Experimental Study on Laser Plasticizing Polyamide 12
Advanced Materials Research, 2012Considering the efficiency and microscale requirement of melting polymer in micro-injection process, we present an experimental analysis of the CO2 laser irradiating Polyamide 12 (PA12) based on the photo-thermal effect of laser-materials interaction. The orthogonal experiments of laser plasticizing were designed by Taguchi method of Minitab software ...

Orientation of the lamellar crystals in polyamide 12
Polymer, 1993Three types of oriented samples of polyamide 12 have been investigated by electron microscopy, and small- and wide-angle X-ray diffraction: (a) sedimented mats of single crystals obtained by filtration from dilute solution; (b) melt crystallized samples oriented by unidirectional rolling and; (c) samples obtained by extrusion just below their melting ...

Coating of polyamide 12 by sol–gel methodology
Journal of Thermal Analysis and Calorimetry, 2013The combination of sol–gel methodology with rapid prototyping (RP) produces functionalized 3D structures with potential applications in various fields. However, this combination has been little explored. In this paper, we used the sol–gel method to deposit vanadium isopropoxide onto polyamide (PA12) constructed by RP and pretreated with acetic acid, to

Rheological changes of polyamide 12 under oscillatory shear
AIP Conference Proceedings, 2014Changes in material properties as well as process deviation prevent Laser Sintering (LS) technology from manufacturing of quality assured parts in a series production. In this context, the viscosity of Polyamide 12 (PA12) is assumed to possess the most significant influence, as it determines the sintering velocity, the resistance towards melt formation

Nanocomposites based on a synthetic layer silicate and polyamide-12
Acta Polymerica, 1998The swelling behavior of a synthetic three-layer silicate caused by 12-aminolauric acid is studied by wide angle X-ray scattering. The swelling process as a function of the 12-aminolauric acid concentration can be separated into two regimes; i) cation exchange of inorganic cations by protonated 12-aminolauric acid and ii) further diffusion of excess ...

Novel polyamide 12 based nanocomposites for industrial applications
Journal of Polymer Research, 2017In this paper novel electro-active polyamide 12 (PA12) based nanocomposites were prepared though melt compounding by adding different kinds of carbonaceous nanofillers. The thermo-electrical properties of the bulk samples were then compared with those of the corresponding fibers.

The influence of the orientation and of the temperature on the mechanical properties of the polyamide 12 (PA12) and the polyamide 12 reinforced with glass beads processed via Selective Laser Sintering was analyzed. Tensile and fracture tests were performed at −50 °C, 23 °C and 50 °C with applied load perpendicular and parallel to the layered structure.
