I have question for carbon UD's stiffness.

Hi, I'm trying to use some UD carbon.
So, I have searched TDS of T700 and M46J.
I heard T700 have low stiffness and high strength, M46J have high stiffness and low strength.
But, There are no properties for stiffness of carbon.
Can you help me??

By stiffness it sounds like you're talking about tensile modulus; basically this is the amount that the fibre will stretch by under a given tensile load.
You should be able to find tensile modulus properties for both of the fibres you mentioned.

I hope this helps.

thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
