{{Short description|Composite material that has load-carrying and other functions as well}}

A '''Multimulti-function material''' is a [[composite material]]. The traditional approach to the development of structures is to address the loadcarryingload-carrying function and other functional requirements separately. Recently, however, there has been increased interest in the development of load-bearing materials and structures which have integral non-load-bearing functions, guided by recent discoveries about how multifunctional [[biological system]]s work.<ref name="Gibson 2010 pp. 2793–2810">{{cite journal | last=Gibson | first=Ronald F. | title=A review of recent research on mechanics of multifunctional composite, Journalmaterials ofand structures | journal=Composite Structures | publisher=Elsevier BV | volume=92 (| issue=12 | year=2010) | issn=0263-8223 | doi=10.1016/j.compstruct.2010.05.003 | pages=2793–2810}}</ref>

==Functions==

Among the many functions that can be attained are Electricalpower transmission, [[electrical conductivity|electrical]]/[[thermal conductivity]], Sensingsensing and actuation, Energyenergy harvesting/storage, Selfself-healing capability, Electromagneticelectromagnetic interference (EMI) shielding and recyclability and [[biodegradability]]. See also [[Functionallyfunctionally graded material| Functionally graded materials (FGM)]]s which are [[composite materials]] where the composition or the microstructure are locally varied so that a certain variation of the local material properties is achieved.<ref>{{Cite journal |last1=Chaudhary |first1=Birendra |last2=Matos |first2=Helio |last3=Das |first3=Sumanta |last4=Owens |first4=Jim |date=2023-06-01 |title=Multifunctional carbon/epoxy composites with power transmission capabilities |journal=Materials Today Communications |volume=35 |pages=105665 |doi=10.1016/j.mtcomm.2023.105665 |issn=2352-4928|doi-access=free }}</ref><ref>[http://www.oeaw.ac.at/esi/english/research/materials/comp/fgms.html O.

Many applications such as Rere-configurable aircraft wings, shape-changing aerodynamic panels for flow control, Variablevariable geometry engine exhausts, turbine blade, wind turbine configuration at different wind speed, Microelectromechanicalmicroelectromechanical systems (micro-switches), mechanical memory cells, valves, micropumps,Flexible flexible direction panel position in solar cells,Innovative innovative architecture (adaptive shape panels for roofs and windows), Flexibleflexible and foldable electronic devices and Opticsoptics (shape changing mirrors for active focusing in adaptive optical systems).
