  1. Have we Improved Processability for Liquid Molding with Process Modeling ? Injection & Compression Molding Liquid Composite Molding

  2. Domain of Composite Molding Processes

  3. Macro flow modeling issues in Liquid Composite Molding 14775

  4. Micro flow modeling issues in Liquid Composite Molding Vent Vent Injection Injection Unsaturated Effects Preform Deformation & Compaction Micro Void Formation 14785

  5. Issues and Challenges in Liquid Composite Molding Issues • Preforming • Complete Saturation and Voids • Injection and Vent Locations • Process Control • Reliability and Repeatability Challenges • Three Dimensional Flow Modeling • Saturation Physics • Dimensional Tolerances • Flow Control • Distribution Media Design • Location of Resin Injectors • Automation • Large and Complex parts

  6. Will modeling improve preform Manufacturing and Processability ? A B knots with b.c.’s s1 s2 C zoom projection of y axis projection of y axis

  7. Can one improve yield despite uncertainties in process? Can modeling help? Preform Nesting Flow Channels Resin Arrival on Tool Surface

  8. Future Can one introduce Control and Automation to address uncertainties in process and materials ? Past

  9. The Road from Injection Molding to Liquid Composite Molding Has Process Modeling been useful in Injection Molding? Yes! NSF Center for Injection Molding made CAE an integral Part of Manufacturing Why is the tech transfer so slow in Liquid Composite Molding (LCM)? Is the Process more forgiving ? Has it moved into the commercial zone from Military Arena ? What more can be done to move it into the commercial zone ? Are process models already advanced to the stage of deployment? Why LCM industry is not willing to embrace the role of modeling?
