TITLE
On the Incubation Time Computation in Resin Transfer Moulding Process Simulation

ABSTRACT
Liquid Composites Moulding (LCM) processes simulation requires an accurate treatment of the advection equation governing the evolution of different properties related directly or indirectly to the fluid injected into the mould. The incubation time constitutes an example of those properties. It is defined as the time elapsed since the reactive mixing, and its accurate prediction is of major importance for simulating the curing reaction. In the case of complex moulds (with multiple injection points, racetracking effects, different permeability areas...) the incubation time on the melt front could be different to the injection time. Due to the fact that the incubation time is not defined in the empty part of the mould, its updating needs a particular treatment. This paper proposes new numerical strategies for the calculation of the incubation time in mould filling simulation of moulds containing reinforcements.
