Detecting Multi-Scale Defects in Material Extrusion Additive Manufacturing of Fiber-Reinforced Thermoplastic Composites: A Review of Challenges and Advanced Non-Destructive Testing Techniques

Polymers, Journal Year: 2024, Volume and Issue: 16(21), P. 2986 - 2986

Published: Oct. 24, 2024

Additive manufacturing (AM) defects present significant challenges in fiber-reinforced thermoplastic composites (FRTPCs), directly impacting both their structural and non-structural performance. In structures produced through material extrusion-based AM, specifically fused filament fabrication (FFF), the layer-by-layer deposition can introduce such as porosity (up to 10-15% some cases), delamination, voids, fiber misalignment, incomplete fusion between layers. These compromise mechanical properties, leading reduction of up 30% tensile strength and, cases, 20% fatigue life, severely diminishing composite's overall performance integrity. Conventional non-destructive testing (NDT) techniques often struggle detect multi-scale efficiently, especially when resolution, penetration depth, or heterogeneity pose challenges. This review critically examines FRTPCs, classifying FFF-induced based on morphology, location, size. Advanced NDT techniques, micro-computed tomography (micro-CT), which is capable detecting voids smaller than 10 µm, health monitoring (SHM) systems integrated with self-sensing fibers, are discussed. The role machine-learning (ML) algorithms enhancing sensitivity reliability methods also highlighted, showing that ML integration improve defect detection by 25-30% compared traditional techniques. Finally, potential self-reporting equipped continuous fibers for real-time situ SHM, investigated. By integrating ML-enhanced accuracy efficiency be significantly improved, fostering broader adoption AM aerospace applications enabling production more reliable, defect-minimized FRTPC components.
