Effects of Defects on the Performance of Hierarchical Honeycomb Metamaterials Realized Through Additive Manufacturing
… the structural organization of cellular structures leads to new metamaterials with superior properties providing lightweight and very strong/stiff structures. The incorporation of hierarchy to regular cellular structures enhances the properties and introduces novel tailorable …

Analytical and experimental study of FRP honeycomb sandwich panels with sinusoidal core
… reinforced plastic (FRP) composite materials and structures have been increasingly used in highway bridge applications. Recent applications have demonstrated that FRP honeycomb sandwich panels with sinusoidal core can be effectively and economically used for highway bridge deck systems. In this …

Development of Stochastic and Anisotropic Multiscale Ceramics Using High Aspect Ratio Sacrificial Fillers
… is a specific emphasis on creating anisotropic structures via a directional ice-templating technique and hard-templating using the sacrificial filler method. Cellulose nanocrystals (CNCs) aerogels have been created via a ceramic suspension of 100g/mL of CNC powder and deionized water. Samples …

Failure of sandwich honeycomb panels in bending
… a predominant failure mechanism for thin gauge honeycomb sandwich panels loaded in bending or compression. Over the past 60 years, considerable work has been devoted to understanding wrinkling and trying to predict failure loads in damaged and undamaged panels accurately. Existing wrinkling …

From clay slurries to mudrocks : a cryo-SEM investigation of the development of the porosity and microstructure
… widely accepted models for clay slurries, the honeycomb structure, is an artifact of the plunge-freezing method and does not reflect the in-situ structure. In the field of geological sciences, this contrasts a fundamental view of fabric evolution that has inferred the presence of honeycomb …

Synthesis and Characterization of Functional Biodegradable Polyesters
… process. Highly ordered microporous honeycomb structures were developed on photo-functional star-shaped PDLLA surfaces. The pore dimensions were dependent on polymer solution concentration, polymer molar mass and relative humidity. The combination of self-organizing and cross-linking …
