Fiber Reinforced Thermoplastic Composites (FRTP)
Fiber-reinforced thermoplastic composite thepa ke karolo ea bohlokoa ea lisebelisoa tse kopantsoeng. Li-resin tse fapaneng tsa thermoplastic li matlafatsoa kalikhoele tsa khalase(GF),likhoele tsa carbon (CF), likhoele tsa aramid (AF) le lisebelisoa tse ling tsa fiber. Lisebelisoa tse tsoetseng pele tsa thermoplastic tse matlafalitsoeng li na le thepa e ntle joalo ka ho tiea ho hoholo, ho hanyetsa kutu le ho hanyetsa mokhathala, mokhoa o bonolo oa ho bopa, potoloho e khuts'oane, sekhahla se phahameng sa tšebeliso ea thepa (ha ho na litšila), 'me ha ho na tlhoko ea ho boloka mocheso o tlase,' me e fetohile lipatlisiso. hotspot indastering ea thepa.
Melemo e tloaelehileng ea ts'ebetso ea FRTP
Thermoplastic composite FRTP e 'nile ea sebelisoa ka lilemo tse mashome. Ha ho bapisoa le metsoako ea thermosetting e kang phenolic resin, urea-formaldehyde resin, epoxy resin le polyurethane, metsoako ea thermoplastic e na le litšobotsi tse khethehileng:
◆Boima bo tlase le matla a phahameng:Boima ba FRTP ke 1.1-1.6g/cm3, e leng 1/5-1/7 feela ea tšepe, 1/3-1/4 e bobebe ho feta thermosetting FRP, 'me e ka fumanoa ka boima ba yuniti e nyane Matla a phahameng a mochini le boemo ba kopo.
◆Tekanyo e kholo ea tokoloho moralong oa ts'ebetso: Thepa ea 'mele, thepa ea lik'hemik'hale, le lisebelisoa tsa mochini tsa FRTP li entsoe ka khetho e nepahetseng ea mefuta ea lihlahisoa tse tala, boholo, mekhoa ea ts'ebetso, litaba tsa fiber le mekhoa ea ho beha. Ho na le lisebelisoa tse ngata, tse bohlokoa ka ho fetisisa li kenyelletsa polyetherketoneketone (PEKK), polyetheretherketone (PEEK), polyphenylene sulfide (PPS), nylon (PA), polyetherimide (PEI), joalo-joalo Ka hona, eona Tekanyo ea tokoloho ea khetho ea thepa le moralo e boetse e kholo ho feta.
◆Thermal properties: Mocheso o akaretsang oa tšebeliso ea polasetiki ke 50-100 ℃, 'me o ka eketsoa ho feta 100 ℃ ka mor'a ho matlafatsoa ka fiber ea khalase. Mocheso oa mocheso oa PA6 ke 65 ° C, 'me ka mor'a ho matlafatsoa ka fiber ea khalase ea 30%, mocheso oa mocheso oa mocheso o ka nyolohela ho 190 ° C. Ho hanyetsa mocheso oa PEEK ho fihla ho 220 ° C. Kamora ho matlafatsoa ka fiber ea khalase ea 30%, mocheso oa ts'ebetso o ka nyolohela ho 310 ° C. Thermosetting composite thepa e ke ke ea finyella ho hanyetsa mocheso o phahameng joalo.
◆Lik'hemik'hale corrosion resistance: Haholo-holo e khethoa ke ts'ebetso ea thepa ea matrix. Ho na le mefuta e mengata ea li-resin tsa thermoplastic, 'me resin ka' ngoe e na le litšobotsi tsa eona tse thibelang ho bola. Ka hona, resin ea matrix e ka khethoa ho latela tikoloho ea ts'ebeliso le maemo a mahareng a thepa e kopaneng. Ka kakaretso, e ka finyella litlhoko tsa tšebeliso. Khanyetso ea metsi ea FRTP le eona e betere ho feta ea li-composite tsa thermosetting.
◆Lintho tsa motlakase: FRTP ka kakaretso e na le thepa e ntle ea dielectric, ha e bontše maqhubu a seea-le-moea, 'me e fetisetsa li-microwave hantle. Kaha sekhahla sa ho monya metsi sa FRTP se nyane ho feta sa thermosetting FRP, thepa ea eona ea motlakase e betere ho feta ea morao-rao. Kamora ho eketsa lisebelisoa tsa conductive ho FRTP, e ka ntlafatsa conductivity ea eona le ho thibela tlhahiso ea motlakase o tsitsitseng.
◆Litšila li ka sebelisoa hape: FRTP e ka sebetsoa bocha le ho etsoa, litšila le tse setseng li ka sebelisoa hape, 'me thepa ea 'mele le ea mochini ha e fetohe haholo, mme e ke ke ea baka tšilafalo ea tikoloho. ditlhoko tsa tikoloho.
