Microstructural and mechanical characterization of PA12/MWCNTs nanocomposite manufactured by selective laser sintering

A new method to prepare composite powders customized for high temperature laser sintering

“…For a long time, polyamides (PA11 and PA12) have predominantly been used for a standard LS process, due to their excellent processability. The incorporation of reinforcement to polyamides can lead to composite components with improved performance and widened applications [2][3][4]. However, for harsh environments such as aerospace, defence and gas applications, the currently available polymers for LS cannot meet these requirements.…”

Reactive microencapsulation of carbon allotropes in polyamide shell-core structures and their transformation in hybrid composites with tailored electrical properties

“…Among them, aliphatic polyamides are quite frequently employed since they possess a unique balance between price, processability, chemical properties and mechanical resistance. Thus, polyamide 6 (PA6), polyamide 12 (PA12) and polyamide 6.6 (PA66) have been melt-mixed with different grades of CNT for studying the structure, morphology, mechanical and electrical properties of the resulting hybrid composites [3,[12][13][14][15][16][17][18][19][20]. It seems that the extremely high stiffness, electrical and thermal conductivity combined with their high aspect ratio makes CNT suitable fillers for conductive polyamide nanocomposites with prospective applications in electronics, packaging and automotive industries.…”

Processing and characterizations of 2%PF/silica sand core–shell composite powders by selective laser sintering with a higher transmittance fiber laser

“…In the recent years, SLS has been further extended to fabricate the nanocomposite component to pursue much higher properties. Salmoria et al [18] investigated the microstructural and mechanical characterizations of PA12/MWCNTs nanocomposite manufactured by SLS. The composite powders were mixed by mechanical method before laser sintering.…”
