Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

open access: yesPolymer Composites, EarlyView.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts

Investigation on Impact Behavior of Thermoplastic Composites: A Ply‐Level Numerical Methodology for Impact‐Resistance Design

open access: yesPolymer Composites, EarlyView.
Experimental and numerical investigation on impact‐tolerance efficient evaluation of soft TPU composites. ABSTRACT This study combines experimental characterization and numerical modeling to investigate the impact behavior of aramid fiber–reinforced composites incorporating a thermoplastic polyurethane (TPU) matrix. Low‐velocity impact (LVI) tests were

Crystallinity, Porosity, and Microstructure of Polyphenylene Sulfide Composite Parts Fabricated by Filament‐Extrusion Additive Manufacturing

open access: yesPolymer Composites, EarlyView.
High‐performance PPS composites for FFF: formulation and characterization linking microstructure and crystallization to adhesion and mechanical properties. ABSTRACT Polyphenylene sulfide (PPS) was compounded with recycled carbon fibers (rCF) and thermal black (TB) particles, followed by injection molding (IM) and extrusion of the compounded composites ...

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

open access: yesphysica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

open access: yesArtificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.

Multi-objective design optimization of polymer spur gears using a hybrid approach

open access: yesJournal of Engineering and Applied Science
Polymer gears are used in applications requiring small to moderate loads to effectively transmit power and use the limited place available as possible. Various commercial standards have been provided designers with the rating criteria and acquaintance of

A Portable Multi‐Parameter Fluid Monitoring Unit for Real‐Time Measurements During Well Development and Geothermal Operations

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Monitoring of fluid parameters during well development, groundwater production, or geothermal operation is essential for the understanding of subsurface and well processes. We developed FluMoMax, a portable fluid monitoring unit, that can measure several physicochemical parameters in real‐time, to monitor fluid characteristics and to enable ...
