The layer-wise architecture limits their use in complex 3D geometries and leads to uneven structural performance in multi-axial load scenarios. This study introduces a novel planar fibre-winding process for manufacturing topologically optimized composite structures. The proposed method utilizes a continuous process where a carbon fibre roving is wound onto a complex 3D printed winding core. This approach enables the creation of a truss-like structure that closely follows the optimal load paths. The winding process is automated using a 3-axis gantry system, allowing precise fibre placement to form spatially complex structures. The mechanical performance of a complex wound structures was evaluated against traditionally milled aluminium parts. Tensile testing of dry rovings and composite samples provide insights into the effects of process-induced damage on the mechanical performance of the composites. Significant performance improvements compared to conventional metal component design is achieved. The composite structures showed a 55 % reduction in weight compared to milled aluminium components, while achieving a 160 % increase in specific stiffness in out-of-plane bending tests. The process also demonstrates high reproducibility and minimized material waste.

Carbon as filler materials were obtained by pyrolyzing the SCG waste. As the biomass derived carbon generally has inert surface properties, it causes poor compatibility between the filler and polymer matrix yielding inferior thermal and mechanical properties of the composites. So, the properties of pyrolyzed carbon in the present work were tailored by SF<sub>6</sub> plasma treatment at different time durations. The surface functionalization of carbon materials and optimized plasma treatment time were analyzed from different characterizations. Fourier Transform Infrared Spectroscopy (FTIR) and X-ray Photoelectron Spectroscopy (XPS) reveals 15 min plasma treatment carbon is the optimized one with highest fluorination and semi-ionic C-F bonding. Due to the highest fluorination, the I<sub>D</sub>/I<sub>G</sub> ratio i.e. the defect density is found to be maximum for 15 min plasma treated carbon from the Raman spectra. The 15 min plasma treated carbon with highest fluorine functionalization as a filler exhibits 33.8 % and 13.97 % improvement in tensile modulus and tensile strength in comparison to neat HDPE matrix.
