Hi, I am trying to understand some more on composite materials and i have a question. Let's say i have two materials and i want to produce a composite from those materials. How can i check if a composite is possible from these materials? I have found an equation on the web but i am newbie on these stuff and is difficult to understand them. I also found that to determine how a composite is possible i have to find some data such as the elast. modulus, and spec. gravty. I beleive those numbers can be found for any material so let's say that i have two materials with all the data known. How to check if my composite will work?
