Kev Sib Tw Kev Lag Luam
Carbon Fiber Reinforced Polymers (CFRP) ua ib qho kev sib koom ua ke hauv kev lag luam niaj hnub thiab dav hlau (nce txog 50% hauv Boeing 787 thiab 53% hauv Airbus A350). Nyob rau hauv kev caij nkoj loj heev - mus rau - av kub caij tsheb kauj vab (-55℃~ +180 degree), thermal expansion mismatches ntawm cov resin matrix thiab fiber ntau interfaces ua rau muaj kev ntxhov siab nyob rau hauv thermomechanical tseem ceeb. Cov thermal qaug zog feem ntau induces localized interlaminar delamination, matrix cracking, thiab interface debonding. Xws li subsurface micro-kev puas tsuaj, txawm tias thaum tsis tuaj yeem kuaj pom los ntawm kev tshuaj ntsuam pom thawj zaug, tuaj yeem cuam tshuam rau Interlaminar Shear Strength (ILSS) los ntawm ntau dua 30%, ua rau muaj kev pheej hmoo loj heev rau cov qauv kev ncaj ncees.
High-kev ua tau zoo engineering thermoplastics (piv txwv li, PEEK, PEI, PPS, PAI) yog cov khoom tseem ceeb hauv cov cav tov, siab - kub ducting, thiab aviation hluav taws xob sib txuas. Tsis ntev los no raug rau thermal-txheej txheem coupling ib puag ncig (150℃~ 260 degree), cov polymers undergo thermo-oxidative degradation, scission ntawm polymer chains, thiab crosslinking alterations, ua rau muaj kev poob qis hauv tensile zog, flexural modulus, thiab elongation thaum so. Raws li qhov tshwm sim, siab - qhov kub thiab txias nkag mus rau degrades fastener preload, cuam tshuam ib puag ncig sealing thiab cov qauv ntim.
Aerospace tiv thaiv thiab sab nrauv txheej tiv taus siab heev - qhov siab UV hluav taws xob (UVA / UVB siv 5 mus rau 10 npaug siab dua dej hiav txwv), thermal shocks loj heev ntawm kev caij nkoj hauv qab - xoom kub (-60 degree) thiab tarmac tshav kub (+80 degree), nrog rau cov dej ntsev, thiab cov tshuaj tua kab mob 8. marine ntsev pos huab. Environmental degradation- tshwm sim raws li chalking, micro{10}} cracking, poob ntawm adhesion, thiab blistering-compromises nto sealing, exposing lub hauv paus metallic substrates rau localized pitting thiab ua kom lub cev qaug zog.
Kub- ntu ntu, xws li turbine blades thiab combustors, ua haujlwm nyob rau hauv siab - cov roj ntws nrawm tshaj 1000℃. Thermal Barrier Coatings (TBCs)- muaj xws li ib tug ceramic topcoat (xws li, YSZ) thiab ib tug hlau daim ntawv cog lus lub tsho tiv no- feem ntau tsis ua hauj lwm vim oxidation interface, ntau heev buildup ntawm Thermally Grown Oxide (TGO), thiab tom qab spillation induced los ntawm thermal mismatch stresses. High-precision thermal shock thiab siab -kub cyclic oxidation kuaj yog qhov tseem ceeb rau simulate engine davhlau profiles (takeoff-cruise- landing) thiab quantify TBC bond zog thiab spallation resistance.
Nyob rau hauv qhov chaw sov lossis siab tshaj -cov av noo nyob rau hauv marine kev ua haujlwm, cov dej noo nkag mus rau cov qauv sib xyaw ntawm matrix dawb ntim, micro- tawg, thiab fiber ntau / matrix interfaces. Qhov tshwm sim ntawm cov nyhuv plasticization depresses lub matrix iav Transition Temperature (Tg), ua rau muaj teeb meem knockdowns nyob rau hauv siab - kub structural stiffness, Interlaminar Shear Strength (ILSS), thiab compressive zog. Accelerated hygrothermal conditioning los ntsuam xyuas qhov sib npaug ntawm qhov nqus dej thiab Tg hloov yog qhov yuav tsum tau tsim cov khoom tsim uas tso cai rau hauv cov qauv aerospace.
