Ceev: Qhov ceev ntawm carbon fiber ntau li ntawm 1.5 mus rau 2.0 g / cm³, uas nyob ntawm feem ntau ntawm cov carbonization kub, ntxiv rau cov qauv ntawm cov precursor fiber. Feem ntau, tom qab siab -kub (3000 degree) graphitization kho, nws qhov ceev tuaj yeem ncav cuag 2.0 g / cm³.
Coefficient ntawm Thermal Expansion: Lub coefficient ntawm thermal expansion ntawm carbon fiber txawv ntawm lwm cov fibers, exhibiting anisotropy. Nws yog qhov tsis zoo rau cov kev taw qhia fiber ntau (-0.90 x 10⁻⁶ rau -0.72 x 10⁻⁶ K⁻¹), thiab zoo perpendicular rau cov kev taw qhia fiber ntau (22 x 10⁻⁶ txog 32 x 10⁻⁶ K⁻¹).
Tshwj xeeb Thaum tshav kub kub muaj peev xwm: Lub peev xwm kub ntawm carbon fiber feem ntau yog 7.12 x 10⁻¹ kJ/(kg·K). Thermal conductivity txo nrog nce kub.
Specific Resistivity: Qhov tshwj xeeb resistivity ntawm carbon fiber nyob ntawm seb hom fiber ntau. Ntawm 25 degree, siab -modulus carbon fiber muaj ib tug resistivity ntawm 775 mΩ / cm, thaum siab - lub zog carbon fiber muaj ib tug resistivity ntawm 1500 mΩ / cm. Cov pa roj carbon fiber muaj qhov zoo electromotive quab yuam (EMF), thaum aluminium alloy muaj qhov tsis zoo EMF. Yog li ntawd, tshuaj corrosion tuaj yeem tshwm sim thaum carbon fiber ntau yog siv ua ke nrog aluminium alloys.
