Kumvetsetsa CFRP Composites

- Mphamvu Zodabwitsa za Carbon Fiber Reinforced Polymers.

Carbon FiberReinforced Polymer Composites (CFRP) ndi zinthu zopepuka, zolimba zomwe zimagwiritsidwa ntchito popanga zinthu zambiri zomwe zimagwiritsidwa ntchito pamoyo wathu watsiku ndi tsiku. Ndi mawu omwe amagwiritsidwa ntchito kutanthauza fiber-reinforcedzinthu zophatikizayomwe imagwiritsa ntchito mpweya wa carbon monga gawo loyambirira la zomangamanga. Dziwani kuti "P" mu CFRP imathanso kuyimira "pulasitiki" m'malo mwa "polima."

Nthawi zambiri, CFRP composites ntchito thermosetting resins monga epoxy,polyester, kapena vinyl ester. Ngakhalethermoplastic resinsamagwiritsidwa ntchito mu CFRP Composites, "Carbon Fiber Reinforced Thermoplastic Composites" nthawi zambiri amapita ndi mawu awoawo, CFRTP composites.

Mukamagwira ntchito ndi ma kompositi kapena m'makampani ophatikizika, ndikofunikira kumvetsetsa mawu ndi ma acronyms. Chofunika kwambiri, ndikofunikira kumvetsetsakatundu wa FRP kompositindi kuthekera kwamitundu yosiyanasiyana monga kaboni fiber.

Katundu wa CFRP Composites

Zida zophatikizika, zolimbikitsidwa ndi kaboni fiber, ndizosiyana ndi zida zina za FRP zomwe zimagwiritsa ntchito zida zachikhalidwe monga fiberglass kapenafiber aramid. Makhalidwe a CFRP composites omwe ali opindulitsa ndi awa:

Kulemera Kwambiri:A mwambofiberglass yowonjezeredwa ndi kompositikugwiritsa ntchito magalasi osalekeza okhala ndi ulusi wa galasi 70% (kulemera kwa galasi / kulemera kwathunthu), nthawi zambiri kumakhala ndi kachulukidwe ka .065 pounds pa kiyubiki inchi.

Pakadali pano, gulu la CFRP, lomwe lili ndi kulemera kwake kwa 70% komweko, litha kukhala ndi kachulukidwe ka mapaundi .055 pa inchi imodzi.

Mphamvu Zowonjezera:Sikuti ma composites a carbon fiber ndi opepuka, komanso ma CFRP omwe ali amphamvu komanso olimba pagawo lililonse la kulemera kwake. Izi ndi zoona poyerekezera zinthu za carbon fiber ndi galasi fiber, koma makamaka poyerekeza ndi zitsulo.

Mwachitsanzo, lamulo labwino la chala chachikulu poyerekeza chitsulo ndi CFRP composites ndikuti mawonekedwe a carbon fiber amphamvu yofanana nthawi zambiri amalemera 1/5th ya chitsulo. Mutha kulingalira chifukwa chake makampani amagalimoto akufufuza pogwiritsa ntchito kaboni fiber m'malo mwachitsulo.

Poyerekeza zitsulo za CFRP ndi aluminiyamu, imodzi mwazitsulo zopepuka kwambiri zomwe zimagwiritsidwa ntchito, lingaliro lodziwika ndilokuti kapangidwe ka aluminiyamu kamphamvu kofanana kakhoza kulemera nthawi 1.5 kuposa kapangidwe ka kaboni fiber.

Inde, pali zosintha zambiri zomwe zingasinthe kufananitsa uku. Kalasi ndi khalidwe la zipangizo akhoza kukhala osiyana, ndipo ndi kompositi, ndikupanga ndondomeko, kapangidwe ka fiber, komanso mtundu wake uyenera kuganiziridwa.

Zoyipa za CFRP Composites

Mtengo:Ngakhale zinthu zodabwitsa, pali chifukwa chomwe mpweya wa kaboni sugwiritsidwa ntchito pakugwiritsa ntchito kulikonse. Pakadali pano, zophatikiza za CFRP ndizotsika mtengo nthawi zambiri. Malingana ndi momwe msika uliri panopa (kugulitsa ndi kufunidwa), mtundu wa carbon fiber (mlengalenga vs. kalasi yamalonda), ndi kukula kwa fiber tow, mtengo wa carbon fiber ukhoza kusiyana kwambiri.

Mpweya wa carbon waiwisi pamtengo wa paundi paundi ukhoza kukhala paliponse pakati pa 5-nthawi 25-okwera mtengo kuposa fiberglass. Kusiyanitsa kumeneku kumakhala kokulirapo poyerekeza zitsulo ndi zida za CFRP.

Conductivity:Izi zitha kukhala zabwino zonse pazophatikizira za kaboni fiber, kapena choyipa kutengera kugwiritsa ntchito. Mpweya wa carbon ndi wochititsa chidwi kwambiri, pamene ulusi wagalasi umateteza. Ambirintchito ntchito galasi CHIKWANGWANI, ndipo sangathe kugwiritsa ntchito carbon fiber kapena zitsulo, makamaka chifukwa cha conductivity.

Mwachitsanzo, m'makampani othandizira, zinthu zambiri zimafunikira kugwiritsa ntchito ulusi wagalasi. Ichinso ndi chimodzi mwazifukwa zomwe makwerero amagwiritsa ntchito ulusi wagalasi ngati njanji zamakwerero. Ngati makwerero a fiberglass angakhudze chingwe chamagetsi, mwayi wa electrocution ndi wotsika kwambiri. Izi sizingakhale choncho ndi makwerero a CFRP.

Ngakhale mtengo wamagulu a CFRP ukadali wokwera, kupita patsogolo kwaukadaulo kwatsopano pakupanga kukupitilira kulola kuti pakhale zinthu zotsika mtengo. Tikukhulupirira, m'moyo wathu, tidzatha kuwona fiber ya carbon fiber yotsika mtengo yomwe imagwiritsidwa ntchito pazinthu zosiyanasiyana za ogula, mafakitale, ndi magalimoto.
