Carbon fiber prepreg yog ib qho khoom nruab nrab uas tsim los ntawm impregnating carbon fiber bundles rau hauv ib lub matrix resin. Nws feem ntau yog kho prepreg nrog qis kub. Cov ntaub ntawv ua ntej impregnated yuav dhau qee qhov kev hloov pauv ntawm qhov sib txawv ntawm qhov kub thiab txias, thiab qhov kub siab dua, lub sijhawm luv ntawm cov tshuaj tiv thaiv. Txhawm rau khaws cov pa roj carbon fiber ntau prepreg rau lub sijhawm ntev, nws yog ib qho tsim nyog yuav tsum tuav lub tub yees thaum thauj, khaws cia, thiab lwm yam txheej txheem.

Cov pa roj carbon fiber ntau prepreg yuav tsum tau khaws cia ntawm qhov kub thiab txias, nrog lub sijhawm cia tsuas yog ib hlis ntawm chav tsev kub (25 degree); Raws li qhov xwm txheej ntawm -5 degree rau 0 degree, lub sijhawm khaws cia tuaj yeem txuas ntxiv mus rau 3 lub hlis; Yog tias qhov ntsuas kub qis dua -18 degree, lub sijhawm khaws cia tuaj yeem txuas ntxiv mus rau ntau dua 6 lub hlis.

Feem ntau, cov tuam txhab carbon fiber ntau muaj cov chaw cia txias kom khaws cov pa roj carbon fiber prepregs. Tsis tas li ntawd, thaum lub sijhawm thauj mus los, cov tsheb yuav tsum tau nruab nrog cov ntsuas kub thiab av noo. Thaum tau txais prepregs, cov tuam txhab yuav tsum tau txais cov ntaub ntawv los ntawm cov cuab yeej kaw thiab tshuaj xyuas qhov chaw thauj mus los, ntsuas qhov seem txee lub neej ntawm prepregs, thiab pab txhawb kev tsim thiab ua tiav cov phiaj xwm tsim khoom tom ntej.

Carbon fiber prepreg yuav tsum tau thawed ua ntej siv

Carbon fiber ntau prepreg yuav tsum tau tag nrho decomposed thiab khov ua ntej siv los qhib lub viscosity ntawm prepreg kom ua tiav cov txheej txheem kev ua tau zoo. Feem ntau, muaj cov kev xav tau meej thiab kev tswj xyuas qhov kub thiab txias thiab lub sijhawm ntawm thawing. Yog tias qhov kub thiab txias dhau lawm, nws tuaj yeem ua rau lub neej kev pab cuam ntawm carbon fibers lossis ncaj qha ua rau cov khoom ua kom khov thiab poob nws txoj haujlwm. Yog tias qhov ntsuas kub tsawg dhau, nws yuav tsis ua raws li qhov yuav tsum tau ua ntawm kev siv.

Txoj kev thawing tshwj xeeb tsis yog qhov nyuaj. Qhib lub thawv ntim khoom sab nrauv ntawm cov khoom prepreg, tag nrho nthuav tawm cov pa roj carbon fiber ntau prepreg rau qhov cua sov ib puag ncig, ntsuas qhov kub ntawm cov khoom tsis tu ncua thaum lub sijhawm cua sov, thiab thaum kawg nce qhov kub ntawm cov khoom mus rau chav tsev kub lossis qhov tsim nyog kub. los ntawm tus txheej txheem. Tsuas yog cov thawed carbon fiber prepreg yuav muaj ib qho viscosity, thiab qhov tsim nyog viscosity yog qhov tseem ceeb cuam tshuam rau kev tso tawm ntawm carbon fiber prepreg.

Fiberglass raj yog ib hom yeeb nkab ua los ntawm extrusion nrog thermosetting resin li matrix thiab iav fiber ntau raws li cov khoom siv ntxiv. Fiberglass raj muaj qhov zoo xws li corrosion kuj, kev sib txhuam tsis kam, siab zog, rwb thaiv tsev, anti-static, thiab tsis tshua muaj kev sib txhuam. Vim hais tias cov resin matrix siv feem ntau yog epoxy resin, qhov kub tsis kam yog feem ntau siab, thiab nws feem ntau siv nyob rau hauv qhov kub ntawm -40 degree mus rau 150 degree .

Ntxiv nrog rau epoxy resin, muaj lwm cov resins nrog kev ua tau zoo dua los xaiv los ntawm, thiab cov kav dej fiberglass tseem yuav muaj kev ua tau zoo dua, nrog kev txhim kho qhov kub thiab txias, ncav cuag 180 degree. Fiberglass raj tau dav siv hauv kev lag luam hluav taws xob thiab hluav taws xob engineering, thiab tuaj yeem ua lub luag haujlwm hauv kev txo lossis tiv thaiv cov teeb liab.

Dab tsi yog carbon fiber tube?

Carbon fiber tube yog cov yeeb nkab ua los ntawm pre impregnating carbon fiber nrog resin thiab ces extruding los yog winding nws, ntawm cov kev ua tau zoo ntawm winding yog zoo dua. Carbon fiber extruded kav tsis muaj grooves rau sab nrauv, thaum carbon fiber qhwv cov kav dej tuaj yeem muab faib ua cov kab txaij thiab kab pheeb ces kaum, qhov sib txawv nyob rau hauv txoj kev sib txawv winding.
