The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

Polymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...

Simulation of the Rotational Molding Process of Polyethylene Using the Smoothed Particle Hydrodynamics Method

Polymer Engineering &Science, EarlyView.
Numerical simulation of polyethylene rotational molding using the Smoothed Particle Hydrodynamics (SPH) method. ABSTRACT This work presents the development of a numerical model based on the smoothed particle hydrodynamics (SPH) method to simulate the rotational molding process of powder thermoplastic polymers, used in the manufacture of liners for high‐

Single Versus Double Screw Extrusion: Impact on Mechanical Performance and Crack Resistance for a Virgin, Recycled, and Blended Polypropylene

Polymer Engineering &Science, EarlyView.
Schematic overview of the study approach and key findings. ABSTRACT To evaluate the influence of extrusion on material performance, three processing methods, single extrusion (1x Ex), double extrusion (2x Ex), and double screw compounding (C), were investigated for virgin polypropylene (vPP), recycled PP (rPP), and a blend containing 10% rPP (rPP10 ...

Friction‐Corrected In‐Situ Viscosity Measurement in Material Extrusion: A Force‐Based Method Validated Against Capillary Rheometry Using Identical Nozzle Geometry

Polymer Engineering &Science, EarlyView.
In the filament force measurement (FFM), the friction of the solid filament, determined in an open‐bore reference, is subtracted from the measured extrusion force to obtain the capillary force. The resulting apparent viscosity is compared with high‐pressure capillary rheometry (HPCR) using the identical printer nozzle in both instruments.
