Composite material properties needed.

Composite material properties needed.

Composite material properties needed.

(OP)
I am working with a FEA program, trying to adapt it to the needs of the company where I work. It produces compensators and expansion joints. At the moment I am working with the expansion joints, and I can simulate their shape, I can mesh them and I can apply constraints and loads on them. The problem appears with the joints' materials. As they are not very common, they are not in the program's library. Here is where I would need your help. The most important materials we use are:
    - Rubber impregnated tire-cord (Rayon)
    - Silicone coated glass fabric
    - PTFE film laminated over fluoroplastic coated glass fabric
    - Kevlar fabric
The data I need to define these materials is:
    - Young's modulus
    - Poisson's ratio
    - Mass density
    - Yield stress
I have been looking for these values in the web for a long time, with no result. I would be grateful if you could send me any of the information on these materials.

RE: Composite material properties needed.

Virtually none of those materials are isotropic, and most may have nonlinear material properties.  I would be very surprised if your FEA package would even model a fiber-reinforced elastomer material. -ldp
