Ungazihlola kanjani izakhiwo zemishini zegrafu enwetshiwe. Ukuhlolwa kwamandla okusheshayo kwesithombe esinwetshiwe kufaka umkhawulo wamandla we-Tensile, i-Tensile Elastic Modulus kanye nokunwebeka kwezinto ze-graphite ezinwetshiwe. Isihleli esilandelayo segrafu furuite sethula indlela yokuhlola izakhiwo zemishini zegrafu enwetshiwe:
Kunezindlela eziningi zokuhlolwa okuthe xaxa zezindawo ezisebenza ngemishini zegrafu ezandisiwe, njengokulinganisa kwemishini, i-laser scecle, ukuphazanyiswa nokunye. Ngemuva kokuhlolwa okuningi nokuhlaziywa, kutholakala ukuthi idatha yamandla ashubile ingatholakala kangcono ngokuhlolwa okuthe xaxa kwesigaba se-graphite ayi-125. Umkhawulo wamandla we-Tensile ubhekisa emthwalweni wamandla amakhulu ashubile acatshangelwe yindawo ngayinye, kanti usayizi wawo kungenye yezinkomba ezibalulekile zokulinganisa ngokuphelele izakhiwo zemishini.
Ukuhlolwa kwe-Tensile Elastic Modulus kungathola inani elilinganiselwe le-Tensile Elastic Modulus ngejika le-strein-streain etholwe ekuhlolweni kwezinye izisulu ze-graphimens ezithuthukisiwe ze-graphimes kanye nendlela eqinile yangemuva. Idatha yezibalo ye-elongation ingatholakala ngokuhlola ama-graphimens angama-42 anwetshiwe anwetshiwe.
I-graphite enwetshiwe ekhiqizwa yi-graphite ye-furuite inezakhiwo ezinhle kakhulu futhi isetshenziswa kabanzi, phakathi kwayo i-meher-mechanical proceties, ifaka phakathi amandla okucindezela, ukuqina kwe-modulus, ukuqina kanye nokucindezelwa isilinganiso sokushisa okuphezulu kwesikhathi esithile.
