Carbon Fiber Composites: Kugadzirisa Gwaro
Kugadzira kabhoni fiber (CF) macomposites ibhizinesi rine hunyanzvi, tichifunga mainjiniya mazhinji anofunga kugadzira kana kugadzira anobva kumashure kwekugadzira simbi dzesimbi.yakanzi aruminiyamu nhema, uye magadzirirwo ayo uye magadzirirwo ayo akatsanangurwa seatema art.Chii, chaizvoizvo?
Chinangwa chegwaro redhizaini iyi ndechekupa ruzivo rwakajairwa uye zvirevo zvekabhoni fiber inoumbwa zvinhu uye mamwe nhungamiro yekugadzira zvigadzirwa zvisingaremi zvemhando yepamusoro zvine kabhoni fiber composites.
Sei Carbon Fiber
Carbon fiber composites ine yakasarudzika mechaniki zvivakwa zvichienzaniswa nehomogenous simbi nemapurasitiki.Nyaya yacho yakasimba, yakaoma, uye inoreruka.Aya macomposites zvinhu zvesarudzo zvekushandisa uko kukareruka & kwepamusoro kuita kwakakosha, senge zvinhu zvemuchadenga, ndege yekurwira, uye mota dzemujaho.
Chii chinonzi Carbon Fiber Composites
Composite zvinhu zvinogadzirwa nekubatanidza kusimbisa (fiber) nematrix (resin), uye iyi musanganiswa wefiber uye matrix inopa maitiro epamusoro kune chimwe chezvigadzirwa chete.Mune inoumbwa zvinhu, iyo fiber inotakura yakawanda yemutoro uye ndiyo inonyanya kupa muzvinhu zvezvinhu.Iyo resin inobatsira kutamisa mutoro pakati pemafayibha, inodzivirira mafiibhi kubva pakusunga, uye inosunga zvinhu pamwechete.
Yakaita marii?
Nhoroondo, kabhoni fiber kompositi yanga ichidhura zvakanyanya, iyo yakaganhurira kushandiswa kwayo kune yakakosha maapplication chete.Nekudaro, mumakore gumi nemanomwe apfuura, sezvo kushandiswa kwakawedzera uye otomatiki mukugadzira maitiro akawedzera, mutengo wecarbon fiber composites wakadzikira.Iko kusanganiswa kwakaunza pasi mutengo wakazara wezvigadzirwa zvepamusoro zvealuminium.Nhasi, kabhoni fiber composites inogoneka mune zvehupfumi mukushandisa kwakawanda senge zvinhu zvemitambo, mabhoti ekuita, mota dzekuita, uye epamusoro-inoshanda maindasitiri muchina.
Applications
Composite zvinhu zvakasiyana zvakanyanya.Injiniya inogona kusarudza kubva kwakasiyana siyana mafiber uye resin kuti iwane inodiwa zvinhu zvivakwa.Zvakare, ukobvu hwezvinhu uye faibha yekumisikidza inogona kuvandudzwa kune yega yega application.
Zvakanakira zvekabhoni fiber composites ndezvi:
1.Kuomarara kwakanyanya (kuoma kwakapatsanurwa ne density)
2.High chaiyo simba (simba rakakamurwa ne density)
3. Yakanyanya kuderera coefficient yekuwedzera kwekushisa (CTE)
4.X-ray yakajeka (nekuda kwekuderera kwayo kwema molecular uremu)
Ndeapi maapplication anoshandiswa kabhoni fiber kompositi?
Iyo yakasarudzika yekumisikidzwa kwekabhoni fiber inosanganisa ine yakanyanya kusimba simba, kuomarara, uye yakaderera CTE inovapa yakasarudzika nzvimbo munzvimbo zhinji dzekushandisa sezvakaratidzwa patafura pazasi:
Yakajairika mashandisirwo ecarbon fiber composites
Design Information
Carbon Fiber composites inoonekwa se "zvinhu zvemugadziri" nekuti zvikamu zvinogona kugadzirwa kuti zvive nesimba uye kana kuomarara munzira nenzvimbo dzinodiwa.Izvi zvinowanikwa nekuisa zvine hungwaru kuisa zvinhu uye kutungamira fiber kutungamira kuti inyatsoenderana nezvinodiwa.Zvakare, iyo dhizaini uye yekugadzira inoshanduka iyo kabhoni fiber composites inopa inopa mikana yekukwiridzira dhizaini, sekubatanidza uye kubatanidza akawanda maficha mu-situ, kuti uwedzere kudzikisa iyo yakazara chikamu mutengo.
Tooling
Molds inoshandiswa kutsanangura chimiro chezvikamu zvakaumbwa.Iyo inoumbwa chikamu ichatora ese maumbirwo uye maficha ezviumbwa;saka kunaka kwechikamu kunonyanya kukonzerwa nemhando ye mold.Zviumbwa zvinogona kuva murume kana mukadzi.Mold dzechikadzi ndidzo dzakawanda uye dzinoburitsa chikamu chine kunze kwakatsetseka ukuwo chirume chemurume chinoburitsa mukati wakatsetseka.Chiumbwa chakafananidzwa (chirume nechikadzi) chinodiwa kana chikamu chacho chakabatanidzwa uchishandisa muchina.
Zvikamu zviviri zvekushandisa, zvinowanzonzi "clamshell"
Iyo mold inogona kugadzirwa nezvinhu zvakaumbwa, simbi-yakazadzwa epoxy kana kugadzirwa kubva mualuminium kana simbi.Rudzi rwe mold uye zvinhu zvinoshandiswa zvinoenderana nerudzi rwechikamu uye huwandu hwekugadzira.
Manufacturing Process
Yepamberi kabhoni fiber kugadzirwa kazhinji kunoitwa uchishandisa pre-impregnated kabhoni fiber ine thermoset resins.Nzira mbiri dzinokosha dzinoshandiswa ndeidzi:
1. Kugadzika maoko
Kuiswa kwemaoko kwezvinhu zvakarukwa zvisati zvaiswa ichiri chikamu chikuru cheindasitiri yekugadzira inoumbwa, inoda hunyanzvi uye ruzivo rwevashandi vevanhu kuti vagadzire plies dzakatsetseka kuita zvimiro zvakaomarara.Iyo inokwanisa kuburitsa kuita kwepamusoro uye zvikamu zvakaoma asi inogona kuve inodhura uye yakanyanya kuchinjika maitiro.
2. Automated Fiber Placement (AFP)
Zvinhu zvikuru zvekufunga nezvehupamhi hwefiber yauri kushandisa uye compaction roller radius.
