Kev sib piv ntawm qhov ntev / luv iav fiber reinforced PPS composites

PPS puv luv iav fiber ntau (SGF) cov ntaub ntawv sib xyaw muaj qhov zoo ntawm lub zog siab, siab kub tsis kam, nplaim hluav taws, ua haujlwm yooj yim, tsis tshua muaj nqi, thiab lwm yam., hauv tsheb, hluav taws xob, hluav taws xob, tshuab, instrumentation, aviation, aerospace, tub rog thiab lwm cov teb tau ua daim ntawv thov.

PPS puv iav fiber ntau (LGF)Cov ntaub ntawv sib xyaw muaj qhov zoo ntawm kev ua haujlwm siab, tsis tshua muaj kev kub ntxhov, qaug zog ua haujlwm, cov khoom zoo zoo, thiab lwm yam, tuaj yeem siv rau cov dej rhaub dej kub, cov twj tso kua mis, cov pob qij txha, li qub, tshuaj twj tso kua mis impellers thiab vaj tse, dej txias impellers thiab vaj tse, tsev. cov khoom siv.

Yog li dab tsi yog qhov txawv ntawm qhov kev ua tau zoo ntawm luv iav fiber ntau (SGF) thiab iav fiber ntau (LGF) ntxiv dag zog rau PPS composites?

Nyob rau hauv daim ntawv no, cov kev ua tau zoo ntawm PPS / SGF (luv iav fiber ntau) composites thiab PPS / LGF (ntev iav fiber ntau) composites yog muab piv, nyob rau hauv uas PPS / LGF composites yog npaj los ntawm melt impregnation txheej txheem thiab PPS / SGF composites yog npaj los ntawm yaj blending ntxaib-ntsia hlau granulation txheej txheem, yog vim li cas rau siv yaj impregnation txheej txheem yog ua kom tiav cov impregnation fiber bundles nyob rau hauv lub impregnation tuag, thiab cov fiber tsis puas rau cov fibers. Thaum kawg, kev sib piv ntawm cov khoom siv kho tshuab ntawm ob cov ntaub ntawv yuav muab kev txhawb nqa rau kev thov sab ntawm cov kws tshawb fawb hauv kev xaiv cov ntaub ntawv.

Mechanical kev ua tau zoo tsom xam

Cov fibers reinforcing ntxiv rau cov resin matrix tuaj yeem tsim cov pob txha txhawb nqa, thiab thaum cov khoom sib xyaw raug rau sab nraud, cov fibers reinforcing tuaj yeem ua tau zoo ntawm cov khoom siv sab nraud; Nyob rau tib lub sijhawm, lawv tuaj yeem nqus tau lub zog los ntawm kev tawg thiab deformation los txhim kho cov khoom siv kho tshuab ntawm cov resin. Cov duab hauv qab no qhia txog tensile thiab dabtsi yog khoov ntawm PPS / SGF thiab PPS / LGF cov khoom sib xyaw nrog cov iav fiber ntau sib txawv, feem.

Nws tuaj yeem pom tias lub zog tensile thiab dabtsi yog khoov lub zog ntawm cov khoom sib xyaw kom maj mam nce los ntawm kev ntxiv cov iav fiber ntau ntxiv. Qhov laj thawj tseem ceeb yog vim li cas thaum cov iav fiber ntau nce, muaj ntau cov iav fiber ntau hauv cov khoom sib xyaw kom dais lub zog sab nraud, thiab cov resin matrix ntawm cov iav fibers ua thinner vim qhov nce ntawm cov iav fiber ntau, uas yog ntau dua. haum rau kev tsim kho ntawm cov iav fiber reinforced ncej; Yog li ntawd, qhov nce ntawm cov iav fiber ntau ua rau cov khoom sib xyaw ua ke nyob rau hauv daim ntawv thov load, kev ntxhov siab yog ntau dua los ntawm cov resin mus rau iav fibers, uas zoo txhim kho tensile thiab dabtsi yog khoov zog ntawm cov khoom sib xyaw. Lub tensile thiab dabtsi yog khoov zog ntawm cov composite yog zoo txhim kho.

Lub tensile thiab flexural zog ntawm PPS / LGF composites yog siab dua cov PPS / SGF composites. Ntawm 30 feem pua ​​​​ntawm cov iav fiber ntau feem, lub zog tensile ntawm PPS / SGF thiab PPS / LGF cov khoom sib xyaw yog 110 MPa thiab 122 MPa, feem; Lub zog flexural yog 175 MPa thiab 208 MPa, feem; thiab flexural modulus ntawm elasticity yog 8 GPa thiab 9 GPa, feem.

Lub zog tensile, dabtsi yog khoov zog thiab dabtsi yog khoov modulus ntawm elasticity ntawm PPS/LGF composites yog 11. Qhov ntev ntawm cov iav fiber ntau hauv PPS / LGF cov khoom sib xyaw yog siab dua, thiab cov khoom sib xyaw tau zoo dua cov khoom siv thiab cov khoom siv kho tshuab raws li tib lub iav fiber ntau.

Daim duab hauv qab no qhia txog kev cuam tshuam lub zog thiab tsis muaj kev cuam tshuam lub zog ntawm PPS / LGF thiab PPS / SGF cov khoom sib xyaw.

Nws tuaj yeem pom tias qhov cuam tshuam lub zog ntawm cov khoom sib xyaw txo qis ntawm cov iav fiber ntau, feem ntau vim tias cov iav fiber ntau cov ntsiab lus tsis tuaj yeem tsim kom muaj kev ntxhov siab zoo dua hauv kev sib xyaw ua ke, uas ua rau cov iav fiber ntau muaj nyob rau hauv daim ntawv ntawm qhov tsis xws luag thaum sib xyaw. Nws raug cuam tshuam rau kev thauj khoom, ua rau txo qis ntawm qhov cuam tshuam tag nrho ntawm cov khoom sib xyaw.

Cov teeb meem saum toj no yog cov lus qhia iav fiber ntau lossis cov lus qhia tawg; qhov tsis ua hauj lwm ntawm cov thermoplastic composites yog tshwm sim los ntawm cov iav fiber ntau cov lus qhia los yog cov lus qhia tawg, uas pib kis tau los ntawm qhov no mus txog rau thaum cov khoom sib xyaw puas tsuaj tag. Thaum cov iav fiber ntau me me, cov iav fiber ntau cov ntsiab lus tau nce hauv cov khoom sib xyaw, thiab qhov cuam tshuam kev ua haujlwm yuav raug txo kom tsawg vim tias cov nyhuv ntawm cov iav fiber ntau ntawm qhov tawg ntawm cov khoom sib xyaw yog ntau dua li cov iav. fiber reinforcement.

Nrog rau qhov nce ntawm cov iav fiber ntau, cov iav fiber ntau hauv cov khoom sib xyaw tuaj yeem tsim ib qho kev sib txuas lus zoo, thiab cov nyhuv ntxiv zog yog ntau dua li cov nyhuv ntawm cov iav fiber ntau, uas tuaj yeem hloov cov ntaub ntawv zoo dua rau cov khoom siv fiber ntau hauv qab cov nyhuv ntawm cov iav fiber ntau. thov load, thiab tom qab ntawd txhim kho tag nrho cov kev ua tau zoo ntawm cov khoom sib xyaw. zoo zog cuam tshuam. Qhov cuam tshuam lub zog ntawm PPS / LGF ntawm 30 feem pua ​​​​ntawm cov iav fiber ntau yog 19.4 feem pua ​​​​siab dua li ntawm PPS / SGF, los ntawm 31kJ / m2 txog 37kJ / m2, thiab qhov cuam tshuam lub zog yog 54.5 feem pua ​​​​siab dua (los ntawm 7.7kJ / m2 rau 11.9kJ/m2).
