Acrylonitrile Styrene Acrylate (ASA) With Optimized Aluminum Oxide (Al2O3) Nanofiller Content for MEX Additive Manufacturing: Thermomechanical, Rheological, and Quality Metrics

open access: yesPolymer Composites, EarlyView.
Characterization processes for ASA/Al2O3 nanocomposites in MEX 3D printing. ABSTRACT As additive manufacturing (AM) continues to expand, the demand for durable components for outdoor applications is increasing. Acrylonitrile styrene acrylate (ASA), a weather‐resistant polymer, is widely used in these applications, and improving its performance could ...

Additive Manufacturing of Glass Fiber‐Reinforced Polypropylene and Its Behavior Under Controlled Hydrogen Exposure

open access: yesPolymer Composites, EarlyView.
Experimental and numerical assessment of GFRPP under lower experimental hydrogen pressures using tensile testing, SEM analysis, and hydrogen uptake estimation. ABSTRACT Glass fiber‐reinforced polypropylene (GFRPP) composites are increasingly explored for hydrogen transport and storage due to their lightweight nature and corrosion resistance.

Mechanical and Impact Response of Adhesively Bonded ASA/PA12 Sandwich Structures Produced by Fused Filament Fabrication

open access: yesPolymer Engineering &Science, EarlyView.
Adhesively bonded ASA/PA12 FFF sandwich structures reveal that interfacial compliance governs mechanical performance. Cyanoacrylate enhances strength but induces brittle failure, while polyurethane improves ductility and impact resistance, demonstrating that adhesive properties and stacking sequence are critical design parameters for optimizing multi ...

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

open access: yesPolymer 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‐

Improving Welding Behavior of ETPU Bead Foams by Surface Modification with Plasticizers

open access: yesJournal of Polymer Science, EarlyView.
Tributyl citrate (TBC) and stearic acid (SA) modify ETPU beads through different diffusion mechanisms. TBC diffuses the bead structure directly after coating, whereas SA remains on the surface until melting and subsequent diffusion during heating. The resulting plasticization improves bead fusion, allowing RF processing at reduced temperature and ...

Design and Development of a Modular Ballistic Pendulum for High‐Impulse Measurement in Contact and Near‐Field Explosive Loading

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.
