Hey everybody; There is something I don't understand. I need to find the properties(E,Poisson's ratio, G) of e-glass fiber 420 gm bi-bias. I find some interesting websites but each time when they give properties, they don't give the basis weight. So if I understand, mechanical properties are independant of the basis weight and if it's a bi-bias or not. The aim is after applying the rule of mixture. Thanks for your help !
