Ultrasound‐Assisted Epoxy Resin Curing Monitored by Impedance Spectroscopy

Polymer Engineering &Science, EarlyView.
Ultrasound enhances epoxy cure rates via localized heating without altering cure kinetics. Impedance spectroscopy provides a direct, non‐destructive measure of cure progression, enabling accurate mapping of degree of cure in real time. ABSTRACT Epoxy resins are widely used in aerospace and automotive manufacturing as structural adhesives and matrices ...

Effect of Accelerated Aging on the Performances of 3D Printed Polylactic Acid‐Polyhydroxyalkanoate Specimens

Polymer Engineering &Science, EarlyView.
The accelerated aging behaviours on the FFF‐fabricated PLA‐PHA Specimens. ABSTRACT Despite the increasing use of biodegradable polymers in additive manufacturing, their long‐term durability remains insufficiently understood. The aim of this study to investigate the influence of accelerated aging on the performance of fused filament fabrication‐printed ...

Unmanned Aerial Systems for Corrosion Detection: Multi‐Sensor Technologies, Challenges, and Opportunities for Next‐Generation Inspection

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.
