In this study, multi-axial warp knitted thermoplastic composites were fabricated by our-developed Micro-braiding technique. Cross-sectional observation, tensile test and 3 point bending test were performed. The composite with good impregnation state was obtained under appropriate molding conditions, consequently high mechanical properties were achieved. The multi-axial warp knitted fabric composite without unimpregnated region had the equivalent mechanical properties with unidirectional composite laminates. Moreover, continuative fabrication method was developed, in which compression machine equipped with swing device in order to enhance the impregnation and to expel air. From these results, continuous fiber reinforced thermoplastic panel was realized by combining braiding and knitting technique. |
