Polyether ether ketone (abbreviated li PEEK) yog ib qho khoom siv tshwj xeeb polymer nrog ob qho toughness thiab rigidity. Nws qhov kev ua tau zoo ntawm lub qhov dej ntawm lub cev, kev tiv thaiv kev qias neeg, kev sib luag, kev chim siab, nplaim hluav taws, thiab lwm yam zoo dua. . Thaum twg, thaum siv cov roj carbon fiber ntau los ua khoom siv, nws cov khoom siv dag zog, nws lubricating, thiab qaug zog kuj muaj tag nrho cov neeg ua haujlwm, thiab ua rau muaj kev sib tw ua kom yooj yim rau kev sib txig sib luag. Seev thiab lwm yam kev ua si yog kev nyiam.
Tam sim no, Tuam Tshoj lub carbon fiber reinforced polyether ether ketone composite manufacturing tshuab tseem nyob hauv cov luv luv txiav cov fiber ntau los yog cov roj fiber reinforced theem, feem coob ntawm cov roj carbon fiber ntau reinforced polyether ether ketone composites tseem khi rau txawv teb chaws tuaj, Xiamen LFT Composite Plastic Raws li kev tshawb nrhiav thiab kev tsim cov khoom siv hluav taws xob, Cheeb Tsam, tuam txhab muaj ntau heev ntawm cov ntaub ntawv siv technology rau carbon fiber reinforced composite cov ntaub ntawv thiab ua ib tug thawj coj ntawm kev lag luam rau cov pa roj carbon fiber ntau dua . Ntev carbon fiber reinforced polyether ether ketone txhuam board tsim kev, sib qhia thiab tshawb cov txheej txheem tsim ntawm cov roj carbon fiber ntau zog kom tiav cov hluav taws xob polyether ether ketone composite qhov kev ua tau zoo:
Cov nyhuv ntawm Moulding Kub ntawm Cov Khoom Sib Ntsev Cov Khoom Siv Cov Khoom Siv Uas Siv Cov Khoom Siv Uas Siv Cov Khoom Siv Uas Muaj Cov Khoom Uas Muaj Nqa Cov Peeb Zoom
Cov khoom siv dag zog ntawm cov khoom siv ntev ntawm cov roj carbon fiber-reinforced polyethereterketone nce ua ntej thiab ces pib nrog nce molding kub. Feem ntau, cov khoom siv dag zog yuav ncav cuag qhov siab tshaj plaws ntawm qhov kub thiab txias ntawm 370 ° C. Thaum lub ntsuas kub tsawg tsawg, yuav muaj teeb meem ntawm cov tawv nqaij tsis muaj pob txha thiab tsis muab cov khoom faib tawm hauv qhov prepreg. Yog tias cov pob tshuaj tsis muaj zog, cov fibers hauv qhov prepreg yuav tsis sib xyaw kom haum, thiab cov fibers yuav nqus hauv zos thiab cov tshuaj yuav ua kom zoo dua. Thaum twg cov ntaub ntawv phom yog nyuab siab, nws yooj yim los tsim kev nyuab siab concentration, uas cuam tshuam rau tag nrho kev ua tau zoo ntawm lub phaj.
Thaum qhov ntsuas kub ua tau zoo dua, lub cev ntawm lub pob tshuaj yuav zoo dua tuaj, kev sib xyaw kom zoo dua yuav ua rau cov roj carbon fiber ntau dua, kev faib rau hauv cov khoom txheej thiab cov interlayer ua ntau dua, thiab cov ntawv phaj khoom sib xyaw yog nyob hauv kev ntxhov siab. Qhov kev nyuab siab yuav zoo dua pauv los ntawm cov khoom siv mus rau carbon fiber ntau los ntawm qhov interface, uas tsis txhob muaj kev nyuaj siab concentration. Tshaj ntawd, polyethereterketone resin yuav tsim kev sib txuas ntawm kev kub siab, qis theem ntawm kev sib tsoo yuav pab txhim khu lub zog, tab sis thaum kub kub, qhov kev sib txuas ntawm thermal no yuav txo qhov kev ua haujlwm ntawm lub pob zeb Cov tshuaj tiv thaiv yog loj heev. Tshaj kub heev kuj tseem tuaj yeem ua rau lub viscosity ntawm lub pob cwj pwm, ua rau nws tsis muaj kua thiab cuam tshuam rau cov fibers los ntawm qhov zoo impregnated. Vim li no, kev tswj kom sov yog ib qho tseem ceeb tshaj plaws rau kev ua tiav cov kev ua tau zoo tshaj plaws ntawm cov roj fiber reinforced polyether ether ketone composite board.
Cov nyhuv ntawm carbon fiber cov ntsiab lus ntawm cov khoom ntawm cov roj fiber ntau zog siv cov hluav taws xob polyether ether ketone composite:
Raws li cov ntaub ntawv qhia txog kev xeem ntawv xeem tau los ntawm Xiamen LFT Composite Plastic Co., Ltd., kev sib tw ua haujlwm thiab kev sib tshuam hauv kev sib tshuam ntawm cov kev siv cov roj carbon fiber ntau ntawm cov hluav taws xob kom muaj zog tuaj raws li cov pa roj carbon ntau. Nws qhia tau hais tias lub pob zeb ntawm cov khoom siv fiber ntau ntawm polyethereterketone yog qhov ncaj thiab pom meej, tab sis qhov no tsis txhais tau hais tias ntau dua cov pa roj carbon fiber ntau, zoo dua.
Thaum cov roj cov ntsiab lus tsis tshua muaj, lub pob zeb yuav tuaj yeem ua rau cov ciaj si zoo thiab qhov ua tau zoo dua tuaj yeem tsim los ntawm ob. Thaum cov ntaub ntawv phaj siab raug cuam tshuam los ntawm ib qho kev quab yuam sab nraud, txoj hlab pas yuav muaj peev xwm kis tau yooj yim rau cov roj carbon. Lub siab dua cov ntsiab lus, qhov ntau dua qhov khoom thauj uas tag nrho cov tsav nkoj tuaj yeem tiv thaiv tau. Txawm li cas los xij, yog tias cov ntsiab lus carbon fiber ntau dhau lawm, qhov kev faib ua feem ntawm cov ntaub ntawv yuav raug txo kom tsawg, me ntsis reis yuav cuam tshuam rau cov nyhuv ntawm impregnation, nws yuav ua rau cov roj carbon, uas yuav ua rau muaj kev nyuab siab concentration, mechanical properties of composite cov ntaub ntawv. Tib lub sij hawm, ntau ob peb lub cev yuav qhia tau qee cov pa roj carbon uas tsis muaj qhov infiltrated. Cov duab uas tsis sib npaug kuj tseem tuaj yeem cuam tshuam rau lub zog ntawm qhov ob. Thaum cov kab xev nplaum raug txo, lub phaj cais yuav raug tsim delamination. Kev ua haujlwm ntawm kev ua haujlwm ntawm cov txheej txheem tsis zoo. Yog li no, cov ntsiab lus carbon fiber ntau kuj txiav txim xyuas cov kev ua haujlwm ntawm cov kev txiav ntev ntawm cov roj fiber reinforced polyether ether ketone composite board.
Cov nyhuv ntawm qhov txias npaum li cas ntawm Cov Khoom Siv Cov Khoom Siv Uas Muaj Cov Khoom Uas Muaj Cov Khoom Uas Muaj Cov Khoom Uas Muaj Cov P PAJ Zog
Nyob rau hauv cov txheej txheem ntawm cov roj fiber reinforced polyether ether ketone composite board, tsis tsuas yog qhov kub muaj qhov ncaj qha rau lub peev xwm ntawm lub rooj tsavxwm, tab sis tseem qhov txias ceev muaj lub zog zoo tshaj rau cov kev ua haujlwm ntawm cov roj fiber ntau dua li cov hluav taws xob polyether ether ketone. Thaum twg txias txias, polyethereterketone crystallizes sufficiently, thiab spherulites loj yog yooj yim ua. Thaum txias ceev ceev, txoj kev tawm ntawm lub tsho qhov chaw ntawm lub tsho me ntsis yuav poob qab rau qhov kev hloov ntawm qhov kub hloov, uas ua rau tsis sib npaug crystallization ntawm lub polymer. Internal stress yog nws tshwm sim rau hauv cov khoom. Nyob rau tib lub sij hawm, raws li qhov txias txias nce, lub sij hawm crystallization ntawm lub polymer yuav luv, lub crystallinity decreases, tus brittleness ntawm cov ntaub ntawv puas daim ntawv txo, lub toughness tsub kom, tus bending kev kawm thiab interlayer shearing degree txo, thiab cov thais kev ua tau zoo zog. Txoj cai no muab ib daim ntawv qhia txog kev siv cov roj carbon fiber ntau zog kom muaj kev sib tham nrog polyether ether ketone nrog cov ntawv thov txawv. Nws tuaj yeem hloov kho raws li qhov kev xav tau ntawm pawg thawj coj saib kev ua haujlwm.
