Ultrasound‐Assisted Epoxy Resin Curing Monitored by Impedance Spectroscopy

open access: yesPolymer 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 ...

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

open access: yesPolymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

Structural characterization and optimum machining parameters of jute/carbon fibre hybrid reinforced epoxy composite laminates

open access: yesPolymer International, EarlyView.
Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

EBI-strengthening of CFRP

open access: yesJournal of Advanced Science, 2006
Carbon fiber reinforced (CFRPs) are increasingly commonly used composite materials based on carbon faiber. To evaluate the strength was used the tensile test, bending test and Carpy impact Test. We concluded that EB irradiation reinforced mechanical properties for CFPRP.

Performance evaluation of thick carbon fiber‐reinforced laminates manufactured using six‐magnetron microwave system

open access: yesPolymer International, EarlyView.
IM7/Cycom 5320‐1 unidirectional prepreg has been used to fabricate 64‐layer laminated composites. A custom‐built six‐magnetron microwave applicator and an autoclave were employed to manufacture the composite panels. Mechanical performance of the microwave‐cured composites has been juxtaposed to autoclave‐cured composites in terms of uniaxial tensile ...
