Adamantite ! Rearden Metal ! Uru ! Durasteel ! Dalekanium ! Unobtanium ! Thousands of fictional characters have fought and died for these equally fictional super - fabric . So what is the literal - life strongest content on our puny , sun - warmed planet ?
Mankind ’s pursuit of the “ unattackable ” material has n’t exctly been a concerted , organized movement , but it figures into chronicle in unbelievably sound ways . hellhole , anyone who ’s act Age of Empires or civilisation — or show a book — knows that historian name entire eras after materials . The Iron ( and blade ) Age follow the Bronze Age , which followed the Copper Age . Materials got secure , and mankind get ahead . The two were hugely correlated .
It ’s been a while since we ’ve had a good ol’ textile - found date of reference . Too long ! So have ’s recover the next one . Goodbye Age of Computers , hello Age of _ _ _ _ _ _ _ _ .
To say that a cloth is “ strong ” describes so many different things that it can end up meaning nothing . A piece of trash is stronger than a piece of music of string cheese in one way , but not another . Spiderweb may be strong than blade in a particular trial , but it ’s still a bendy , slick mess . So what do we mean when we mouth about strength ?
Mark Hersam , Professor of Materials Science ( and Chemistry ) at Northwestern University , has an result . Well , a few answer : “ Typically when mass talk about strength , they ’re talking about the amount of stress that needs to be put on before fracture . It ’s possible they could also be refer to how quickly it turn . ” It ’s also possible that they could be talk about compressive strength , which is a measure of how leisurely it is for a cloth to get crushed . You could even be referring to impact strength , which is a fabric ’s power to corroborate a sudden smack . Arg ! Make up your mind , people !
fortuitously , the 20/20 hindsight of account can steer us onward . Remember our ages ? Iron , blade , copper , bronze — these are cloth that we make thing out of , be they social organisation or instruments . Hard thing . elusive things : swords or trucks or skyscrapers or bridges . We ’re looking for rigourousness , yield strength — that ’s resistance to distortion , like indent or extend — and ductile strength , which essentially refers to flex . A stuff of world star strength would be an optimal loan-blend of these two qualities .
Tungsten carbide is phenomenally hard and has majuscule takings strength , but is worryingly brickly when smashed or bent . Os alloy follow that same trend : extremely hard , but shatterable and lacking in true tensile strength . Diamonds are harder than either , but nearly impossible to work with or apply in virtual products and very , very uncommon . ( Ever try of a wrought infield ? A baseball diamond fighter spurt ? Right . )
Ti alloys can be flexible and sport high tensile military posture , but are n’t as hard as brand admixture . Amorphous alloys like Liquidmetal , Apple ’s new squeeze , are among the strongest materials all - around , with sizable hardness , Brobdingnagian tensile strength and resistance to fatigue — though it ’s not superlative in any way . Every metal has its impuissance , is what I ’m saying .
The real super - materials , well , they do n’t quite live yet . But we ’re getting closer . You ’ve belike listen a mickle about graphenein the last few weeks , after a couple of scientists come through Nobel Prizes for their work with the material . You ’ve plausibly listen that it ’s hard . ( 200x hard than brand . ) That it ’s flexible . That it conducts electrical energy , and fall out to be transparent . What you ’ve believably heard , in a nutshell , is that it ’s awesome . It has quick and obvious applications in electronics , and Andre Geim , one of the recipient role of the prize , went so far as to tell the AP , “ [ Graphene ] has all the potential to change your life in the same way that plastics did . ”

The trial that two year ago led to thedeclarationof graphene as the world ’s strongest material was a test of a one - atom - thick rag of the stuff . Had the experimentation withdraw place on a ( theoretical ) magnanimous scale , the number would scale up favourably . An inch - thick block of cloth with graphene ’s property would be nigh durable . Thing is , such a sheet ca n’t subsist .
“ The property [ of strength ] is nominally self-governing of the geometry , but the problem is that the app emphatically depend on the geometry , ” tell Hersam . And what he intend , in English , is that while graphene in amazingly strong , this strength ca n’t easy be conform to real , utile coating . Graphene is by definition a canvass of atomic number 6 atoms , bring together in a particular manner , but always one particle duncical . If you seek to stack these sheets together , they can bond , but not well . Stacked graphene is called flake black lead — pencil atomic number 82 , basically . And you ca n’t work up a bridge or a gun or a satellite out of pencil lead .
But wait ! All is not lost for graphene . Not nearly . “ Graphene has to be incorporated into some matrix — a polymer , or a metal , ” says Hersamin . fundamentally , in social club for it to be used in the real reality , the material require to become a factor of something else . The trick will be maintaining its striking mechanical property while it ’s disseminate inside another material .
This , he enounce , is an overt question . Everybody ’s excited about graphene , but nobody ’s building graphene smartphones — yet . “ If you’re able to sew the graphene into a plastic or into a metal in such a way that the load of the plastic or metal would transfer to the graphene , so that the graphene in reenforcing the bulk of the material , ” then you ’d might have yourself a A-one - textile .
carbon copy nanotubes have long been held to have similar potential , but progress has n’t been nifty . You ’ll see C - carbon nanotube gear at the top echelons of some sports , but it ’s a luxury , and its benefits — particularly when it get along to strength — aren’t exactly huge . for get the nanotube to stick to with other materials , the bonding within the carbon nanotube themselves has to be compromise fairly . It ’s a bit of a Catch-22 , and graphene is every bit as vulnerable to the same fate ; because nanotubes , to put it crudely , are just turn over - up flat solid of graphene .
Some interest that graphene will suffer this same destiny : a lone textile ineffective to find a suitable matrix - teammate for years , the promise of its youth spread thin over time as enthusiasm for its charm wane … But for now , the mood is optimistic . Some researchers , Hersam says , already consider they ’ve follow up with a way to sew the graphene into a ground substance without drastically vary its mechanical dimension , but their thesis is new , and so far young . It does seem to be the lawsuit , though , that the two - dimensionally arranged carbon speck in graphene will be more forgiving than nanotubes , as far as fabric scientists are concerned .
The take - away is that graphene gear will never be possible , but something that is some like graphene may one Clarence Day be used to build up all kinds of things . And even then , it ’ll be difficult to say that it ’s the hard material in the world . Its carbon - first cousin , diamond , may still be intemperate ; sealed metals may have more or less higher tensile strength . It might not arrogate a single record , or make for a great deed for an era ( The Graphene Composite 1.0 Age ? ) , but it ’ll be secure . Not the hard , or the most resistant to deformation . Just .. really warm .
