This study examines how the stitching density of pitch-based carbon fibers affects the thermal welding efficiency of CF/PEEK composites. Stitching at 5 mm and 10 mm intervals was compared, showing that higher density significantly enhanced through-thickness thermal conductivity-up to 9.740 W/m<middle dot>K. This improvement enabled faster heat transfer and effective welding at lower temperatures. However, lap shear strength remained similar across all samples, with only minor variation. While stitching density had little impact on joint strength, it greatly improved thermal conduction and weld stability. The proposed design offers potential for efficient low-temperature welding of large thermoplastic composite structures.
