Abstract Scope |
A new manufacturing method was developed to fabricate 3D woven fabric preforms. The new method can solve problems such as delamination and fiber buckling in composites. The new 3D weaving equipment allows for continuous and rapid production of 3D woven fabric preforms with various 3D structures. We manufactured lightweight 3D woven carbon fiber-reinforced composites using the 3D fabric preforms and epoxy resin via the resin transfer molding process. The internal architecture of the 3D composites was evaluated using micro-computed tomography and compared to the 3D modeling results; it was confirmed that 3D fabric preforms with the desired structure can be manufactured successfully by adjusting the weaving conditions of our novel weaving machine. Lastly, A neural network is constructed to relate the elastic constants with the manufacturing parameters and will be used to explore specific 3D woven structure, e.g., the mechanical properties of which exhibit isotropic behavior in 3D. |
