Indlela yokuvavanya iimpawu zoomatshini zegrafiti eyandisiweyo. Uvavanyo lwamandla okutsalwa kwegrafiti eyandisiweyo luquka umda wamandla okutsalwa, imodulus ye-tensile elastic kunye nokwandiswa kwezinto zegrafiti eyandisiweyo. Lo mhleli ulandelayo weFuruite Graphite uzisa indlela yokuvavanya iimpawu zoomatshini zegrafiti eyandisiweyo:
Kukho iindlela ezininzi zokuvavanya ukutsalwa kweempawu zoomatshini zegrafiti eyandisiweyo, njengokulinganisa ngoomatshini, i-laser speckle, ukuphazamiseka njalo njalo. Emva kovavanyo oluninzi kunye nohlalutyo, kufunyaniswe ukuba idatha yamandla okutsalwa ingafumaneka ngcono ngovavanyo lokutsalwa kwegrafiti ye-worm eyi-125. Umda wamandla okutsalwa ubhekisa kumthwalo wamandla amakhulu okutsalwa anokuthwalwa yisampuli kwindawo nganye, kwaye ubukhulu bayo yenye yezona zikhokelo zibalulekileyo zokulinganisa ngokupheleleyo iimpawu zoomatshini zezinto zegrafiti eyandisiweyo.
Uvavanyo lwe-tensile elastic modulus lunokufumana ixabiso eliqikelelweyo le-tensile elastic modulus ngokusebenzisa i-stress-strain curve efunyenwe kuvavanyo lwe-tensile lweesampuli ze-graphite ezandisiweyo ezingama-83 kunye nendlela ye-rigid secant. Idatha yezibalo yokwandiswa ingafunyanwa ngokuvavanya iisampuli ze-graphite ezandisiweyo ezingama-42.
Igrafiti eyandisiweyo eveliswa yigrafiti yeFuruite ineempawu ezintle kakhulu kwaye isetyenziswa kakhulu, phakathi kwazo iipropati zoomatshini ezinobushushu obuphezulu, ezikwabizwa ngokuba ziimpawu zoomatshini, ziquka amandla okuxinzelela, imodulus yokuxinzelela ethambileyo, ukuqina kunye nomlinganiselo wokuxinzelela kubushushu obuphezulu kangangexesha elithile.
