Educational Presentations at COMPOSITES 2013 – Orlando, FL USA

22 January 2013

CCG will be presenting three educational sessions at ACMA’s COMPOSITES 2013 conference in Orlando, Florida, taking place January 29-31, 2013.

On Tuesday, January 29 at 11:00am Eastern, Belle Blanding will be presenting a session titled “A Detailed Look at Pressure Behavior During Vacuum Infusion.” Composites made by vacuum infusion processing can have different levels of quality. The level of vacuum pressure used before, during and after the infusion influence the quality of the final composite. This presentation will look at how the pressure works inside the infusion as resin is filling the cavity. We’ll discuss what influences the vacuum pressure during the infusion and how different pressures affect the final composite. Composites Consulting Group has done research investigating these issues. We’ll present conclusions from this research on vacuum pressure behavior and offer helpful suggestions for optimizing the infusion process based on the research.

On Wednesday, January 30 at 3:00pm Eastern, Dean Callander will be presenting a session titled “Double Bagging Process in Marine Composites.” Marine manufactures are embracing the vacuum infusion process (VIP). Reasons include part superiority, environmental, health and employee retention concerns. VIP is also being considered by manufacturers using prepreg materials as a viable cost effective option. We’re now beginning to see more inquiries about the double bag infusion process, and it’s become one of the latest “buzz” words in the marine manufacturing arena. This session reveals testing done to assess the process and presents a case study on how the double bagging process is being employed by one marine manufacturer.

Also on Wednesday, January 30 at 3:00pm, James Jones will be presenting a session titled “Engineering Laminates for Infusion.” When making the switch from open molding to vacuum infusion, it is obvious that processing characteristics of laminate materials must be taken into account. However, many people don’t consider the effects on mechanical properties. In some cases, a structure must be re-engineered entirely. This session will cover the differences in laminate properties achieved with infusion compared to open molding. It will also explore the processing characteristics and mechanical properties of common composite materials and infusion-specific products. In addition, tips will be given on converting open mold laminates to infusion friendly laminates in order to take advantage of the benefits of infusion without compromising strength, stiffness, weight or labor.
