| description | Mode I interlaminar fracture toughness was investigated for the first time for
continuous carbon fiber reinforced nylon thermoplastics fabricated using fused filament
fabrication (FFF). To illustrate the effect of process temperature on the fracture toughness of the
FFF-fabricated continuous carbon FRP composite, the nozzle temperature, bed temperature, and
printing speed of the laminate were varied. Mode I interlaminar fracture toughness was evaluated
by a standard double cantilever beam (DCB) test. The experimental result shows that Mode I
interlaminar fracture toughness increases with increase nozzle and bed temperatures and decreases
with printing speed. The decrease in the interlaminar properties was discussed on the basis of
fractographic observation derived from optical microscope. |
