Carbon Fiber Reinforced Carbon Composites (CFCC) muaj ntau yam haujlwm thiab kev siv, feem ntau suav nrog cov khoom siv hluav taws xob, cov khoom siv thermophysical thiab thermal ablation zog.
Mechanical zog
Carbon Fiber Reinforced Carbon Composites muaj lub zog siab thiab zoo heev qaug zog. Nws qhov ceev yog li ntawm 1.7g / cm³, thiab nws ua tau zoo nyob rau hauv cov qauv raug kub kub. Nws tseem tuaj yeem khaws cia chav sov lub zog ntawm 2200 degree, thiab muaj kev puas siab puas ntsws toughness thiab creep kuj. Tsis tas li ntawd, kev taw qhia fiber ntau cuam tshuam rau lub zog ntawm cov khoom siv. Thaum raug quab yuam, nws qhov kev ntxhov siab- txoj kab nkhaus qhia tau tias "pseudoplastic effect", uas yog, nws yog linear thaum pib ntawm daim ntawv thov load, thiab tom qab ntawd dhau los ua kev sib raug zoo bilinear. Tom qab unloading thiab reloading, qhov nkhaus tseem linear thiab tuaj yeem ncav cuag qhov qub load.
Thermophysical zog
Carbon Fiber Reinforced Carbon Composites muaj cov thermal expansion coefficients tsawg, muaj peev xwm tshwj xeeb kub thiab thermal conductivity tsawg. Cov yam ntxwv no ua rau nws ua tau zoo nyob rau hauv qhov kub thiab txias ib puag ncig, tuaj yeem khaws ntau lub zog cua sov thiab tiv thaiv thermal shock thiab thermal kev sib txhuam. Cov ntawv thov tshwj xeeb suav nrog cov tshuab hluav taws xob nuclear, cov foob pob hluav taws tsis zoo, cov khoom siv hluav taws xob sib hloov thiab nres discs.
Thermal ablation kev ua tau zoo
Carbon fiber reinforced carbon composite cov ntaub ntawv muaj qhov zoo thermal ablation kev ua tau zoo thiab yog dav siv nyob rau hauv ablative tshav kub tiv thaiv cov ntaub ntawv. Piv txwv li, lawv yog siv nyob rau hauv lub foob pob hluav taws nozzle caj pas hauv ob sab phlu thiab ntev -ntau yam missile lub qhov ntswg cones. Lawv tshem tawm ntau cov cua sov los ntawm ablation ntawm cov khoom nto thiab tiv thaiv kom tsis txhob muaj cua sov los ntawm cov khoom siv.
