Nyob rau hauv cov ntaub ntawv puas, carbon fiber yog siv los ua ib lub cev thiab siv pob zeb siv los ua ib hom ntawv. High-performance carbon fiber composites yeej ib txwm siv lub thermosetting rein system, uas yog zoo rau kev ua kom pom tseeb cov khoom sib xws ntawm carbon fiber.
Tab sis tib lub sij hawm, nws muaj nrog ntau yam teeb meem, xws li teeb meem hauv txoj kev ua, lub sij hawm ntev ntev, khoom tsis zoo, kev ua kom tsis muaj zog, thiab khib nyiab pov tseg. Muab piv nrog thermosetting resins, thermoplastic resins yog yooj yim dua tos kom composites siab toughness, thaum tau yooj yim pwm thiab ceev ceev. Yog tsis muaj cov khoom me me ntawm cov txheej txheem molding, uas ua kom txo cov nqi ntau lawm thiab tsim kom muaj ntau ntau.
Txij thaum pib ntawm lub xyoo pua 21st, kev siv cov khoom siv roj carbon fiber ntau hauv cov chaw ua haujlwm tau nce, thiab ntau cov kev cai tau raug muab tso rau tom hauv ntej rau qhov loj, qhov zoo nkauj, thiab siv cov khoom siv sib xyaw. Yog li ntawd, txoj kev loj hlob thiab kev siv cov roj fiber ntau dua tshiab cov khoom siv thermoplastic tau raug tsim tawm sai sai.
Muaj ntau cov thermoplastic resins uas yuav siv rau cov tshuaj substrate, uas yog polyethylene (PE), polypropylene (PP) cov roj polyester, nylon (nylon), polycarbonate (PC), polyphenylene sulfide (PPS), Polyetherimide (PEI), polyethereterketone (PEEK), thiab cov zoo li no. Lawv muab faib ua peb pawg raws li lub cev nqaij daim tawv thiab siv cov yam ntxwv ntawm cov resins sib txawv:
1. Super engineering plastics: high-performance thermoplastics xws li PEEK, PEI, PPS, thiab lwm yam. Cov resins no muaj cov cua kub zoo, siab melting point, thiab siv ntev ntawm 150 degrees los yog ntau dua.
2, engineering plastics: Hom tshuaj siv no yuav tsum ua kom tau raws li qhov kev siv engineering, tsis muaj kev siv tshwj xeeb siv raws li kev tshwj xeeb, muaj kev kub hnyav thiab mechanical zog, xws li PA6, PA66, PET, PBT, ABS.
3. Cov khoom siv dav dav dav dav: cov khoom siv dav dav uas tsis muaj cov khoom kub hnyiab, nqi tsawg, yooj yim molding, thiab noj loj, xws li PP thiab PMMA. Ua ib daim duab ntawm cov khoom siv fiber ntau, xws li cov ntaub ntawv tseem nyob hauv kev loj hlob thiab tseem tsis tau siv ntau qhov ntau.
Ntxiv nrog rau peb pawg no, muaj qee cov ntaub ntawv tshiab nrog kev tiv thaiv tshav kub thiab tej yam khoom siv xws li benzocyclobutene re (BCB) thiab condensed polycyclic polynuclear aromatic hydrocarbon cob (COPNA).
