Faeba e tsoelang pele ea basalt ha e na matla a phahameng feela empa e boetse e na le thepa e ntle haholo joalo ka ho kenya motlakase, ho hanyetsa mafome, le ho hanyetsa mocheso o phahameng. Ho feta moo, ts'ebetso ea eona ea tlhahiso e hlahisa litšila tse fokolang le tšilafalo ea tikoloho, 'me sehlahisoa se lahliloeng se ka senyeha ka tlhaho ntle le kotsi, e leng se etsang hore e be thepa e tala le e mosa tikolohong. Chaena e thathamisitse faeba ea basalt e le e 'ngoe ea likhoele tse' nè tsa bohlokoa bakeng sa nts'etsopele (hammoho le faeba ea carbon, aramid, le polyethylene e boima ba limolek'hule bo phahameng haholo) 'me e fihletse tlhahiso ea indasteri. Faeba e tsoelang pele ea basalt joale e sebelisoa haholo metsoakong e matlafalitsoeng ke faeba, thepa ea khohlano, kaho ea likepe, indasteri ea likoloi, le lits'ebetsong tsa mocheso o phahameng le tse sireletsang.

1. Lisebelisoa tse Tala tse Ngata

   Faeba ea basalt e entsoe ka lefika la basalt, le fumanoang ka bongata bo boholo Lefatšeng le khoeling. Sena se boloka litšenyehelo tsa thepa e tala li le tlase haholo.

2. Lintho tse Sireletsang Tikoloho

   Basalt Lefika ke thepa ea tlhaho. Ts'ebetso ea eona ea tlhahiso ha e ntše boron kapa li-oxide tse ling tsa tšepe tsa alkali, kahoo lerōle le mosi ha li na lintho tse kotsi ebile ha li silafatse sepakapaka. Sehlahisoa sena se boetse se phela nako e telele, e leng se etsang hore e be thepa e ncha e tala e theko e tlase, e sebetsang hantle le e hloekileng.

3. Mocheso o Phahameng le Khanyetso ea Metsi

   Tsoela pele faeba ea basalt e ka sebetsa mochesong o pharaletseng oa -269°C ho isa ho 700°C (ka ntlha ea ho nolofatsa ea 960°C). Sena se phahametse gfaeba ea lass (-60°C ho isa ho 450°C) le faeba ya khabone (max 500°C). Haholo-holo, faeba ya basalt e boloka 80% ya matla a yona a pele ka mora ho sebetsa ho 600°C mme ha e fokotsehe ho 860°C. E boetse e boloka matla a phahameng ka mora ho pepesehela metsi a chesang a 70°C.

4. Botsitso bo Botle ba Lik'hemik'hale le Khanyetso ea ho Sila

   Faeba ea Basalt e na le likarolo tse kang K₂O, MgO, le TiO₂, tse ntlafatsang haholo khanyetso ea eona khahlanong le mafome a lik'hemik'hale le metsi. E tsitsitse haholoanyane ka lik'hemik'hale ho feta faeba ea khalase, haholo-holo libakeng tsa alkaline le asiti. Faeba ea Basalt e bontša khanyetso e betere le ho feta khahlanong le mafome a alkali ka har'a litharollo tsa Ca(OH)₂ tse tletseng le samente.

5. Modulus e Phahameng ea Elastic le Matla a Tensile

   Modulus ea elastic ea fiber ea Basalt (9100-11000 kg/mm) e phahame ho feta ea fiber ea E-glass, asbestos, aramid, polypropylene le silicon. Matla a eona a ho tensile (3800-4800 MPa) a maholo ho feta a fiber ea carbon e hulang haholo, aramid, fiber ea PBI, fiber ea tšepe, fiber ea boron, le fiber ea alumina, 'me e bapisoa le fiber ea S-glass. Ka bongata ba 2.65-3.00 g/cm³ le boima ba Mohs ba 5-9, e fana ka khanyetso e ntle ea ho tsofala le matlafatso ea ho tensile. Matla a eona a mechini a feta haholo likhoele tsa tlhaho le tsa maiketsetso, e leng se etsang hore e be thepa e ntle ea ho matlafatsa.

6. Tshebetso e Ikhethang ea ho Sireletsa Molumo

   Faeba ya basalt e tswelang pele e na le thepa e ntle ya ho monya modumo le lerata. Palo ya yona ya ho monya modumo e eketseha haholo ka makgetlo. Mohlala, thepa e monyang modumo e entsweng ka difaeba tsa basalt tse bophara ba 1-3 μm (tse nang le boima ba 15 kg/m³ le botenya ba 30 mm) e na le di-coefficient tsa ho monya modumo tsa 0.05-0.15 ho 100-300 Hz, 0.22-0.75 ho 400-900 Hz, le 0.85-0.93 ho 1200-7000 Hz.

7. Matlotlo a hlahelletseng a Dielectric

   Faeba ea basalt e tsoelang peleHo hanyetsa bophahamo ba modumo ho phahame ho feta faeba ya khalase ya E, e leng se e fang thepa e ntle ya dielectric. Le hoja lefika la basalt le na le di-oxide tse tsamaisang motlakase tse ka bang 0.2%, kalafo e ikgethang ya bokahodimo ka di-agent tsa boholo bo ka fokotsa tahlehelo ya dielectric ka 50% ha e bapiswa le faeba ya khalase, mme ho hanyetsa bophahamo ba modumo wa yona le hona ho phahame.

8. Ho lumellana ha Silicate ea Tlhaho

   E hasana hantle mme e hokahane ka matla le samente le konkreite. Katoloso ea eona ea mocheso le li-coefficients tsa eona lia tsitsisa, 'me e na le khanyetso e ntle ea boemo ba leholimo.

9. Ho Monya Mongobo o Tlase

   Faeba ea Basalt e na le sekhahla sa ho monya mongobo se ka tlase ho 0.1%, e leng se tlase ho feta faeba ea aramid, ulu ea majoe le asbestos.

10. Ho khanna ha Thermal ho Tlase

    Ho tsamaisa mocheso ha faeba ya basalt ke 0.031-0.038 W/m·K, e leng tlase ho feta faeba ya aramid, faeba ya silicate ya aluminium, faeba ya E-glass, ulu ya lefika, faeba ya silicon, faeba ya carbon, le tshepe e sa ruseng.
