2.Likarolo le ts'ebeliso ea lihlahisoa tsa rabara
Lihlahisoa tsa rabara li na le litšoaneleho tsa elasticity e phahameng, botsitso bo phahameng, matla a phahameng le khanyetso e phahameng ea ho apara.Modulus ea eona ea elastic e tlase haholo, ke 1-10 MPa feela, 'me deformation ea eona ea elastic e kholo haholo, ho fihla ho 100% ho isa ho 1000%.E na le matla a ho tenyetseha le matla a ho boloka matla.Ho phaella moo, e na le khanyetso e ntle ea ho apara, ho thibela molumo, ho senya le ho pata.Leha ho le joalo, rabara e na le ho hanyetsa mocheso o fokolang le ho hanyetsa serame (e khomarelang mocheso o phahameng, e brittle ha e le tlas'a serame), 'me e tla qhibiliha ka lihlapolli.…
Indastering, rabara e ka sebelisoa ho etsa lithaere, litiiso tse tsitsitseng le tse matla, li-vibration damping le likarolo tse thibelang ho sisinyeha, mabanta a phetiso, mabanta a tsamaisang liphaephe le liphaephe, lithapo, lithapo, lisebelisoa tsa ho kenya motlakase le likarolo tsa mariki.
