Lub resin matrix ntawm thermopicastic composites koom nrog dav dav thiab cov kws tshaj lij kev tsim kho kom zoo nkauj uas muaj kev tiv thaiv tshwj xeeb, feem ntau yog hu ua "yas tau hu ua" yas tau hu Cov txiaj ntsig kev ua tau zoo suav nrog kev ua kom sov hauv qab no: Cov khoom siv zoo heev, corrosion refamtance, thiab tus kheej-flammability txog rau ul94 v-0 theem. Vim tias pps tau txais cov kev ua tau zoo saum toj no, thiab piv nrog lwm yam kev ua haujlwm ntawm cov khoom siv uas yooj yim, nws muaj tus nqi resin yooj yim rau kev tsim cov khoom siv.
PPS ntxiv cov fiber ntau iav (SGF) cov khoom siv muaj qhov zoo, nplaim hluav taws xob rov qab, kev ua tau yooj yim, nqi qis, thiab lwm yam.
PPS Ncua Ncej (LGF) Cov Khoom Siv Hluav Taws Xob muaj cov txiaj ntsig zoo, cov khoom siv tsis zoo, cov khoom siv tsis zoo, cov khoom siv txias, cov khoom siv txias, cov khoom siv hauv tsev, thiab lwm yam.
Yog li dab tsi yog qhov sib txawv tshwj xeeb hauv cov yam ntxwv ntawm cov iav luv fiber ntau (SGF) thiab ntev iav fiber ntau (LGF) Raam PPS Composites?
Cov Khoom Siv PPS ntawm PPS / SGF (Luvf (Luv thwj iav fiber) sib xyaw thiab PPS / LGF (ntev iav fiber ntau) composites tau muab piv. Qhov laj thawj yog vim li cas cov txheej txheem impregnation yog siv nyob rau hauv kev npaj ntawm kev hloov kho fiber ntau yog tias cov pwm fiber ntau yog tias cov pwm ntawm Impregnation, thiab cov fiber tsis yog puas. Thaum kawg, los ntawm cov ntaub ntawv sib piv ntawm cov khoom siv cov neeg siv ntawm ob, nws tuaj yeem muab kev txhawb nqa kev siv rau kev siv sab nrauv thiab thev naus laus zis thaum xaiv cov ntaub ntawv.
Cov Cuab Yeej Cuab Yeej Cuab Yeej Cuab
Qhov kev txhawb nqa cov fibers ntxiv rau hauv resin matrix tuaj yeem tsim cov tub ceev xwm txhawb nqa. Thaum cov khoom siv sib xyaw ua ke yog raug rau sab nraud, qhov kev txhawb nqa cov fibers tuaj yeem nqa lub luag haujlwm ntawm kev thauj khoom sab nraud; Nyob rau tib lub sijhawm, nws tuaj yeem nqus lub zog los ntawm pob txha lov, deformation, thiab lwm yam, thiab txhim kho cov khoom siv mechanical ntawm lub resin.
Thaum cov ntsiab lus fiber ntau ntxiv, ntxiv cov iav iav hauv cov khoom siv sib xyaw no yog raug rau sab nraud. Nyob rau tib lub sijhawm, vim tias qhov nce nyob rau hauv tus naj npawb ntawm iav fibers, lub resin matrix ntawm lub khob fibers ua dua tshiab rau kev tsim kho cov iav fiber ntau txhawb cov thav duab; Yog li ntawd, qhov nce ntawm iav fiber cov ntsiab lus ua rau cov khoom siv sib xyaw ua kom muaj kev ntxhov siab ntau dua los ntawm cov khoom siv hluav taws xob, uas txhim kho cov khoom lag luam tensile thiab khoov cov khoom ntawm cov khoom sib xyaw.
Lub tensile thiab Flexural zog ntawm PPS / LGF cov composites yog siab dua li cov pps / SGF cov composites. Thaum qhov pawg feem ntawm cov iav fiber yog 30%, lub zog tensile ntawm PPS / SGF thiab PPS / LGF Composites yog 110MPA thiab 122MPA, ntsig txog; Lub zog hloov tau yooj yim yog 175MPA thiab 208MPA, ntsig txog; Flexural Elastic Moduli yog 8GPA thiab 9GPA, ntsig txog.
Lub zog tensile, Flexural zog elastic modulus ntawm lub pps / LGF Compospeed tau nce 11.0%, feem, piv nrog cov pps / SGF cov composites. Qhov ntev retention tus nqi ntawm cov fiber ntau hauv PPS / LGF Composite cov khoom siv siab dua. Nyob rau hauv tib lub iav fiber ntau cov ntsiab lus, cov khoom siv sib xyaw muaj zog thauj thiab zoo dua cov khoom siv tshuab.
