Examples of Transverse Isotropic materials

Examples of Transverse Isotropic materials

(OP)
Hi,

I am trying to build a table with the most common transverse isotropic materials.
The table will consist of independent engineering constants, Like E1, E2, E3, G12, G13, G23, nu12, nu13.

can someone tip me with names of common tr- iso materials, and maybe abovementioned properties with reference?

Thank you for help in advance.

RE: Examples of Transverse Isotropic materials

A material with transverse isotropy is basically one like a unidirectional composite. These usually come in layers of E-glass, S-glass, HS-carbon and IM-carbon fibers all in any one of about 100 common polymer matrices.

E-glass fibers in a polyester matrix can be as cheap per unit weight (two or three dollars per pound) as carbon steel and IM-carbon/epoxy can cost about 50 times as much. Basalt fibers are in polymer matrix are also becoming common and are a bit more like glass than carbon.

In the plane of the fibers E-glass/polymer is quite flexible (about 1/10th the stiffness of steel) and carbon/polymer is about half as stiff as steel. If you want material as stiff as steel then you can get HM or UHM carbon fibers, but these will be very expensive.

Check out the Hexcel, Cytec, and Toray websites. These all produce both fibers and resin matrixes.

E.g., http://www.hexcel.com/Resources/DataSheets/Prepreg...

PS: if I was making a table I'd use wood, which is more-or-less transversely isotropic.
