| Abstract Scope |
As an important structure in lightweight components design, the 3D lattice structures have the advantage of being strong and effectively absorbing impact force. However, directly fabricating lattice structures using continuous carbon fiber reinforced polymer (C-CFRP) composites with thermosetting materials is still challenging. In this study, two methods are used to prepare lattice structures: manual assembly and 3D printing methods. In the manual assembly method, the shape of the pyramidal toolpath is fixed through the mold and post-processed at high temperatures to form individual toolpaths. The individual toolpaths are then fixed using a laser and assembled manually into a six-layer pyramidal lattice structure. In the 3D printing method, a strategy to directly prepare the lattice structure of continuous carbon fibers using 3D printers is proposed by studying the properties of thermosetting materials. The free-hanging lattice structure is formed without any auxiliary tools or post-curing processes. Under laser curing, single toolpaths and 3D triangle lattice toolpaths are formed. Further detailed studies of the processing parameters of a single toolpath and modified toolpath enables the preparation of overlapping toolpaths and complex free-hanging lattice structures. These results provide a valuable reference for directly utilizing 3D printing to fabricate thermosetting carbon fiber lattice structures. |
