| Abstract Scope |
Additive Manufacturing is conventionally used to create structures through extruding plastic or metal layer by layer. In the case of polymer processes, fibers are typically added to increase stiffness and reduce warping during building. The of the fiber exiting the nozzle can impact the overall mechanical properties of the structure. Using Long Fiber Pellets can increase the starting length of the pellets to help increase the average fiber length coming out from the extruder. However, extruded long fiber materials tend to have low fiber alignment and high porosity leading to poor mechanical properties. By using a blend of materials and a static mixing nozzle, consolidated beads can be created to produce more stable and solid structures while added a fixed amount of long fiber into the extruded bead to increase mechanical performance. |
