Ntev Carbon Fiber 30 PP Composite Dub Xim Rau Txhaj Qib

Hais txog Carbon Fiber

Cov pa roj carbon fiber ntau tuaj yeem txhim kho qhov elastic modulus ntawm polypropylene, tab sis txo lub zog tensile, cuam tshuam lub zog thiab elongation ntawm tawg.

Cov pa roj carbon fiber ntau muaj cov nyhuv heterogeneous nucleation ntawm PP, uas ua rau cov tsis-isothermal crystallization ncov kub thiab qib ntawm PP matrix, thiab txhawb kev tsim cov siv lead ua hom hauv PP matrix. Polypropylene yog ib qho yooj yim rau nucleate thiab crystallize ntawm qhov kawg ntawm carbon fiber seem thaum isothermal crystallization. EPDM-g-MAH thiab SEBS-g-MAH muaj qhov zoo dispersion hauv PP matrix, uas ua rau muaj kev cuam tshuam lub zog thiab elongation thaum tawg ntawm PP. PP / CF cov khoom sib xyaw nrog EPDM-g-MAH thiab SEBS-g-MAH muaj kev cuam tshuam ntau zog thiab elastic modulus.

Qhov sib ntxiv ntawm toughening tus neeg sawv cev hauv PP / CF cov khoom sib xyaw ua rau txo qis ntawm nucleation muaj peev xwm thiab crystallization kev loj hlob ntawm PP matrix. Cov khoom siv lead ua ntawm PP / CF sib xyaw tsis tau hloov pauv los ntawm tus neeg sawv cev toughening. Lub nucleation ntawm carbon fiber tau pom tseeb hauv PP / CF cov khoom sib xyaw, thiab cov spherulites feem ntau loj hlob ze ntawm cov pa roj carbon fiber ntau.

Case

PP plastics suav txog 46.5 feem pua ​​​​ntawm kev siv cov yas siv tsheb. Zhu Furong, Tus Lwm Thawj Coj ntawm Automotive Lightweight Business Department of Sinochem International (Holding) Co., LTD., tau taw qhia tias qhov ceev ntawm kev hloov kho PP tuaj yeem raug txo los ntawm kev txo qhov feem pua ​​​​ntawm talc hmoov, thiab lwm yam, piv nrog cov tsoos PP, qhov hnyav. tuaj yeem txo thiab txhaj tshuaj molding lub sij hawm luv luv.

Cov khoom siv PP uas tsis tshua muaj siv hauv lub bumper, qhov rooj vaj huam sib luag thiab lwm qhov chaw muaj qhov hnyav txo qhov hnyav, tib lub sijhawm, kev ua haujlwm ntawm kev sib txhuam thiab xim zoo dua. Composites ntawm PP thiab carbon los yog iav fiber kuj tseem tuaj yeem hloov cov hlau hauv cov kab hluav taws xob tiv thaiv kev taug kev, kev noj cov khoom noj, thiab cov khoom siv vaj huam sib luag rau lub teeb yuag.

Cov lus nug uas nquag nug

1. Dab tsi yog cov yam ntxwv tseem ceeb thiab qhov zoo ntawm qhov ntev fiber ntau reinforced thermoplastics?

Piv nrog rau cov khoom siv luv luv fiber ntau, cov yam ntxwv tseem ceeb ntawm LFT-G thermoplastic ntev iav fiber ntau thiab cov roj carbon fiber ntev yog cov khoom siv kho tshuab, muaj kev cuam tshuam siab thiab tensile modulus, uas tsim nyog rau qee yam khoom loj lossis cov khoom siv thauj khoom. Nws tuaj yeem ua Kev Txhaj Tshuaj Molding, extrusion ntawm nplooj ntawv, profile kav, thiab lwm yam thiab nws yog kev ua haujlwm yooj yim.

2. Tus nqi ntawm cov khoom siv fiber ntau ntev dua. Nws puas muaj tus nqi rov ua dua tshiab?

Cov khoom siv thermoplastic LFT ntev fiber ntau tuaj yeem siv tau thiab rov siv tau zoo heev.
