Taw qhia
Engineers feem ntau sib pivCFC boltsthiabgraphite boltsthaum lawv xaiv fasteners rau lub tshuab nqus tsev vacuum thiab lwm yam siab -kub tshuab. Thaum xub thawj siab ib muag, ob qho tib si cov ntaub ntawv zoo sib xws vim hais tias txhua tus siv carbon- raws li cov qauv. Nyob rau hauv qhov tseeb, lawv coj txawv txawv nyob rau hauv huab cua kub, load, thiab rov qab thermal cycling.
Phau ntawv qhia no piav qhia txog qhov sib txawv tseem ceeb ntawm cov pa roj carbon monoxide (CFC) thiab graphite bolts, vim li cas ntau lub tshuab hluav taws xob hloov mus rau CFC kho vajtse, thiab koj yuav tsum xaiv txoj cai fastener rau koj qhov chaw kub tsim.
Dab tsi ua rau CFC thiab Graphite zoo sib xws?
Ob qho khoom siv los ntawm carbon, thiab ob qho tib si ua haujlwm zoo hauvsiab -kub siv. Vim li no, ntau tus engineers xavgraphitethiabCFC fastenersua ib yam. Tab sis cov qauv sab hauv ntawm txhua yam khoom qhia ib zaj dab neeg sib txawv.
Graphite yog ibmonolithic carbon thaivnrog cov khaubncaws sab nraud povtseg nyob rau hauv ib tug natural crystalline qauv.
CFC yog ibreinforced compositeua los ntawm carbon fibers ua ke nrog ib tug carbon matrix.
Qhov sib txawv no hloov txhua yam:
✔ Muaj zog
✔ Yooj yim
✔ Kev poob siab tsis kam
✔ Xov durability
✔ Kev pab lub neej
Kev nkag siab txog qhov sib txawv no pab engineers xaiv cov khoom zoo dua.
Qhov txawv ntawm cov qauv: Carbon Fiber Reinforcement vs. Ntshiab Graphite
Graphite Bolts: Brittle thiab Rigid
Graphite bolts muab kev ua haujlwm ruaj khov nyob rau hauv siab - qhov kub thiab txias ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv qhov chaw compressive loads.
Txawm li cas los xij, cov khoom siv coj zoo ib yam li ceramics - muaj zog thaum compressed tab sis tsis muaj zog hauv nro lossis shear. Qhov no ua rau muaj kev pheej hmoo siab dua ntawm kev tawg thaum lub sij hawm kho tshuab poob siab, kev co, lossis kev hloov pauv tam sim ntawd.
Cov xov tseem hnav sai dua vim tias graphite tsis muaj cov khoom siv fiber ntau uas yuav tsum tau ua kom rov ua dua los ua kom rov ua dua los yog kho lub voj voog.
CFC Bolts: Muaj zog, tawv, thiab muaj zog
CFC bolts yog tsim los ntawm cov khaubncaws sab nraud povtseg ntawm carbon fibers sib koom ua ke hauv cov pa roj carbon matrix.
Cov qauv sib xyaw no ua kom muaj zog tensile, txhim khu kev yooj yim, thiab muaj kev poob siab zoo dua li monolithic graphite.
Cov xov tuav lawv daim ntawv nyob rau lub sijhawm, txawm tias nyob rau hauv kev rov qab caij tsheb kauj vab lossis kev kub ntxhov siab.
Rau cov tshuab hluav taws xob nrog cov khoom siv hluav taws xob lossis cov cua sov thiab cua txias, CFC bolts xa cov kev pab cuam lub neej ntev dua thiab kev ua tau zoo dua.
