carbon/ epoxy orthotropic prepreg properties 1

[eelianx]

Hello,

I would like to find the material properties (values) for MR50/LTM25 carbon/ epoxy orthotropic prepreg necessary for my finite element work.
It would be great if anyone can suggest to me which reference/ internet links/ books where i can find the material properties for carbon-epoxy prepreg

I had been searching in vain for quite some time. so, Any suggestions would be great.

Thanks

Kind regards,
Ee Lian

google.com > enter "MR50/LTM25" > bunch of links with property values

Thanks for the comment.

I did search that way before posting for help on the forum. Many results pop out but it all points back to a few articles which doesn't have the properties that i need.
Thanks

Kind regards,

so what specific properties do you need?

Hi SWComposites

I need the elastic modulus (Ex,Ey,Ez) Poisson's ratios (prxy,prxz,pryz) and shear modulus (gxy,gyz,gxz). Also the failure criteria values

i can find some basic unidirection values in about.com but not all of the properties that i need are available

Any help would be greatly appreciated

Thanks

Kind regards,
Ee Lian

The about.com link has most of what you need (1 = x, 2 = y). For the others use

Ez = Ey
Gxz = Gxy
Gyz = 0.67 Gxy
prxz = 0.3
pryz = Ez/(2Gzy) - 1
