A simulation of the non-isothermal resin transfer molding manufacturing pro
cess accounting for both the filling and the consolidation stage has been d
eveloped. The flow of an exothermally reactive resin through a porous mediu
m has been analyzed with reference to the Darcy law, allowing for the chemo
rheological properties of the reacting resin. Thermal profile calculations
have been extended to a three phase domain, namely the mold, the dry prefor
m and the filled preform. The mold has been included in order to evaluate t
he thermal inertial effects. The energy balance equation includes the react
ion term together with the conductive and convective terms, and particular
attention has been devoted to setting the thermal boundary condition at the
now front surface. The moving boundary condition has been derived by a jum
p equation. The simulation performance has been tested by comparing the pre
dicted temperature profiles with experimental data from literature. Further
numerical analysis assessed the relevance of using the jump equation at th
e flow front position for both filling time and thermal profile determinati
on.
