Dab tsi yog qhov khoom sib txuas tshiab

Keeb kwm ntawm kev siv cov ntaub ntawv tshiab ua ke tuaj yeem taug mus rau lub sijhawm puag thaum ub. Cov nplaim-txhim kho av nplaum siv los ntawm cov txheej txheem txheej puag thaum ub txog rau tam sim no thiab cov pob zeb ua kom muaj zog uas siv los siv rau ntau pua xyoo yog ob qho sib txuas ntawm cov ntaub ntawv ob. Hauv xyoo 1940, vim muaj kev xav tau ntawm kev lag luam aviation, iav fiber ntau dua plastics (feem ntau hu ua iav fiber tam yas uas) tau tsim, thiab lub npe sau cov khoom siv tau muaj txij li tshwm sim. Tom qab xyoo 1950, muaj lub zog muaj zog thiab cov qauv siv hluav taws xob ntau xws li carbon fiber, graphite fiber thiab boron fiber tau ua tiav zoo. Aramid fibers thiab silicon carbide fibers tau tshwm sim nyob rau xyoo 1970. Cov txheej txheem muaj zog, cov xim loj dua tuaj yeem ua ke nrog cov khoom siv tsis yog xim hlau xws li cov ntxig hluavtaws, cov roj carbon, graphite, ceramics, roj hmab, lossis cov hlau tsis xws li txhuas, magnesium, thiab titanium los ua cov khoom sib xyaw tshwj xeeb.

Lub zog tshwj xeeb ntawm ultra-siab molecular phaus polyethylene fiber nyob rau hauv thawj ntawm ntau yam fibers, tshwj xeeb tshaj yog nws tsis kam mus rau tshuaj lom neeg thiab cov khoom zoo tshaj tawm tsam. Nws kuj muaj qhov zoo siab-zaus sonar permeability thiab seawater corrosion tsis kam. Ntau lub tebchaws tau siv nws los ua high-frequency sonar qhov tseem ceeb rau cov nkoj, uas zoo heev txhim kho qhov kev paub ntawm mine thiab qhov kev tshem tawm ntawm cov nkoj. Nws yog tsim los ntawm Sijia Cov Khoom Tshiab Hauv Suav. Cov ntaub ntawv khoom siv tshiab sawv cev tam rau qib siab hauv Suav teb. Ntxiv rau qhov chaw ua tub rog, ultra-high molecular phaus polyethylene fiber kuj muaj cov ntawv thov dav dav nyob rau hauv kev lag luam tsheb, nkoj tsim, khoom siv kho mob, khoom siv kis las thiab lwm cov teb. Thaum cov paib tawm mus, nws ua rau muaj kev txaus siab thiab nyiam los ntawm cov teb chaws tsim khoom hauv ntiaj teb.
