Research Summary

Integration of Composite Part Design and Processing Simulation in Liquid Composite Molding (LCM)

Authors: J. Wang (PhDME), Dr. P. Simacek, and Dr. S. G. Advani

Background: Composite Functional Design & Process Design

LCM Processes and Mold Filling Simulation Tool: LIMS

Motivation: Integration of LCM Simulation with Design Cycle

Approach: Three Levels of Manufacturability Analysis

Example: Manufacturing Analysis for a Trailer

Integration with CAD Software MSC SimXpert

Summary and Conclusions

• Coupling between composite part functional design and process design can reduce prototype development cost and time

• Integrating LCM simulation tools into a CAD environment seamlessly can provide process information to the designer in real time

• Ease in manufacturing and improvement in yield can therefore be achieved


The financial support of this work is provided by the Defense Advanced Research Projects Agency (DARPA) through orthotic project for the Center for Composite Material at the University of Delaware.
Input from Dr. Yarlagadda and Dr. Tierney on the use of the Orthotic geometry and constraints associated with manufacturing allowed us to conduct a realistic simulation.
Thanks to Dan Molligan for the help on the use of CAD software SimXpert
