Cov kws tshawb fawb Lavxias tau tawm tswv yim siv cov fiber basalt ua cov khoom siv txhawb nqa rau cov khoom siv hauv lub dav hlau. Cov qauv siv cov khoom sib xyaw no muaj peev xwm thauj khoom zoo thiab tuaj yeem tiv taus qhov sib txawv ntawm qhov kub thiab txias. Tsis tas li ntawd, kev siv cov yas basalt yuav txo qhov nqi ntawm cov khoom siv rau sab nraud.
Raws li ib tug xibfwb qhia ntawv qib siab ntawm Department of Economics thiab Industrial Production Management ntawm Perm University of Technology, basalt yas yog cov khoom siv niaj hnub uas ua los ntawm cov pob zeb magmatic thiab cov organic binders. Qhov zoo ntawm basalt fibers piv rau cov iav fibers thiab cov hlau alloys yog lawv cov khoom siv kho tshuab, lub cev, tshuaj lom neeg thiab thermal siab heev. Qhov no tso cai rau cov khaubncaws sab nraud povtseg tsawg dua thaum lub sijhawm ua kom muaj zog, yam tsis ntxiv qhov hnyav rau cov khoom, thiab txo cov nqi tsim khoom rau rockets thiab lwm yam spacecraft.

Cov kws tshawb nrhiav hais tias cov khoom sib xyaw ua ke no siv tau ua cov khoom siv pib rau cov foob pob hluav taws. Nws muaj ntau yam zoo dua li cov khoom siv tam sim no. Lub zog ntawm cov khoom loj tshaj plaws thaum cov fibers raug teeb tsa ntawm 45 ° C. Thaum tus lej ntawm cov txheej txheem yas basalt ntau dua 3 txheej, nws tuaj yeem tiv taus lub zog sab nraud. Ntxiv mus, qhov axial thiab radial displacements ntawm cov kav dej yas basalt yog ob qho kev txiav txim siab qis dua li cov kav dej txhuas sib xws hauv qab tib lub phab ntsa tuab ntawm cov khoom sib xyaw thiab cov hlau txhuas casing.
