Title : 3D printing of continuous fiber composite by in-site impregnation technique
Abstract : Three-dimension (3D) printing technique for continuous carbon fiber reinforced plastics (CFRP) has been developed based on fused deposition modeling with in-nozzle impregnation technique. A thermoplastics filament and continuous carbon fibers were separately supplied to the 3D printer, and fibers were impregnated with a thermoplastic in the heated nozzle just before printing. The compaction roller was equipped with the nozzle to draw a CFRP filament from the nozzle and consolidate the ejected CFRP. Fiber volume fraction of the printed CFRP was controlled up to 50 %. Mechanical properties of the printed composite were evaluated by several mechanical tests.
