(1) Qhov kub ntawm cov thermoplastic khoom uas muaj qhov tsawg thiab qhov siab muaj zog yog 1.1 mus rau 1.6 g / cm3, uas tsuas yog 1/5 rau 1/7 ntawm cov khoom siv hlau, thiab yog 1/3 rau 1/4 ntais dua li thermosetting iav hlau. Nws muaj peev xwm ua kom tiav siab dua qub zog nrog rau ib pawg me me. Feem ntau hais lus, seb nws yog hom phiaj yas lossis cov khoom siv hlau, tom qab siv cov iav fiber ntau, nws yuav tau txais kev pabcuam zog dua qub thiab ua kom zoo ntxiv rau qib ntawv.
(2) Kev tsim txoj kev ywj pheej Tsim lub cev nqaij daim tawv , cov khoom siv tshuaj thiab cov khoom siv dag zog ntawm cov thermoplastic composites yog tsim los ntawm kev xaiv ntsej muag ntawm cov khoom siv, cov cim, cov txheej txheem, cov ntsiab lus fiber ntau thiab kev tsim. Vim cov thermoplastic composites muaj ntau cov ntaub ntawv siv ntau tshaj li thermoset composites, cov kev ywj pheej ntawm cov khoom xaiv yog ntau dua.
(3) Thermal Properties Feem ntau, cov yas siv los ntawm qhov kub ntawm 50 txog 100 ° C, thiab tuaj yeem siab txog 100 ° C lossis siab dua tom qab siv cov iav fibers. Lub tshav kub kub ntawm cov nylon 6 yog 65 ° C. Tom qab siv zog nrog 30% iav fiber, qhov sov sov kub kub tau nce mus rau 190 ° C. Kub kub ntawm lub polyethereterketone resin ncav cuag 220 ° C. Tom qab raug kho nrog 30% iav fiber ntau, qhov kub thiab txias yuav nce ntxiv mus rau 310 ° C. Qhov kev kub hnyiab no thiab thermosetting puas khoom tsis tau. Qhov linear expansion coefficient ntawm cov thermoplastic composite khoom yog 1/4 rau 1/2 qis dua li ntawm cov yas uas tsis muaj tiag, uas tuaj yeem txo qhov qis zog thaum lub sij hawm molding txheej txheem ntawm cov khoom thiab txhim kho qhov tseeb ntawm qhov khoom. Nws cov thermal conductivity yog 0.3 txog 0.36 W (m2 • K), zoo ib yam li thermoset composites.
(4) Cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv cov tshuaj tiv thaiv yog qhov txiav txim siab los ntawm cov khoom ntawm cov khoom siv hauv matrix. Muaj ntau ntau hom thermoplastic resins. Txhua lub tshuaj muaj nws tus kheej cov yam ntxwv tawm tsam. Yog li ntawd, nws yuav ua tau raws li qhov chaw thiab nruab nrab ntawm cov ntaub ntawv sib xyaw. Cov xwm txheej, lub hauv paus koog tsev kawm ntawv nyiam, thiab feem ntau ua tau raws li cov kev cai rau kev siv. Cov thermoplastic composites yog superior hauv cov dej tsis haum rau cov thermoset composites.
(5) Cov Khoom Siv Hluav Taws Xob Cov khoom siv thermoplastic muaj cov khoom zoo dielectric, tsis txhob cuam tshuam cov xov tooj cua, thiab muaj kev ua tau zoo microwave. Txij li cov thermoplastic composite muaj dej nqus dej tsawg dua li lub thermosetting iav reinforced yas, nws cov hluav taws xob cov khoom yog superior rau tom kawg. Qhov sib ntxiv ntawm cov khoom siv hluav taws xob rau lub thawv thermoplastic ua rau nws cov hluav taws xob hluav taws xob thiab tiv thaiv cov cim hluav taws xob.
(6) Muab cov khoom siv khib nyiab rov Siv cov khoom siv thermoplastic rov tuaj yeem ua haujlwm thiab tsim tau, thiab cov khoom siv thiab cov khoom siv yuav tawg tuaj yeem siv tau thiab siv tsis muaj kev cuam tshuam kev tsis zoo.
Vim tias thermoplastic composites muaj ntau cov khoom tshwj xeeb zoo tshaj rau cov thawv FRP, daim teb daim ntawv thov yog ntau heev. Los ntawm kev ntsuam xyuas ntawm kev siv txawv teb chaws, thermoplastic composites yog siv nyob rau hauv lub tsheb tsim kev lag luam, electromechanical kev lag luam, tshuaj anti-corrosion thiab engineering engineering.
