I want to know material property of CFRP

Altair Forum User

HI,

 

I would like to know the properties of the composite material consisting of epoxy(40%) and carbon fiber(60%) with these properties.

 

	specimen
	Epoxy (Resoltech 1800)	CF (Toray T700)
r (g/cm3)	1.10-1.12	1.8
E1 (MPa)	2703-3708	230000
E2 (MPa)	E1	29273*
E3 (MPa)	E1	E2
G (MPa)	2746.7*	25091*
n12	0.35*	0.25*
n31	n12	0.0318*
n23	n12	0.2*

 

 

 

 

Stacking the carbon fiber angle of 0 ° 45 ° 90 ° -45 -45 90 ° 45 ° 0 ° to make a CFRP..

 

And to obtain the properties for MAT25 type (in Radioss) of CFRP.

 

Material properties for MAT25 are Rho_Initial, E11, E22, E33, Nu_12, Iflag, G12, G23, G31, EPS_t1, EPS_m1, EPS_t2, EPS_m2, Wp_max, Ioff, Ratio, SIG1_yt, b1_t, n1_t, SIG1max_t, SIG2_yt, b2_t, n2_t, SIG2max_t, SIG1_yc, b1_c, n1_c, SIG1max_c, EPS1_c1, EPS2_c1, SIG2_yc, b2_c, n2_c, SIG2max_c, EPS1_c2, EPS2_c2, SIG12_yt, b12_t, n12_t, SIG12max_t.

 

Please show me how to know this properties.

Hi @domado

 

I am not sure what exactly you would like to know. If you are looking for material properties, please contact the supplier for the same.
