Synthesis and Mechanical Properties of C/PLA 3D Printing Composites Based on Waste Rice Noodles

Spherical carbon particles were prepared by using waste Guilin rice noodles as raw materials. By blending the rice noodles based carbon (RC) powders with polylactic acid (PLA), A series of black RC/PLA 3D printing composites were synthesized and characterized. The mechanical testing result shows that the RC/PLA 3D printing composites display better mechanical properties than that of pure PLA. Moreover, the composite with carbon treated with high temperature carbonization has better impact strength.
