Goodday, I am currently a fourth year Mechanical Engineering Student. My fourth year project is to mix two resins (Rigid and tough 1500) with different ratio’s and test the mechanical properties. I am busy with my literature review however, I am finding difficulty studies on this subject. I would like to know if there is someone that has tried mixing different resins and what were thier properties ---
