A Mechanical Model for Stress Developmentin PA12 Tube Extrusion

International Polymer Processing, 2008
Abstract In polyamide 12 tube extrusion, calibration is the key step of the process that affects the subsequent mechanical properties. In previous work it has been shown that according to the calibration conditions, a very oriented skin layer may be created, which has been correlated to an important decrease of elongation at break.

Failure criterion for PA12 SLS additive manufactured parts

Additive Manufacturing, 2018
Abstract In order to use selective laser sintering to manufacture structural parts for automotive and aerospace applications, the failure conditions of such a component must be understood and predicted. A 3D failure criterion for anisotropic materials that incorporates stress interactions is implemented to predict failure of selective laser sintered ...

On the Characterization of Wetting and Adhesion in Glass Fiber-PA12 Composites

Journal of Thermoplastic Composite Materials, 2000
A variety of glass fibers (GF) and Polyamide 12 (PA 12) resins were selected to study fiber-matrix wetting and adhesion in thermoplastic composites. The fibers differed in the nature of their surface treatment, the PA 12 resins in their content of amine terminal groups and melt viscosity.

Electrical Properties Investigation in PA12/PANI Composites

Macromolecular Symposia, 2010
AbstractSummary: Volume conducting PA‐12 based composites powders were chemically prepared by in situ polymerization and aniline doping at room temperature. These kinds of polyamide / PANI composites were investigated regarding their electrical properties. Their ac and dc electrical properties measured in the frequency range of 10−2–107 Hz are reported
