Ukuthelekisa ukusebenza kwetyhubhu ye-carbon fiber kunye ne-glass fiber tube

Ityhubhu yekhabhoni yefayibha kunye nombhobho wefiber yeglasi ziindlela ezimbini zokusetyenziswa kweetyhubhu ezidibeneyo.Ityhubhu ye-carbon fiber yenziwa ngokujija, i-pultrusion okanye ukujijwa kwe-carbon fiber prepreg, ngelixa ityhubhu yefayibha yeglasi izotywa kwaye ikhutshwe yi-glass fiber kunye ne-resin.Imibhobho yezi zinto zimbini isetyenziswa ngokubanzi kwi-aerospace, ukuveliswa kweemoto, ezemidlalo kunye namanye amashishini.Nguwuphi umahluko ekusebenzeni kwabo?

Uxinaniso lwetyhubhu ye-carbon fiber yi-1.6g/cm ³, engaphantsi kwaleyo yealloyi ye-aluminiyam, ukomelela kombhobho wentsimbi yi-300 ~ 600MPa, amandla okuqina ombhobho wealluminiyam yi-110 ~ 136MPa, kunye namandla okuqina ityhubhu ye-carbon fiber imalunga ne-1500MPa.I-coefficient yokwandisa i-thermal ye-carbon fiber composite yi-1.4 × 10 ^ -6, enokuqinisekisa ukuba ubungakanani bemveliso buzinzile kwaye akulula ukuphazamisa.Umda wamandla wokudinwa we-carbon fiber tube yi-70% ~ 80% yamandla ayo okuqina.Xa usebenza phantsi komthwalo oguqukayo wexesha elide, ityhubhu ye-carbon fiber izinzile kwaye inobomi obude benkonzo.Kwaye izinto zekhabhoni zefiber zinokusebenza kakuhle kombane kunye nokusebenza okugqwesileyo kwe-electromagnetic shielding.

Ubuninzi betyhubhu yefiber yeglasi 2.53 ~ 2.55g/cm ³inzima kunobo betyhubhu yefayibha yekhabhoni yolwazi olufanayo, amandla okuqina 100 ~ 300MPa, imodyuli ye-elasticity 7000MPa, ulwabelo kwikhefu yi-1.554%, umlinganiselo wePoisson ongu-0.22, ukwandiswa kwe-coefficient ye-thermal ye-coefficient 4.8×10 ^-4.Uxinzelelo nalo lukhulu kakhulu, kwaye xa ubunzima bufikelela kwi-1% ~ 2%, i-resin iya kuphuka, ngoko ke uxinzelelo oluvumelekileyo lwe-glass fiber tube aludluli i-60% yoxinzelelo lomda, ngelixa i-carbon fiber tube ine- imodulus enkulu elastiki kwaye inokugcina iipropathi ezilungileyo zoomatshini phantsi komda woxinzelelo lwemeko.

Ukushwankathela, ityhubhu yefayibha yekhabhoni ineenzuzo ezingaphezulu kunetyhubhu yefiber yeglasi kwiipropathi zomatshini, kodwa nganye inentsimi yayo yesicelo, umzekelo, ityhubhu yefiber yeglasi iyadingeka kwindawo apho kufuneka ukufakelwa.
