Quartz fiber ntau rau nthwv dej feem ntau suav nrog quartz fiber ntau daim ntaub, quartz fiber siv, quartz fiber ntau tes tsho thiab lwm yam ntaub. Quartz fiber kuj tuaj yeem woven rau hauv peb-dimensional ntaub los ntawm cov txheej txheem weaving tshwj xeeb, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev sib xyaw ua ke thiab kev ua haujlwm ntawm riam phom.
Silica matrix composite reinforced los ntawm quartz fiber ntau muaj permittivity zoo thiab siab transmittance vim nws cov porosity. Silica / SiO2 composite reinforced los ntawm quartz iav fiber ntau tau siv hauv Tebchaws Meskas. As-3dx composite yog tsim nyob rau hauv chav tsev kub thiab 5.8HZ, nrog ε = 2.88 thiab TNA δ = 0.00612. Cov khoom siv tau siv rau Trident submarine missile. Tom qab ntawd, raws li cov khoom siv-3dx, 4D omnidirectional high-purity quartz npuag txhawb nqa silica composite adl-4d6 tau npaj los ntawm inorganic precursor impregnation sintering txoj kev, uas muaj kev ua haujlwm zoo tshaj yoj kis tau tus mob.
Quartz fiber ntau muaj cov khoom siv zoo heev, dielectric, ablative thiab seismic zog. Nws muaj qhov qis thiab ruaj khov dielectric tsis tu ncua thiab cov node poob ntawm qhov siab zaus thiab kub hauv qab 700 ℃, thiab nws lub zog tseem muaj ntau dua 70%. Nws yog ib yam khoom zoo heev multi-functional pob tshab. Lub softening point ntawm quartz iav fiber ntau yog 1700 ℃. Nws muaj cov thermal shock zoo thiab tsis tshua muaj ablation. Nws kuj muaj cov khoom tsis tshua muaj uas cov elastic modulus nce nrog qhov nce ntawm qhov kub thiab txias. Nws kuj yog ib yam khoom tseem ceeb rau kev sib kis yoj dav. Nws tuaj yeem hloov mus rau qhov kub thiab txias ib puag ncig kev hloov pauv tshwm sim los ntawm kev hloov pauv sai sai hauv cov txheej txheem ya davhlau ntawm cov tsheb dav hlau thiab cov cuaj luaj. Nws kuj yog ib qho zoo tagnrho nthwv dej kis khoom siv rau ultra-siab ceev tsheb. Nws yog tsuas yog siv nyob rau hauv lub qhov rais electromagnetic los yog radome ntawm aerospace tsheb thiab missiles. Nws tuaj yeem ua tau raws li qhov nyuaj thiab hloov pauv ib puag ncig ntawm kev kub ceev thiab ultra-high-speed tsheb thiab ua kom lub cev ua haujlwm ntawm kev sib txuas lus, kev taw qhia thiab kev ntsuas qhov ntsuas qhov deb.
