Senhengo yakakosha yeminda yechipfupi, Ultra-pfupi-pfupi kabhoni fiber, ine zvivakwa zvaro zvakasarudzika, zvakakonzera kutarisisa kwakapararira muindasitiri akawanda uye minda yehunyanzvi. Iyo inopa chinyorwa chitsva chekugadzirisa kwakanyanya kwezvinhu zvekushandisa, uye nekunzwisisa kwakadzama kwengoro dzaro dzekushandisa uye maitiro kwakakosha kutyaira kuvandudzwa kwesindasitiri ane hukama.

Kazhinji, kureba kweiyo Ultra-pfupi kabhoni mafupi ari pakati pe0,1 - 5mm, uye density yavo yakaderera pa1.7 - 2G / cm³. Nezve yakaderera dentity ye1.7 - 2.2G / cm³, cm³, sosi yegumi nenomwe - 7000mpa yeElasticity ya200 - 700gpa, aya akanakisa manhamba anogadzira hwaro hwekushandisa kwayo mukugadzira-mutoro zvivakwa. Mukuwedzera, iyo ine yakanyanya kupisa kupisa simba, uye inogona kutsungirira kupisa kwakanyanya kweanopfuura 2000 ° C mune isiri-oxidizing mamiriro ekunze.
Chikumbiro chehunyanzvi uye maitiro e Ultra-pfupi carbon fiber muAerospace munda
Mundima yeAerospace, Ultra-pfupi kabhoni fiber inonyanya kushandiswa kusimbisaresinmatrix manyadzo. Iyo kiyi yeTekinoroji ndeyekuita kuti kabhoni fiber yakatwasuka mumugodhi matrix. Semuenzaniso, kutora tekinoroji yekupararira yekupararira zvinokwanisika kuputsa chiitiko cheCarbon fiber Agglomeroration, zvekuti iyo yekupararira inobatanidza inosvika kunopfuura 90%, ichisimbisa hukama hwezvivakwa. Panguva imwecheteyo, kushandiswa kweFiber Surpalatment Tekinoroji, sekushandiswa kweCoupling Mumiririkurapwa, kunogona kuita kuticarbon fiberuye Resin Interface Bond Simba yakawedzera ne30% - 50%.
Mukugadzirwa kwemapapiro emhepo uye zvimwe zvigadzirwa zvemhando, kushandiswa kwekupisa tangi tank maitiro. Chekutanga pane zvese, iyo Ultra-pfupi kabhoni fiber uye resin yakasanganiswa neyakaenzana yakagadzirwa prepreg, yakaiswa muTangi inopisa. Izvo zvinobva zvaporeswa uye kuumbwa pakudziya kwe120 - 180 ° C uye kumanikidzwa kwe0.5 - 1.5mpa. Maitiro aya anogona kuita zvinobudirira mumhepo mabhuru emamhepo mune zvinyorwa zvemukati kuti uve nechokwadi chekusvava uye nekukwira kwakanyanya kwezvigadzirwa.
Tekinoroji uye maitiro ekushandisa kweiyo Ultra-pfupi kabhoni fiber mune iyo automotive indasitiri
Kana uchinyorera Ultra-pfupi carbon fiber kune zvikamu zvemotokari, iyo inotarisisa iri mukuvandudza kuenderana kwayo nezvinhu zvibodzwa. Nekuwedzera chaiyo comatilizilizers, iyo interfcial Adhisheni pakati peCarbon Fibers uye Base zvinhu (semuenzanisoPolypropylene, nezvimwewo) inogona kuwedzerwa ne40%. Panguva imwecheteyo, kuitira kuti uvandudze mashandiro aro munzvimbo dzakaoma dzekushushikana, fiber edzimaniso dhizaini tekinoroji inoshandiswa kugadzirisa nzira yekugadzirisa fiber zvichienderana neyakaoma.
Iyo jekiseni kuumbwa maitiro anowanzo shandiswa mugadziri yezvikamu zvakaita semotokari hood. Ultra-pfupi carbon fils yakasanganiswa nezvikamu zvepurasitiki uye zvobva zvabuda muumbi cavity kuburikidza nekudziya kwakanyanya nekumanikidza. Iyo jekiseni tembiricha kazhinji 200 - 280 ℃, kudzvinyirirwa kwejekisi kuri makumi mashanu - 150 mpa. Maitiro aya anogona kuziva kukurumidza kuumbwa kwezvinhu zvakaoma zvikamu, uye zvinogona kuve nechokwadi chekuparadzirwa yunifomu yekabhoni macaboni mune zvigadzirwa.
Tekinoroji uye maitiro e Ultra-pfupi kabhoni fiber application mugetsi yemagetsi
Mumunda wemagetsi ekupisa kwemagetsi, iyo yekushandiswa kweiyo yekubatira inonhuwirira yeiyo ultra-pfupi kabhoni carbon fibers kiyi. Nekutsvagira degree remafironi reCarbon fiber, yayo inobata nayo inogona kuwedzerwa kune anopfuura 1000w / (mk). Zvichakadaro, kuve nechokwadi chekutaurirana kwacho kwakanaka nezvematongerwo enyika, soursial tekinoroji, yakadai semakemikari nickel plating, inogona kuderedza kupokana kwemasvomhu neanopfuura 80%.
Powder Metallurgy maitiro anogona kushandiswa mukugadzira komputa cpu heatsinks. Iyo Ultra-pfupi carbon fiber yakasanganiswa neesimbi poda (semuenzaniso Copper Powder) uye akatambanudzwa pasi pekupisa kwakanyanya uye kumanikidzwa. Tembiricha yekushisa inowanzoita mazana mashanu - 900 ° C uye kumanikidzwa kuri 20 - 50 mpa. Maitiro aya anogonesa iyo kabhoni fiber kuti iite tsvina yakanaka yekuita chiteshi ne simbi uye inovandudza iyo yekupisa kusarongeka.
Kubva kuEerospace kune indasitiri yemotokari kune zvemagetsi, neicho chinoramba chidzitiro chehunyanzvi uye maitiro ekugadzirisa, Ultra-pfupicarbon fiberichavhenekera muminda yakawanda, kujekesa simba rine simba resainzi yesainzi uye tekinoroji uye kukura kwemaindasitiri.
