heal.abstract
The present dissertation thesis is one of the first worldwide efforts to study the behavior of 3d printed fiber reinforced honeycomb structures. The 3d printer that has been used for the experiments is ‘’Markforged Mark Two’’. Markforged printers are unique in their ability to lay continuous strands of fibers (carbon, glass and kevlar) inside 3D printed parts to achieve strengths comparable to metals. The novelty in this research is the fact that the fiber reinforcement will be inserted in the total body of the honeycomb structure, despite the existent papers that try to add reinforcement s in specific parts of specimens. Another important effort that has been made in this dissertation thesis, is to simulate 3d printed materials in Finite Element Analysis software. The ANSYS Workbench has been selected for this purpose. 3d printed technology is really new and CAE software programs a re not really appropriate to study these materials yet. However, ANSYS tries to overcome these problems with the announcement of 3DSIM which is a software that will be able to simulate 3d printed structures. ANSYS hopes that by combining its flagship softw are with exaSIM ( additive manufacturing simulation workflow), and FLEX ( helps to develop 3D printing operations and best practices based on one’s materials and equipment selections) , it will be able to help users reduce the risks, trial and error of implementing a 3D printing workflow. It also hopes to speed up the installation and optimization of 3D printing equipment  1    2    In addition the proper and more accurate simulation of 3d printed structures will be possible. Finally, another new approach that h as been studied in this thesis, is to make high resistant honeycomb structures that will be able to be sandwiched between other more flexible materials. This new approach may have great impact in several aerospace applications, where lightweight and less s tiff honeycomb structures are being sandwiched by carbon fiber panels in order to acquire the proper mechanical properties until now. The new proposal, that will be presented in this research, will make possible the elimination of the use of fibers (carbon , glass or Kevlar) , by adding them in special selected parts of the honeycomb structure and remove them from the bottom and top panels.
