Heat produced during curing process.

Heat produced during curing process.

Heat produced during curing process.


I need to calculate how much of heat is released from a composite material during RTM6 the curing process in autoclave. I have specific heat, density and thermal conductivity of the material.
Can anyone help me how to calculate how much heat is released from that material during the process as i need to give it as input to my fluent file


RE: Heat produced during curing process.

None of those properties will help, you have to look for the reaction (or curing) enthalpy, also referred to as the exotherm. A typical value for epoxy would be approximately 300 J/g, but it will depend on the specific material. The material supplier will be able to provide this value.

I have a curing reaction for RTM6 material, but how to find out the heat release rate?

Thank you

RE: Heat produced during curing process.

A Differential Scanning Calorimetry test of the material can provide the released enthalpy at specific temperature ramp rates.
