Sib piv carbon fiber tube nrog txhuas raj

Kev ntsuas ntawm carbon fiber thiab aluminium

Nov yog cov ntsiab lus siv los sib piv cov khoom sib txawv ntawm ob cov ntaub ntawv:

Modulus ntawm elasticity = "qhib" ntawm cov khoom.Qhov piv ntawm kev ntxhov siab rau strain hauv cov khoom.Txoj kab nqes ntawm txoj kev ntxhov siab-txoj kab nkhaus ntawm cov khoom siv hauv nws thaj tsam elastic.
Qhov kawg Tensile Strength = Qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus ua ntej tawg.
Qhov ntom = hnyav rau ib chav tsev ntim ntawm cov khoom.
Tshwj xeeb nruj = elastic modulus muab faib los ntawm cov khoom ntom ntom.Siv los sib piv cov ntaub ntawv nrog ntau qhov sib txawv.
Tshwj xeeb Tensile Strength = Tensile Strength muab faib los ntawm cov khoom ntom ntom.
Nrog rau cov ntaub ntawv no hauv siab, cov lus hauv qab no piv cov carbon fiber thiab txhuas.

Lus Cim: Ntau yam tuaj yeem cuam tshuam rau cov lej no.Cov no yog generalizations;tsis yog kev ntsuas kiag li.Piv txwv li, cov ntaub ntawv sib txawv ntawm cov khoom siv carbon fiber ntau muaj nrog ntau zog los yog lub zog, feem ntau ntawm kev lag luam tawm ntawm kev txo qis hauv lwm yam khoom.

Kev ntsuas Carbon Fiber Aluminium Carbon / Aluminium Sib piv
Elastic Modulus (E) GPa 70 68.9 100%
Tensile zog (σ) MPa 1035 450 230%
Qhov ceev (ρ) g/cm3 1.6 2.7 59%
Kev nruj nruj (E/ρ) 43.8 25.6 171%
Lub zog tensile tshwj xeeb (σ/ρ) 647 166 389%

 

Lub sab sauv qhia tau hais tias qhov tshwj xeeb tensile lub zog ntawm carbon fiber yog hais txog 3.8 npaug ntawm txhuas, thiab qhov tshwj xeeb nruj yog 1.71 npaug ntawm txhuas.

Kev sib piv ntawm thermal zog ntawm carbon fiber thiab txhuas
Ob lwm yam khoom uas qhia qhov txawv ntawm carbon fiber thiab txhuas yog thermal expansion thiab thermal conductivity.

Thermal expansion piav qhia qhov kev hloov pauv ntawm qhov ntev ntawm cov khoom raws li qhov kub thiab txias hloov.

Ntsuas Carbon Fiber Txhuas Txhuas Txhuas / Carbon Sib piv
Thermal Expansion 2 in/in/°F 13 in/in/°F 6.5

Ntsuas Carbon Fiber Txhuas Txhuas Txhuas / Carbon Sib piv
Thermal Expansion 2 in/in/°F 13 in/in/°F 6.5
