Automated Fiber Placement (AFP) technology enables the efficient production of large carbon fiber reinforced composite structures with complex surfaces. The TORRESLAYUP delivers the highest productivity and reliability to lay down aerospace carbon fiber components. carbon fiber) pre-impregnated (prepregged) with thermoset or thermoplastic resin. The objective of this lab is to familiarize the students with the composite materials layup process. see full image. PlyGage is a 3D digital composite repair solution. These consistency improvements eliminate the defects that occur with traditional carbon fiber during the initial hand-layup process (due to human error).
