Patent application number | Description | Published |
20110083605 | RESIN APPLICATION AND INFUSION SYSTEM - An application and infusion system for applying a resin to one or more fiber tows and for infusing the fiber tows with the resin, wherein each of the fiber tows is moving at a respective fiber speed. The application and infusion system includes a deposition and infusion system comprising one or more nozzles configured to deposit the resin on a respective one of the fiber tows. The system further includes a controller configured to control a flow rate of the resin through each of the nozzles relative to the fiber speed of the respective ones of the fiber tows. Other aspects of the application and infusion system are also provided. | 04-14-2011 |
20110155849 | RESIN INFUSION APPARATUS AND SYSTEM, LAYUP SYSTEM, AND METHODS OF USING THESE - A resin infusion apparatus and system, layup system comprising the same, and methods of using these are provided. The resin infusion apparatus comprises a hollow cylinder having a plurality of pores perforating an arcuate surface thereof. The interior of the cylinder is provided with one or more flow restrictors that assist in controlling the flow out of the pores of the cylinder. Laminates made of prepregs prepared using the apparatus and/or system may thus be essentially free of voids. | 06-30-2011 |
20120073726 | Resin Delivery, Application and Infusion System and Integrated Layup System and Method of Use - An automated in-line feed-through system integrating the delivery, application and infusion of a resin to one or more fiber tows and layup of the one or more infused fiber tows to form a composite structure. The system includes an automated resin delivery, deposition and infusion system configured to deposit the resin on a respective one of the one or more fiber tows and form the infused fiber tows. The system integrates an automated layup system including a compaction roller configured to adhere the one or more infused fiber tows to a substrate. The system further includes a controller configured to control a flow rate of the resin, control the temperature of the resin, the infused fiber tows and the automated layup system, and control tension of the one or more infused fiber tows within the automated layup system. Other aspects of the automated in-line system are also provided. | 03-29-2012 |
20120073730 | System and Method for the Automated Delivery and Layup of Resin Infused Fibers - An automated in-line feed-through system integrating the delivery, application and infusion of a resin to one or more fiber tows and layup of the one or more infused fiber tows to form a composite structure. The system includes an automated resin delivery, deposition and infusion system configured to deposit the resin on one or more fiber tows and form the infused fiber tows. The system integrates an automated layup system including a compaction roller, a guide roller coupled to an extending cylinder, and an auxiliary roller configured to adhere the one or more infused fiber tows to a substrate. The system further includes a controller configured to control system parameters, including the control of tension of the one or more infused fiber tows within the automated layup system. Other aspects of the automated in-line manufacturing system are also provided. | 03-29-2012 |
