Automated Fiber Placement of Advanced Materials (Preprint)

摘要

As Composite Materials expand into higher temperature ranges they generally become increasingly more difficult to process with today's proven automated technologies. Automated Fiber Placement has become a standard process for fabricating large complex epoxy skins and shells. Fiber Placement with higher temperature materials, BMIs, and higher service temperature materials, has proven more difficult. Placement of BMIs on the Joint Strike Fighter (JSF) Program and other applications has presented some new challenges for the equipment and process. ATK has been working with the Air Force Research Laboratory to foster improvements in the BMI materials and in the fiber placement processing techniques to achieve rates comparable to Epoxy placement rates. This paper will concentrate on the recent advancements in BMI Materials for Fiber Placement and advancements in fiber placement processing techniques.
