Evaluation of Tensile Behavior of 3D-Printed Fiberglass-Reinforced Nylon Composites

In this study, the elastic modulus of the 3D-printed Nylon filament reinforced with chopped carbon fiber as the matrix material and fiberglass (FG) as the reinforcement material, was evaluated using the Rule of Mixtures. Different configurations with various numbers of FG layers were added to the specimen, and all were subjected to tensile tests. The elastic modulus from the calculated values using ROM ( Ε c ) and experimental results from the actual tensile test ( E ) of the 3D-printed composite material were compared. The results showed that the discrepancy between the Ε and Ε c increases as the number of reinforcement layers also increases.
