Abstract Scope |
This study investigates the mechanical behavior of Fused Deposition Modeling (FDM) 3D-printed polypropylene (PP) reinforced with carbon fiber (CF), before and after blending with glass fiber (GF) reinforcement. Filaments are fabricated by extruding polypropylene pellets infused with CF and GF at varying ratios, targeting a 1.75 mm diameter for printing compatibility. Test specimens are printed using a MakerBot METHOD X printer and evaluated for tensile strength (ASTM D638), flexural strength (ASTM D790), and interlaminar shear strength (ASTM D2344) using an ADMET Universal Testing Machine. Special emphasis is placed on interlaminar shear strength to assess interlayer adhesion. The study systematically examines the effect of CF-to-GF ratios on mechanical performance to optimize composites for lightweight, high-strength applications such as automotive, aerospace, and electronic enclosures. Results provide critical insights into improving the mechanical properties, structural integrity, and processability of fiber-reinforced PP composites for advanced multi-material additive manufacturing |
