New 10% Rule

Dear All,

Here is a note from Professor Tsai on the 10% rule:

If we are limited to balanced laminates, the requirement is to have a minimum 10% each of [+45] and [-45]. The bounds would be 20 percent of [±45]. This is shown in the revised plot "10_perecent_rule" found in today's folder. The reduction in possible laminates within this restricted family will be 28, less than one half of the original 66.

This was pointed out by Faisal Javed. We wish to thank him for the contribution.
