Yiziphi izigaba ze-carbon fibre materials?

I-Carbon fiber ingahlukaniswa ngokuya ngobukhulu obuhlukahlukene njengohlobo lukasilika eluhlaza, indlela yokukhiqiza, nokusebenza.

1. Ihlukaniswe ngokohlobo lwesilika eluhlaza: isisekelo se-polyacrylonitrile (PAN), isisekelo se-pitch (isotropic, mesophase);isisekelo se-viscose (isisekelo se-cellulose, isisekelo se-rayon).Phakathi kwazo, i-polyacrylonitrile (PAN)-based carbon fiber ithatha isikhundla esijwayelekile, ngokukhipha okungaphezulu kuka-90% wengqikithi ye-carbon fiber, kanye ne-viscose-based carbon fiber ingaphansi kuka-1%.

2. Ihlukaniswa ngokwezimo nezindlela zokukhiqiza: i-carbon fibre (800-1600°C), i-graphite fiber (2000-3000°C), i-activated carbon fibre, kanye ne-vapor-phase ekhuliswe i-carbon fiber.

3. Ngokwezakhiwo zemishini, ingahlukaniswa ngezinhlobo ezijwayelekile-inhloso kanye nokusebenza okuphezulu: amandla e-carbon fibre yenhloso ejwayelekile yi-1000MPa, i-modulus imayelana ne-100GPa;uhlobo olusebenza kahle kakhulu luhlukaniswe ngohlobo lwamandla aphezulu (amandla 2000MPa, modulus 250GPa) kanye nemodeli ephezulu (modulus 300GPa noma ngaphezulu), lapho amandla amakhulu kuno-4000MPa abizwa nangokuthi uhlobo lwamandla aphezulu, kanye nemodulus enkulu kune-450GPa ibizwa nge-ultra-high model.

4. Ngokusho kobukhulu be-tow, ingahlukaniswa ibe i-tow encane kanye ne-tow enkulu: i-tow encane ye-carbon fiber ikakhulukazi i-1K, i-3K, ne-6K esigabeni sokuqala, futhi kancane kancane ikhula ibe ngu-12K no-24K.Isetshenziswa kakhulu kwi-aerospace, ezemidlalo kanye nezokungcebeleka neminye imikhakha.Imicu yekhabhoni engaphezu kuka-48K ivamise ukubizwa ngokuthi ama-tow carbon fibers amakhulu, okuhlanganisa i-48K, 60K, 80K, njll., esetshenziswa kakhulu emikhakheni yezimboni.

5. Amandla okuqina kanye ne-tensile modulus yizinkomba ezimbili ezibalulekile zokulinganisa ukusebenza kwe-carbon fiber.

Okungenhla okuqukethwe kokuhlukaniswa kwezinto ze-carbon fibre ezethulwe kuwena.Uma ungazi lutho ngakho, wamukelekile ukuthi uxhumane nesizindalwazi sethu, futhi sizoba nabantu abangochwepheshe abazokuchazela ngakho.
