Continuous carbon fiber shape memory composites improve mechanical properties of 3D printing

In the recently published 3D Printing of Continuous Carbon Fiber Reinforced Shape Memory Polymer Composites, researchers Yongsan An and Woon-Ryeol Yu explore the mechanical properties challenges that plague many industrial use.

In this study, the researchers experimented with continuous carbon fiber-reinforced shape memory polymer composites (SMPCs)—both thermoplastics and thermosets—in FDM 3D printi.

The researchers tested parameters and printed samples to learn more about the strengths and limitations of smart materials such as SMPs—the ability to change with their environment and then return to their normal sha.

The research team created a custom FDM 3D printer for the study to fabricate continuous fiber-reinforced SMPC par.

They experimented with differences in temperature and printing speed when printing out the samples to be tested, and the team then assessed mechanical and shape memory properti.

"Storage modulus (G''), loss modulus (G") and the viscosity of PLA decrease near its melting point, the researchers wrote in the pap.

"The CF-free PLA filaments were smoothly extruded from the nozzle, regardless of whether their diameter was larger than the fusion ar.

There are many challenges here, such as CF not fully coating P.

According to the researchers, the printed SMPC showed better mechanical properties in the fiber direction compared to conventional 3D printed polyme.

The strength and stability of mechanical properties is an ongoing challenge in 3D printing, but as researchers resolve to perfect materials and processes for testing from carbon lattices to titanium, as well as for incremental manufacturing techniques that examine biocompatibility issues, There is room for continuous improveme.
