PP sau ntev iav fibe Cov Lus Qhia

10 ~ 25 hli ntev iav fiber ntau puv PP (sau ntawv LGFPP) muaj lub zog ntau dua, txhav, tawv, thaj chaw ruaj khov thiab tsis tshua muaj rog ntau dua li dog dig 4 ~ 7 hli luv iav fiber ntau tiv thaiv PP (ntawv luv GFPP). Tsis tas li ntawd, cov iav fiber ntev siv tam polypropylene cov ntaub ntawv tsis tsim kev nkag siab tseem ceeb txawm tias raug rau qhov kub siab ntawm 100 ° C, thiab muaj zoo dua nkag siab dua li luv luv iav fiber reinforced polypropylene. Ntawm kev txhaj tshuaj moulded khoom, cov iav fiber ntau ntev puv PP yog cuam tshuam los ua tus txheej txheem network. Txawm hais tias tom qab cov polypropylene substrate tau hlawv, lub iav fiber ntau lub network ntev tseem ua rau lub iav fiber pob txha caj dab nrog qee qhov muaj zog, thiab lub iav luv luv fiber feem ntau tsis muaj lub zog tom qab hlawv. Lub cev pob txha. Cov xwm txheej no feem ntau yog tshwm sim los ntawm cov nam piv ntawm cov xov kev sib tw txiav txim siab qhov muaj zog, qhov tseem ceeb ntev ntev = L / D, qhov tseem ceeb ntev mus rau txoj kab uas hla tsawg dua 100 muab tub lim thiab luv luv iav fiber ntau yam tsis muaj qhov cuab lub zog, thiab qhov ntev tseem ceeb rau txoj kab uas hla sib piv yog tsawg dua 100 iav fiber ua si lub luag hauj lwm txhawb zog.

Ntev Fib Ntais Qhov Tsis Zoo Tsis Zoo

Piv nrog rau cov ntaub ntawv hlau thiab cov thermosetting sib xyaw, cov iav fiber ntau ntev PP muaj qhov ceev tsawg thiab tib qho hnyav hnyav tuaj yeem txo 20 ~ 50%. Cov iav ntev ntev siv tam PP tuaj yeem muab cov neeg tsim qauv nrog kev tsim dua yooj yim, xws li cov qauv duab. Cov khoom siv, qhov sib xyaw siv, txuag cov nqi pwm (feem ntau ntev iav fiber ntau yas txhaj mould nqi kwv yees li 20% ntawm tus nqi ntawm cov hlau stamping pwm), txo kev siv zog (siv ntev iav fiber ntau yas zog siv lub zog tsuas yog cov khoom lag luam steel 60 ~ 80%, 35 ~ 50% ntawm cov khoom siv aluminium), ua kom yooj yim cov txheej txheem sib dhos.

Daim Ntawv Thov Khwv

Cov hlua ntev fiber ntau siv cov polypropylene siv hauv dashboard lub cev ncej ntawm lub tsheb, roj teeb lub taub hau, pem taub hau kawg module, tswj lub thawv, lub rooj zaum txhawb nqa ncej, spare qhov chaw, fender, chassis npog, suab nrov muab faib, nram qab lub qhov rooj ncej, thiab lwm yam.

Lub rooj zaum hauv tsheb rov qab: hloov cov thav duab steel ib txwm kom ua tiav 20% poob phaus, tsim kev ywj pheej zoo tshaj plaws thiab kev siv tshuab zoo, nthuav cov chaw zaum, thiab lwm yam.
