Rubber state of cure theory

Rubber state of cure theory

Rubber state of cure theory

I am trying to understand how a rubber sample state of cure changes with time. Up to now I have created a temperature plot in which the temperature is known at each point within the rubber component however, I am having difficulty understanding how it cures.

The information I have currently is a torque vs time graph (obtained from a isothermal MDR test) and I the geometry the test was conducted on. After searching online I found the following equations:

Will the data I have and the equations in the above link be enough for me to determine how the state of cure changes with time from the temperature plot which I currently have?

Note, I want to keep this somewhat simple therefore, I am not going to be including the heat generated from the curing reaction and make the assumption that the rubber surface temparature is the same as the mould temperature.

RE: Rubber state of cure theory

I have looked over this a few times now and have realized that this theoretical analysis requires either a Calorimeter test result to determine change in enthalpy or results obtained from MDR in Scanning Mode. I have neither of these therefore, could anyone please suggest a method for cure analysis which requires the data that I do have?

Thank you.
