| description | The additive manufacturing of high-performance thermoplastics, including high-temperature materials and continuous fiber reinforcement, are extensively being developed worldwide. In this work, we combined laser-assisted in situ consolidation tape laying and fused filament fabrication to manufacture a 100% thermoplastic stiffened panel in three stages with innovative designs using LMPAEK-PEKK carbon fiber-reinforced polymers. The overprinting of gyroid structures on top of ATL laminates assisted by lasers have shown very good adhesion. Mechanical characterization by flatwise and four-point bending tests have shown tensile strength in the range of 10 MPa (flatwise) and 889 MPa (four-point bending). Tomography analysis shows the optimization roadmap to enhance mechanical properties by improving temperature management during manufacturing. |
