Likopo tsa Sesole: Ho Sireletsa Bophelo ba Ntoa
Ka lilemo tse mashome, mabotho a sesole a 'nile a batla lisebelisoa tse leka-lekaneng tšireletso le ho tsamaea. Lihlomo tsa khale tsa tšepe, leha li sebetsa, li eketsa boima ba 'mele ho likoloi le basebetsi. Li-ceramics tsa silicon carbide li rarolle bothata bona. Ha li sebelisoa mefuteng e mengata ea lihlomo-hangata li koahetsoe ka thepa e kang polyethylene kapa aluminium - lirafshoa tsa SiC li ipabola ho sitisa le ho qhala matla a likulo, shrapnel le likaroloana tse phatlohang.
Likoloi tsa sejoale-joale tsa sesole, lipoleiti tsa lihlomo tsa 'mele, le litulo tsa helikopta li ntse li kenyelletsa liphanele tsa SiC ceramic. Mohlala, lihelmete tsa ntoa tsa Sesole sa US tsa moloko o latelang li sebelisa li-composite tse thehiloeng ho SiC ho fokotsa boima ba 'mele ha li ntse li boloka tšireletso khahlano le mekoloko ea lithunya. Ka mokhoa o ts'oanang, lisebelisoa tsa lihlomo tse bobebe tsa ceramic bakeng sa likoloi tse hlometseng li ntlafatsa ho tsamaea ntle le ho beha polokeho.
Litloaelo tsa Sechaba: Tšireletseho ka Ntle ho Lebala la Ntoa
