  • Publication number: 20120073726
    Abstract: 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.
