Nowadays, additive manufacturing is being used in various industries
such as automotive, aviation and space, medical applications, etc.
Although additive manufacturing methods offer more freedom in design and
manufacturing, they usually have low production speed and mechanical
properties. Continuous carbon fiber reinforced thermoplastic (CFRTP)
composites are one of the investigated methods in the literature to
increase the mechanical properties of the additively manufactured parts.
This study utilized a production line based upon the melt impregnation
method to obtain continuous carbon fiber reinforced thermoplastic
filaments using polyamide and continuous carbon fibers. In the printing
process, an infrared heat source was utilized to further increase the
mechanical properties by improving the interlaminar bonding. The
mechanical properties of the printed parts were measured using
three-point bending tests. A significant increase was observed in
flexural modulus of elasticity and flexural strength with infrared
heaters at low printing speeds. A maximum value of 418.99 MPa flexural
strength and 52.15 GPa flexural modulus was achieved.
