Qhov ntev-inch ratio (qhov piv ntawm fiber ntau ntev rau nws txoj kab uas hla, thaum fiber ntau cross-section yog tsis-cim, txoj kab uas hla ntawm qhov sib npaug cross-sectional ncig cheeb tsam yog xaiv) 30 mus rau 100 fibers.
Vim yog txoj kev npaj sib txawv, kev ua haujlwm ntawm cov hlau fiber ntau sib txawv, xws li lub zog tensile ntawm txias-draw steel hlau yog 380-3000MPa, lub zog tensile ntawm txias-dov strip shearing txoj kev yog {{3} }MPa, thiab txoj kev ingot milling yog 700MPa; molten steel condensation Txawm hais tias txoj kev yog 380MPa, nws yog qhov tsim nyog rau kev tsim cov fibers uas tsis muaj cua sov.
Nyias steel hlau nrog ib tug ntev thiab txoj kab uas hla ntxiv rau ntxiv dag zog mortar los yog pob zeb. Feem ntau siv ntev ncaj steel fibers nrog ncig hla ntu muaj qhov ntev ntawm 10-60 mm, ib txoj kab uas hla ntawm 0.2-0.6 mm, thiab qhov sib piv ntawm 30-100 . Txhawm rau ntxiv cov kev sib txuas sib txuas ntawm fibers thiab mortar lossis pob zeb, ntau yam tshwj xeeb zoo li steel fibers tuaj yeem xaiv, thiab lawv cov ntu ntu yog cov duab plaub, zigzag, thiab meniscus; Qhov kawg yog qhov loj los yog hooked, thiab lwm yam. Thaum siv cov hlais tsis yog voj voog
qauv
Thaum cov hlau fiber ntau nyob hauv cov duab, nws txoj kab sib npaug (de) tuaj yeem xam raws li hauv qab no:
qhov twg a yog qhov tseeb hla ntu ntawm cov hlau fiber ntau.
Txhawm rau kom tawg cov hlau fibers sib npaug hauv cov tshuaj khib lossis pob zeb, qhov sib piv ntawm cov fibers tuaj yeem siv los ua ib pob ntawm cov hlau fibers sib txuas ua ke los ntawm cov kua nplaum dej-soluble. Hlau fibers tuaj yeem ua los ntawm txias-draw steel hlau txiav, nyias steel phaj shearing, steel thaiv los yog ingot milling, thiab melting steel duab. Tsawg carbon steel fibers yuav siv tau los tsim steel fiber reinforced qhob siv nyob rau hauv chav tsev kub; stainless hlau fibers yuav tsum tau siv los tsim refractory steel fiber reinforced qhob. Ntxiv qhov tsim nyog ntawm cov hlau fiber ntau rau mortar lossis pob zeb tuaj yeem txhim kho nws lub zog tensile thiab flexural, thiab txhim kho nws txoj kev tiv thaiv thiab kev cuam tshuam lub zog.
