High-speed reactive
RTM process simulation for
the automotive industry
ESI Group is conducting research
with Ecole Centrale de Nantes
(ECN) to propose an innovative
industrial computation technique
for dual-scale flow simulations.

omposite parts are produced by
combining fabrics made of carbon
or glass fibres with polymeric resins.
Resin Transfer Moulding (RTM) is one
of the processes available to manufacture
composite parts.
26 jec composites magazine / No105 June 2016
In the RTM process, a preform made of
fibrous material is placed in the closed
cavity of a mould and a thermosetting
or thermoplastic resin is injected in the
cavity to fill the spaces between the
fibres. After curing or solidification, the
resin gives the final shape to the part. In
recent years, interest has been growing in
the use of this process to produce structural parts, especially in the automotive
industry. To reach short cycle times
and increase productivity, fast-curing
low-viscosity resins have been developed. The components of these resins
are mixed on line (at the mould inlet)
prior to injection in the mould cavity.
However, the fast curing process has a
significant influence on the evolution of
temperature (the curing reaction is exothermic) and on the viscosity (viscosity
decreases with increasing temperature
but increases with the crosslinking of
monomers) during injection. Due to
these thermo-chemo-rheological couplings, predicting the optimum injection
strategy and process parameters is very
difficult and requires heavy, expensive
experimental trial-and-error campaigns.
