Hobaneng ha Carbon Fiber

Li-composite tsa carbon fiber li na le lisebelisoa tse ikhethang ha li bapisoa le litšepe tse tšoanang le lipolasetiki.Thepa e matla, e thata, ebile e bobebe.Likarolo tsena ke lisebelisoa tsa khetho bakeng sa lits'ebetso moo ts'ebetso e bobebe le e phahameng e leng ea bohlokoa, joalo ka likarolo tsa sepakapaka, lifofane tsa ntoa le likoloi tsa mabelo.

Carbon Fiber Composites ke eng

Lisebelisoa tse entsoeng ka motsoako li entsoe ka ho kopanya matlafatso (fiber) le matrix (resin), 'me motsoako ona oa fiber le matrix o fana ka litšobotsi tse phahameng ho feta leha e le efe ea thepa feela.Ka thepa e nang le motsoako, fiber e jara boholo ba mojaro 'me ke eona e kenyang letsoho haholo thepa ea thepa.Resin e thusa ho fetisa mojaro lipakeng tsa likhoele, e thibela likhoele ho thella, 'me e kopanya lisebelisoa.
