Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

Advanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Investigation on the thermal degradation of poly-n-alkyl acrylates and poly-n-alky methacrylates (C1-C12)

, 2005
The thermal degradation of a series of poly-n-alkyl acrylates, from methyl to dodecyl, and poly-n-alkyl methacrylates, from butyl to nonyl, has been studied in isothermal conditions at 400-650 °C using pyrolysis-gas chromatography/mass spectrometry.

Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

Advanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

Anticorrosive Performance of Smart Epoxy Coatings With Poly(urea‐formaldehyde) Microcapsules Filled With 5‐Ethylidene‐2‐norbornene

Advanced Engineering Materials, EarlyView.
PUF/ENB microcapsules were synthesized based on a sequential factorial design and incorporated into an epoxy matrix. Their anticorrosive action, associated with the self‐healing mechanism, demonstrated that the addition of microcapsules to the coating improved anticorrosive performance compared to pure epoxy coatings, particularly when the encapsulate ...

Co-operative degradation in thin films of poly(methyl methacrylate) and poly(ethyleneterephthaiate): a c[methyl methacrylate) and Poly(ethyl( [PDF]

, 2000
The interaction between thin films of polymethyi methacrylate and polyethylene terephthalate is reported. Studies of bulk PET/PMMA blends reveal that a direct ester exchange reaction occurs between the two polymers, and this information is used in the ...
