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?

Anyone? Too many members and no one knows what information is needed and how to calculate if a composite is possible? I have the specific gravity and elastic modulus of those materials. Do i need more information?
Thank you

Try making it.

One thing to consider beforehand is if the sizing (coating) of your fiber is compatible with your matrix. If the chemistry doesn't work you're going to have an issue with resin penetration and bonding.

You can look at mechanical properties and use laminate theory to try and determine what your end-properties will be. Other practical considerations are how quickly the matrix cures, what conditions are needed to initiate the reaction and also promote full cross-linking.

Good luck.
