ESI
Group (ISIN FR0004110310), pioneer and world-leading supplier of
digital simulation software for prototyping and manufacturing processes,
announced today the release of several innovations in the field
of numerical simulation of Liquid Composite Molding (LCM) and
manufacturing process analysis, thanks to its partnership with École
Polytechnique de Montréal. A long-term agreement was signed with École
Polytechnique de Montréal in 2007 aimed at developing, validating and
industrializing PAM-RTM,
ESI’s
simulation-based design composite solution for Resin Transfer Molding
(RTM) and resin infusion processes.
The following innovations, developed by the Chair on Composites of High
Performance (CCHP, http://cchp.meca.polymtl.ca)
at École Polytechnique de Montréal, are progressively being integrated
into the existing PAM-RTM
software:
-
Optimization of the void distribution in an RTM composite part through
injection flow rate (VoidOpt module);
-
Rapid RTM flow simulation (OneShot module);
-
Conditional opening of injection ports and vents during resin
injection (Trigger Manager module);
-
Incorporation of simultaneous filling and curing simulations including
the overfilling phase and the evacuation of excess resin at the end of
the filling cycle;
-
Automatic definition and optimization for the location of multiple
injection ports in a RTM mold based on genetic algorithms (GenPorts
module);
-
Articulated injection-compression (Articulated Compression RTM or
ACRTM process).
While PAM-RTM
version 2008 already includes the void optimization module, the upcoming
version 2009 will feature the quick One-Shot simulation module
that can be used upfront to accelerate the process development and
find the optimal positions of injection ports.
