Bambanci tsakanin fiber carbon da karfe.

Daga cikin abubuwa da yawa, abubuwan haɗin fiber carbon (CFRP) an biya su da ƙarin kulawa don ingantaccen takamaiman ƙarfin su, takamaiman taurin kai, juriya da lalata juriya.

Daban -daban halaye tsakanin abubuwan haɗin carbon fiber da kayan ƙarfe suma suna ba injiniyoyi ra'ayoyin ƙira daban -daban.

Mai zuwa zai zama kwatankwacin sauƙi tsakanin abubuwan haɗin carbon fiber da halayen ƙarfe na gargajiya da bambance -bambance.

1. Musamman taurin kai da takamaiman ƙarfi

Idan aka kwatanta da kayan ƙarfe, kayan fiber na carbon suna da nauyi, babban takamaiman ƙarfi, da takamaiman taurin kai. Modulus na fiber carbon-resin ya fi na aluminium, kuma ƙarfin sinadarin carbon-resin ya fi na aluminium ƙarfe.

2. Zane

Kayan ƙarfe galibi duk jinsi ɗaya ne, akwai abin da ake samarwa ko yanayin abin da ke faruwa. Kuma filayen carbon guda ɗaya yana da madaidaiciyar madaidaiciya.

Kayayyakin inji tare da jagorancin fiber sune umarni masu girma na 1 ~ 2 mafi girma fiye da waɗanda ke kan madaidaicin filayen tsaye da kaddarorin a tsaye da na ƙetare, kuma ƙwanƙwasa-matsin lamba na roba ne na roba kafin fashewa.

Sabili da haka, kayan fiber na carbon na iya zaɓar kusurwar shimfiɗa, rabon kwanciya, da kuma shimfidar layin-layi ɗaya ta hanyar ka'idar farantin lamination. Dangane da halayen rarrabuwa na kaya, za a iya samun taurin da ƙarfin aiki ta ƙira, yayin da kayan ƙarfe na gargajiya kawai za a iya yin kauri.

A lokaci guda, ana iya samun kaifin da ake buƙata a cikin jirgi da ƙarfi kazalika da keɓaɓɓen haɗe-haɗen da ke cikin jirgin.

3. Rashin juriya

Idan aka kwatanta da kayan ƙarfe, kayan fiber carbon suna da ƙarfi acid da juriya na alkali. Fiber carbon shine tsarin microcrystalline mai kama da crystal crystal wanda aka kirkira ta hanyar zane-zane a babban zazzabi na 2000-3000 ° C, wanda ke da tsayayyar tsayayyar lalata, har zuwa 50% hydrochloric acid, sulfuric acid ko phosphoric acid, modulus na roba, ƙarfi, kuma diamita ba ya canzawa.

Sabili da haka, azaman kayan ƙarfafawa, fiber carbon yana da isasshen garanti a juriya na lalata, resin matrix daban a juriya na lalata ya bambanta.

Kamar yadda ake amfani da iskar gas mai ƙarfi na carbon, epoxy yana da mafi kyawun juriya na yanayi kuma har yanzu yana riƙe ƙarfinsa da kyau.

4. Anti Gajiya

Matsalar matsewa da babban matakin damuwa sune manyan abubuwan da ke tasiri gajiyar gajiya na abubuwan haɗin fiber carbon. Yawancin kayan gajiya galibi ana yin gwajin gajiya a ƙarƙashin matsin lamba (R = 10) da matsin lamba (r = -1), yayin da kayan ƙarfe ke fuskantar gwajin gajiya mai ƙarfi a ƙarƙashin matsin lamba (R = 0.1). Idan aka kwatanta da sassan ƙarfe, musamman sassan gami na aluminium, sassan fiber carbon suna da kyawawan halaye na gajiya. A fagen chassis na mota da sauransu, abubuwan haɗin fiber carbon suna da fa'idodin aikace -aikacen mafi kyau. A lokaci guda, kusan babu wani sakamako mai daraja a cikin fiber carbon. Kwancen SN na gwajin da aka yi daidai yake da na gwajin da ba a sani ba a cikin rayuwar yawancin laminates na carbon fiber.

5. Saukewa

A halin yanzu, matrix fiber ɗin balagagge an yi shi da resin thermosetting, wanda yana da wahalar cirowa da sake amfani da shi bayan warkewa da haɗin gwiwa. Don haka, wahalar dawo da filayen carbon yana ɗaya daga cikin matsalolin ci gaban masana'antu, haka kuma matsalar fasaha da ke buƙatar warwarewa cikin gaggawa don aikace-aikace mai girma. A halin yanzu, galibin hanyoyin sake sarrafa abubuwa a gida da waje suna da tsada kuma suna da wuyar zama masana’antu. Walter carbon fiber yana aiki da bincike kan hanyoyin da za a iya sake maimaitawa, ya kammala samfura da yawa na samar da gwaji, tasirin murmurewa yana da kyau, tare da yanayin samar da taro.

Kammalawa

Idan aka kwatanta da kayan ƙarfe na gargajiya, kayan fiber na carbon suna da fa'idodi na musamman a cikin kayan aikin injiniya, mara nauyi, ƙira, da juriya na gajiya. Koyaya, ingancin samar da shi da kuma murmurewarsa mai wahala har yanzu shine ƙalubalen ƙarin aikace -aikacen sa. An yi imanin cewa za a yi amfani da filayen carbon da yawa tare da ƙirƙirar fasaha da aiwatarwa.
