Monitoring the effects of impact damages on modal parameters in carbon fiber entangled sandwich beams [PDF]

open access: yes, 2009
The aim is to study the impact toughness of two types of entangled sandwich materials (heavy and light) with the help of vibration testing. A simple case of symmetrical impacts is studied in this article as no literature is available regarding impact ...

Sub‐nm2 Ferroelectric Domains via Charged 180° Walls in ZrO2

open access: yesAdvanced Materials, EarlyView.
Ferroelectric ZrO2${\rm ZrO}_2$ thin films host closely spaced charged 180∘$^{\circ }$ domain walls that vertically compress polar domains beyond their lateral half‐unit‐cell limit. These head‐to‐head and tail‐to‐tail walls show distinct bulk‐like structures, natural oxygen‐mediated stabilization, and highly asymmetric mobility, highlighting new ...

Sandwich Structured Composites for Aeronautics: Methods of Manufacturing Affecting Some Mechanical Properties

open access: yesInternational Journal of Aerospace Engineering, 2016
Sandwich panels are composites which consist of two thin laminate outer skins and lightweight (e.g., honeycomb) thick core structure. Owing to the core structure, such composites are distinguished by stiffness. Despite the thickness of the core, sandwich

Characteristics of Innovative 3-D FRP Sandwich Panels

open access: yes, 2006
Foam and honeycomb core sandwich composites are widely used in structural applications. Nevertheless, possibilities of core-to-face sheet delamination, crushing and buckling instability are major concerns. This study presents an innovative system for FRP

Percolation‐Driven β‐Relaxation Enables Resonant Acceleration of Crystallization in Amorphous Phase‐Change Materials

open access: yesAdvanced Materials, EarlyView.
Mobile‐atom percolation underlying β‐relaxations fundamentally dictates the crystallization pathways of phase‐change materials. High‐frequency ultrasonic excitation dynamically modulates this critical mobility percolation network, substantially accelerating the crystallization process.

Prediction of screw withdrawal resistance for plywood laminated panels and sandwich panels

open access: yesTurkish Journal of Forestry
Sandwich panels are favorable materials for structural or non-structural components due to durability, lightness, and longevity in service life. This study aimed to predict screw withdrawal resistance of the plywood laminated medium-density fiberboard ...

Bridging Biosensing and Hardware‐Level Data Security With a Conjugated Radical Polymer

open access: yesAdvanced Materials, EarlyView.
A conjugated radical polymer provides two complementary functions within a common material platform: sensitive dopamine biosensing and device‐specific stochastic electrical responses for security. The work demonstrates a materials‐based approach for combining bioelectronic signal acquisition with hardware‐level authentication while maintaining the ...

Conformal Coating and Transfer of 2D Nanomaterials via Dynamic Interface Engineering

open access: yesAdvanced Materials Interfaces, EarlyView.
This review discusses conformal coating and transfer of two‐dimensional (2D) nanomaterials with a focus on dynamic interface engineering. By actively regulating nanosheet transport and interfacial contact during film formation, recent dynamic coating strategies overcome the limitations of conventional passive approaches and enable geometry‐adaptive ...
