Linear translaminar fracture characterization of additive manufactured continuous carbon fiber reinforced thermoplastic

This work presents the experimental determination of fracture mechanics parameters of composite specimens manufactured by fused filament fabrication (FFF) with continuous carbon fiber reinforced thermoplastic filaments, based on Linear Elastic Fracture Mechanics (LEFM). The critical mode I translaminar fracture toughness (K Ic ) and the critical energy release rate (G Ic ) are found for unidirectional and cross-ply laminates. The specimens were...
