Ubwino wa magwiridwe antchito apamwamba a zida za carbon fiber composite

Zophatikizika zimatanthawuza mtundu watsopano wazinthu zomwe zimaphatikizidwa kuchokera kuzinthu zosiyanasiyana.Mpweya wa carbon fiber womwe timanena nthawi zambiri ndi zinthu zophatikizika ndipo umatchedwa "golide wakuda" muzinthu zophatikizika.Zida zopangidwa ndi kaboni fiber zimapangidwa ndi kaboni fiber tow ndi matrix.(Zida za matrix monga utomoni, zoumba, zitsulo, ndi zina) zophatikizika, zabwino kwambiri zogwirira ntchito zimapangitsa kuti zikhale zoletsedwa bwino pazinthu zachikhalidwe.Nkhaniyi ifotokoza za ubwino wochita bwino kwambiri wa zida za carbon fiber composite.

1. Kachulukidwe wotsika kwambiri

Kuchuluka kwa carbon E-dimensional composite material ndi otsika kwambiri, kachulukidwe kake ndi pafupifupi 1.5gcm3.Poyerekeza ndi zida zachitsulo, monga chitsulo chokhala ndi 7.8gycm3 ndi aluminium alloy ndi kachulukidwe ka 2.8glcm3, awiriwa atha kupeza kuti zida zophatikizika za kaboni zimakhala ndi kachulukidwe kakang'ono kwambiri, kulemera konse kwazinthu zopangidwa ndi zinthu izi ndi komanso yopepuka kwambiri, ndipo imakhala ndi zotsatira zabwino kwambiri zopepuka m'magawo ambiri, zomwe ndizochita zomwe zida zachitsulo zachikhalidwe zilibe.

⒉ mphamvu kwambiri
Zida zosweka za fiber zimakhala ndi mphamvu zambiri, zomwe zimatha kufika ku mphamvu ya 350OMPa.Poyerekeza ndi chitsulo, mphamvu yamakomedwe yachitsulo ndi 65OMPa, ndipo mphamvu ya aluminiyamu ya alloy ndi 42OMPa.Mwanjira iyi, zitha kupezeka kuti mphamvu yayikulu ya carbon fiber ndi yabwino kwambiri.Mkulu, ukhoza kupanga mphamvu ya mankhwala kuti ikwaniritse zosowa zam'mbuyomu za mankhwala, ngakhale mpweya wa carbon ndi anisotropic, udzakhalabe wapamwamba kwambiri kuposa mphamvu yazitsulo zachitsulo.

3. Good dzimbiri kukana

Mpweya wa carbon fiber uli ndi ubwino wabwino kwambiri wa kukana kwa asidi, kukana kwa alkali ndi kukana kwa okosijeni, zomwe zimapangitsa kuti zinthu za carbon fiber zikhale ndi ubwino wogwiritsa ntchito zachilengedwe zambiri, monga chilengedwe chonyowa kapena zinthu za carbon fiber zomwe nthawi zambiri zimawululidwa panja, osati zosavuta kuchita dzimbiri. kapena dzimbiri zenera, ndi ntchito mkulu kwambiri ntchito.

4. Kukana kwamphamvu kwabwino

Zinthu za carbon fiber zimakhala ndi mphamvu yotsutsa kwambiri.Pambuyo popangidwa kukhala zinthu za carbon fiber, zimakhala ndi zotsatira zabwino kwambiri zikagunda kwambiri.Kuonetsetsa chitetezo cha galimoto, chifukwa mkati mwa mankhwala a carbon fiber ndi carbon filament, yomwe imagwirizanitsidwa bwino kudzera muzitsulo za matrix, kuti mphamvuyo iwonongeke bwino pamene mphamvu ikugwiritsidwa ntchito.

5. Kuchita bwino

Zida za carbon fiber zatengera kusinthasintha kwa ulusi bwino kwambiri, zomwe zimapangitsa kuti zinthu za carbon fiber zopangidwa ndi carbon fiber zikhale ndi mapangidwe abwino kwambiri, ndipo zimatha kupangidwa mosinthasintha malinga ndi zomwe makasitomala amafuna, zomwe zimapangitsa kuti ntchito yonse ikhale yabwino.Ikhoza kukwaniritsa zofunikira, komanso imatha kupanga mapangidwe a interlayer pakati pa mankhwala.Mwachitsanzo, pali mapangidwe oterowo pazida zamankhwala ndi masitima othamanga kwambiri.Kuwonetsera kwa nyenyezi yowala ndikwabwinoko, ndipo ilinso ndi mapangidwe abwino owongolera mphamvu., kotero ndi yabwino kwambiri kugwiritsa ntchito kwenikweni mankhwala.

6. Coefficient yotsika yowonjezera kutentha

Zinthu za carbon fiber zimakhala ndi coefficient yotsika kwambiri yokulitsa matenthedwe, yomwe ilinso ndi ntchito yabwino kwambiri yogwiritsira ntchito zinthu zina za carbon fiber zomwe zimafuna kulondola, monga ma telescope, olamulira olondola, kuphatikizapo Xuan Renwei muzamlengalenga ndi zina.Zogulitsa zimatha kupangitsa kuti ntchitoyo ikhale yabwinoko.
