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 ...
