Heat-treatment effects on dimensional stability and mechanical properties of 3D printed continuous carbon fiber-reinforced composites

This paper investigated the heat-treatment effects on the performances of 3D printed continuous carbon fiber (CCF) reinforced composites (CCFRCs). Specimens with different layer distributions were post-treated at different heat-treatment conditions. The heat-treatment influences on material’s crystallinity, porosity and dimensional stabilities with underlying mechanisms were discussed. Flexural properties of the composites were also evaluated by...
