Tensile performance of continuous fiber reinforced thermoplastic printed by fused filament fabrication

In this paper, the tensile performance of 3D printed continuous fiber reinforced thermoplastic materials is investigated. Continuous carbon fiber and Polyethylene terephthalate glycol (PetG) are employed as reinforcement and matrix, respectively. Pure solid plastic infill, unidirectional fiber infill, and +45/-45 fiber infill patterns specimens are selected for printing and testing.
