Implication

This analysis evaluates the in-plane mechanical behavior of 3D-printed thermoplastic composite laminates, revealing implications for engineering applications.

Key Points

The tensile strength of 3D-printed fiber-reinforced composites improved significantly by 2.3x compared to unreinforced materials.
Digital image correlation (DIC) methods were used to obtain strain fields during tensile testing across various laminate configurations.
The research compared experimental results to Classical Laminate Theory, indicating its limitations in predicting stiffness beyond early deformation stages.
Void and defect challenges in additive manufacturing were explored, affecting the actual fiber content from about 60 to 20 in printed parts.
