Ingakanani iqondo lokushisa eliphezulu elinokumelana ne-carbon fiber, kutheni iimveliso ezininzi ze-carbon fiber azikwazi ukumelana nobushushu obuphezulu

Ubushushu obuphezulu bunokumelana kangakanani ne-carbon fiber
Ifayibha yeCarbon ngokwayo inokumelana nobushushu obuphezulu kakhulu, kwaye kunokuthiwa yinto exhathisa ubushushu obuphezulu kakhulu, kodwa imathiriyeli yekhabhoni yefiber composite ixhomekeke kwimatrix.
I-Yan F cone ikhupha imathiriyeli ekrwada kwi-petroleum kunye namalahle.Okokuqala, i-polyacrylonitrile ikhutshwe, kwaye i-carbon fiber ikhutshwe nge-polyacrylonitrile.Iimfuno zobugcisa apha ziphezulu kakhulu, kwaye i-oxidation, i-carbonization kunye ne-graphitization kuyo yonke inkqubo yonke Ifuna ubushushu obuphezulu ukugqiba, ngakumbi phantsi kobushushu obuphezulu beqondo lamawaka aliqela lokumbiwa kwamatye, emva kokususa iphephancwadi, i-carbon fiber tow. Ifunyenwe, ngoko ke i-carbon fiber ngokwayo inokumelana nobushushu obuphezulu kakhulu, inokumelana nobushushu obuphezulu be-3000 ℃, kwaye inokugcina inzuzo yokusebenza kakuhle.
Kutheni iimveliso ezininzi ze-carbon fiber zingaxhathisi ukushisa okuphezulu?
Njengoko kukhankanyiwe ngasentla, i-carbon fiber inokumelana nokushisa okulungileyo kunye nokuphezulu.Kwimveliso yeemveliso ze-carbon fiber, akusiyo nje into ye-carbon fiber.Isixhobo se-matrix siyafuneka ukuze kugqitywe ukuveliswa kweemveliso zefiber kade.Iimveliso zekhabhoni zefiber zixhathisa kumaqondo obushushu aphezulu.Cinga ukumelana nobushushu obuphezulu bezinto ezisisiseko.
Inyaniso yokuba iimveliso ezininzi ze-carbon fiber azibumbi kwaye zifudumeze ngenxa yokuba izinto ezidibeneyo ze-carbon fiber zininzi ze-carbon fiber + i-resin-based composite materials, kunye nomxholo we-fiber yasemva kwexesha kwi-composite material malunga ne-40% -45%, ngoko ke. imveliso Ukumelana nokushisa okuphezulu kweemveliso ze-carbon fiber ezigqityiweyo zihambelana nokumelana nokushisa okuphezulu kwe-resin.Oku kufana nomgaqo wemibhobho yokhuni.Umda wokumelana nobushushu obuphezulu be-resin ube ngumda ophezulu wokumelana nobushushu obuphezulu beemveliso ze-carbon fiber.
Kwiimeko eziqhelekileyo, ukuxhathisa ubushushu obuphezulu be-resin matrix malunga ne-180C.Ukuba idlula eli qondo lokushisa ixesha elide, liya kubangela ukuba i-resin matrix inyibilike, eya kuchaphazela ukusebenza kokugqibela kwemveliso.
Ukongezelela, ukwenzela ukuba kuphuculwe ngakumbi ukuchasana kweqondo lokushisa eliphezulu, isiseko somthi womthi siya kukhetha i-matrix enokumelana nokushisa okuphezulu, oko kukuthi, iplastiki ekhethekileyo.Ukuba unezinto ze-matrix ezineenzuzo eziphezulu zokusebenza ezifana ne-PEK kunye ne-PPS, ngoko ke iimveliso ze-carbon fiber eziveliswayo ziya kuxhathisa Ukushisa kunokufikelela ngaphezu kwe-20YC.Ukuba ubushushu obuphezulu bufunekayo, i-carbon-based okanye i-ceramic matrix yensimbi kufuneka ikhethwe.Ukumelana nokushisa okuphezulu okunjalo kunokuba ngcono.
