Abstract Fiber‐reinforced composites have found their prominent place in various applications, including aerospace, automobile and marine manufacturing industries, because of outstanding properties obtained during composite preparation. One such aspect improving the property is hybridization, where natural fibers (or both synthetic fibers) are combined to obtain different structures for diverse applications. This research aims hybridize considering Kenaf fabric Kevlar reinforced an unsaturated polyester matrix with proportions.

Abstract This study utilizes the Taguchi optimization technique to investigate effects of FDM processing parameters on Charpy impact strength 3D printed CF/PA composites experimentally and statistically. The four printing employed in experiment are infill density, raster angle, extruder temperature, speed, which were used create experimental plan with L18 orthogonal array. Signal noise (S/N) ratios analysis variance (ANOVA) utilized identify optimum values interactions between process parameters. SEM thermography techniques assess microstructural damage status composite specimens. ANOVA results determined that only three factors–infill temperature–had a statistical significance, while speed did not. outcomes demonstrated optimal density (100%), angle (60°), temperature (260°C), (30 mm/s), maximum contribution 54.19% belonging minimum 2.84% speed. combination these yielded 10.54 kJ/m 2 , resulting an increase almost 150% compared worst‐case situation. approach proves be proficient boost 3D‐printed composites.
