Polasetiki e Matlafalitsoeng ea Fiberglass (FRP/GFRP)
* Lihlahisoa tsa fiberglass tse etselitsoeng motho ka mong, tse phuthetsoeng le ho romelloa ho latela litlhoko tsa ho iketsetsa!
* FRP, e tsejoang hape e le Fiber Reinforced Plastic (FRP), ke thepa e kopaneng e entsoeng ka likhoele tsa khalase le resin. E na le thepa e ntle ea mechini le ho hanyetsa mafome, 'me e sebelisoa haholo likepeng, likoloing, kahong, indastering ea lik'hemik'hale, matla a motlakase le masimong a mang.
* Lihlahisoa kapa likarolo tsa polasetiki tsa FRP tse ikhethileng
FRP ke mofuta oa thepa e kopaneng, e entsoeng ka faeba ea khalase le lihlahisoa tsa eona tse kang lesela la khalase, theipi, felt le khoele e le thepa e matlafatsang le resin ea maiketsetso e le thepa ea matrix. Ka lebaka la matla a eona e lekana le tšepe, 'me e na le likarolo tsa khalase, e boetse e na le' mala, sebopeho, ho hanyetsa mafome, ho thibela motlakase, ho thibela mocheso le litšobotsi tse ling tsa khalase, kahoo ka tšoantšetso e bitsoa "polasetiki e matlafalitsoeng ea faeba ea khalase".
FRP e tsebahala ka karolelano ea eona e phahameng ea matla ho ea boima, ho hanyetsa mafome, le ho tšoarella 'me e sebelisoa lits'ebetsong tse fapaneng tse kang indasteri ea likoloi, ea lifofane, ea kaho le ea likepe hammoho le lefapheng la lisebelisoa tsa mekhabiso.
Ke melemo efe eo FRP e fanang ka yona ho feta dipolasetiki tse ding?
Ho eketsa likhoele ho likhoele tsa khalase ho fokotsa boima le ho eketsa modulus ea ho tenyetseha le matla a mechini. Ka lebaka leo, thepa ena e ka sebelisoa ho hlahisa likarolo tse hlokang moralo o nepahetseng, meeli ea mamello e behiloeng esale pele, mokhathala o tlase, khanyetso e phahameng ea tšusumetso le litšobotsi tse ntle tsa khatello. Li ka nolofatsa moralo oa likarolo le ho ntlafatsa tlhahiso le katleho ea ts'ebetso. Li-FRP li boetse li na le litšobotsi tse ntle tsa ho thibela mocheso le molumo 'me li ka mamella tlhaselo ea lik'hemik'hale tse senyang, tšusumetso ea maqhubu, libaka tse mongobo le lifefo/mafefo.

Mokhoa oa tlhahiso ea fiberglass
Ho ya ka dibopeho tsa thepa tsa FRP, mekgwa e ka sehloohong ya tlhahiso e sebediswang hangata e kenyeletsa ho bopa ka ho kobeha, ho bopa ka ho otloloha, ho bopa ka kgatello, le ho bopa ka letsoho.
FRP e na le thepa efe?
* Taba ea pele, boima bo bobebe le matla a phahameng: boima bo lekanyelitsoeng ba FRP bo pakeng tsa 1.5 ~ 2.0, ke 1/4 ~ 1/5 feela ea tšepe ea carbon, empa matla a ho thaepa a haufi kapa a feta a tšepe ea carbon. Matla a itseng a ho thaepa a epoxy FRP, matla a ho bapala le a ho hatella a ka fihla ho feta 400Mpa.
* Ea bobeli, thepa e ntle ea motlakase: FRP ke thepa e ntle ea ho thibela mocheso, e sebelisetsoang ho etsa li-insulator, maqhubu a phahameng a ntse a ka sireletsa thepa e ntle ea dielectric.

Ea boraro, ts'ebetso e ntle ea mocheso: FRP e nang le conductivity e tlase ea mocheso, ke 1/100 ~ 1/1000 feela ea tšepe, ke thepa e ntle ea ho thibela mocheso.
Sa bone, ho ba le moralo o motle: ho latela tlhoko ea ho rala ka mokhoa o tenyetsehang mefuta e fapaneng ea lihlahisoa tsa sebopeho ho fihlela litlhoko tsa ts'ebeliso ea sehlahisoa ho ka etsoa hore ho be le botšepehi bo botle. E ka boela ea khetha thepa ka botlalo ho fihlela ts'ebetso ea sehlahisoa.
Sa bohlano, mosebetsi o motle haholo: ho latela sebopeho sa sehlahisoa, litlhoko tsa tekheniki, ts'ebeliso le palo ea khetho e tenyetsehang ea ts'ebetso ea ho bopa. Ts'ebetso e bonolo, e ka bōptjoa hang-hang, phello ea moruo e ikhetha, haholo-holo bakeng sa sebopeho sa se rarahaneng, ha ho bonolo ho theha palo e nyane ea lihlahisoa, e hlahelletseng haholoanyane ka bophahamo ba eona ba ts'ebetso.
