=Halil |last3=Ceylan |first4=Sunghwan |last4=Kim |journal=Journal of Materials in Civil Engineering |location=US |volume=31 |issue=9 |pages=04019200 |date=June 2019 |doi= 10.1061/(ASCE)MT.1943-5533.0002868|s2cid=198395022 }}</ref> Using this composite material in the transportation infrastructure, especially for airport pavement, decreases some winter maintenance problems that lead to flight cancellation or delay due to the presence of ice and snow. Passing current through the composite material 3D network of carbon fibers dissipates thermal energy that increases the surface temperature of the asphalt, which is able to melt ice and snow above it.<ref>{{cite journal |title=Electrically conductive asphalt concrete: An alternative for automating the winter maintenance operations of transportation infrastructure |first1=Ali |last1=Arabzadeh |first2=Mohammad Ali |last2=Notani |first3=Ayoub Kazemiyan |last3=Zadeh |first4=Ali |last4=Nahvi |first5=Alireza |last5=Sassani |first6=Halil |last6=Ceylan |journal=Composites Part B: Engineering |location=US |volume=173 |pages=106985 |date=2019-09-15 |doi=10.1016/j.compositesb.2019.106985|s2cid=189994116 |url=https://lib.dr.iastate.edu/cgi/viewcontent.cgi?article=1233&context=ccee_pubs }}</ref>
