Light-Tool Resin Transfer Molding

Project Information

Award Amount:$0.00
Dollars Leveraged:$0.00
Start-End Dates:9/1/05-12/31/06
Description:New plastic resin displacement and reinforcement/flow technology helps to reduce emissions up to 99 percent and the cost of Light-Tool Resin Transfer Molding (L-RTM) as it applies to manufacturing in the fiber reinforced plastic (FRP) industry. The unique combination of several new L-RTM closed mold enhancing technologies can lead to the production of closed mold fiber reinforced products that effectively reduce pollutant HAP/VOC emissions by 85 to 99 percent and produce parts that are lighter, stronger, more accurately and consistently sized as well as competitive in cost to certain open mold alternative products. EPA estimates that over 27 million pounds of styrene and other HAP materials are released per year from resin and gel coat materials by the reinforced plastic composites industry. Preliminary investigations have found that in some cases the surface finish and process issues of L-RTM allow the gel coating spray step to be omitted -- completely eliminating emissions from the gel coat spray process. Because emissions of resin will be driven to nearly zero whenever L-RTM is adopted, worker exposure risks will also be greatly reduced. Thus, demonstration of the process, outreach to the industry, and ultimate implementation and adoption of L-RTM by the industry could add significant emission reduction and augment the Reinforced Plastics Industry NESHAP in gaining additional emission reductions of pollutants to the environment. CMTI has continued to work with the FRP industry as currently organized in the Midwest. Current L-RTM technology implementation could be increased, targeting the open molded systems that could best benefit from the L-RTM process. CMTI has documented the technical performance issues and has tracked the actual in-plant adoption and cost/economics. The documentation and effective communication of the expected success will help L-RTM reach the "critical mass" of adoption that it needs to become a viable and effective method of production. With every L-RTM adoption the potential for reducing emissions is realized. CMTI has conducted workshops and/or performed on-site L-RTM closed mold implementation assessments at individual end-user companies and has worked with open mold companies, as well, to assist them in L-RTM assessment and implementation.
