Kuita kuenzanisa kwekabhoni fiber chubhu uye girazi fiber chubhu

Carbon fiber chubhu uye girazi fiber pombi maitiro maviri ekushandisa emachubhu anoumbwa.kabhoni fiber chubhu inogadzirwa nemhepo, pultrusion kana mhepo yekabhoni fiber prepreg, ukuwo girazi fiber chubhu inodhonzwa uye inoburitswa negirazi faibha uye resin.Mapombi ezviviri izvi anoshandiswa zvakanyanya muaerospace, kugadzira mota, mitambo uye mamwe maindasitiri.Ndeipi misiyano mukuita kwavo?

Kuwanda kwekabhoni fiber chubhu i1.6g/cm ³, ishoma pane iyo yealuminium alloy, kusimba kwepombi yesimbi 300 ~ 600MPa, simba rekusimba realuminium alloy pombi i110 ~ 136MPa, uye kusimba kwesimba re kabhoni faibha chubhu inenge 1500MPa.Thermal kuwedzera coefficient of carbon fiber composite is-1.4 × 10 ^ -6, iyo inogona kuvimbisa kuti saizi yechigadzirwa yakagadzikana uye haisi nyore kukanganisa.Iyo yekuneta simba muganho wekabhoni fiber chubhu ndeye 70% ~ 80% yesimba rayo rekusimba.Paunenge uchishanda pasi penguva refu yekuchinjisa mutoro, iyo kabhoni fiber chubhu inogadzikana uye ine hupenyu hwesevhisi hurefu.Uye iyo kabhoni fiber zvinhu ine yakanaka magetsi conductivity uye yakanakisa electromagnetic kudzivirira kuita.

Huremu hwegirazi fiber chubhu 2.53 ~ 2.55g/cm ³inorema kupfuura iyo yekabhoni fiber chubhu yezvakafanana, simba rekusimba 100 ~ 300MPa, modulus ye elasticity 7000MPa, elongation pakupwanya 1.554%, chiyero chePoisson 0.22, kuwedzera kwekupisa kwekuwedzera kweiyo thermal yekuwedzera. 4.8×10 ^-4.Iyo dhizaini zvakare yakakura, uye kana dhiri rasvika 1% ~ 2%, resin ichatsemuka, saka iyo inobvumirwa kutakura kushushikana kwegirazi fiber chubhu haipfuure makumi matanhatu muzana yekumanikidzwa kwemuganhu, nepo kabhoni fiber chubhu ine yakakura elastic modulus uye inogona kuchengetedza yakanaka michina zvivakwa pasi peiyo muganho kusagadzikana mamiriro.

Kupfupisa, kabhoni faibha chubhu ine zvakanakira kupfuura girazi faibha chubhu mune mechaniki zvivakwa, asi imwe neimwe ine yayo yekushanda ndima, semuenzaniso, girazi fiber chubhu inodiwa munzvimbo inodiwa insulation.
