Figure 14. Polar diagram of grahite/epoxy Poisson's modulus n 32 for various fiber volume fractions, in GPa.
NOTE: yellow, green, and purple line indicates negative Poisson's ratio.
If the link above is selected a JWave form appears, as shown below.
With the mouse highlight and change the numbers in the form on the right and select the "Update Plot" button at the bottum of the form.
