The objective of this research is to understand more fully the out‐of‐plane auxetic behavior of paper. In the reported research, initial characterization of the auxetic properties of common, commercially available papers is described. The results of these experiments suggest that the auxetic response seen in paper structures is related to the cellulose fiber network structure, as previously suggested, and is related to inter‐fiber bonding and fiber organization in the sheet. These results also… 

Stiffness of Synclastic Wood‐Based Auxetic Sandwich Panels

Auxeticity of materials improves several of their mechanical properties, especially shear, impact, and bending resistance. It also improves ability of materials to absorb impact energy as well as the

What are the ranges and basis of auxeticity in the phases of cellulose microfibrils

The 1D bundles of cellulose microfibrils (lignified flax fibre) and 2D networks of cellulose microfibrils from tunicate, bacterial and microfibrillated celluloses were strained in tension, and their

Development of a Biomedical Neckbrace through Tailored Auxetic Shapes

The knowledge acquired about novel auxetic structures has been applied to the development of an innovative neckbrace for orthopaedic purposes, which is comfortable, in that it is flexible, resistant, anatomical and transpiring.

Induction of auxetic response in needle‐punched nonwovens: Effects of temperature, pressure, and time

We have examined the effect of temperature, pressure, and time on the magnitude of induced auxetic response in post‐manufacture‐processed needle‐punched nonwovens. Different combinations of these

Inducing out‐of‐plane auxetic behavior in needle‐punched nonwovens

We describe here a heat‐compression protocol used on needle‐punched commercial nonwoven fabrics which induces an out‐of‐plane auxetic response in these treated fabrics. The as‐received samples,

Mathematical modeling of auxetic systems: bridging the gap between analytical models and observation

The Poisson’s ratio, a property which quantifies the changes in thickness when a material is stretched and compressed, can be determined as the negative of the transverse strain over the applied

Creating three-dimensional (3D) fiber networks with out-of-plane auxetic behavior over large deformations

Fiber networks with out-of-plane auxetic behavior have been sporadically investigated. One of the major challenges is to design such materials with giant negative Poisson’s ratio over large

Electromechanical coupling of isotropic fibrous networks with tailored auxetic behavior induced by water-printing under tension

Understanding the electromechanical coupling of auxetic materials offers unique opportunities to enhance the sensitivity of piezoresistive sensors. Reports on the auxetic behavior of random fiber

Modeling of negative Poisson’s ratio (auxetic) crystalline cellulose Iβ

Energy minimizations for unstretched and stretched cellulose models using an all-atom empirical force field (molecular mechanics) have been performed to investigate the mechanism for auxetic

3D Strain Field Evolution and Failure Mechanisms in Anisotropic Paperboard

Experimental analyses of the 3D strain field evolution during loading allows for better understanding of deformation and failure mechanisms at the meso- and microscale in different materials. In



Modeling the auxetic transition for carbon nanotube sheets

A simple model is developed to predict the complex mechanical properties of carbon nanotube sheets (buckypaper) [Hall et al., Science 320 504 (2008)]. Fabricated using a similar method to that

How to make auxetic fibre reinforced composites

Auxetic composite materials can be produced either from conventional components via specially designed configurations or from auxetic components. This paper reviews manufacturing methods for both

Modelling the negative Poisson's ratio of compressed fused fibre networks

Examples of auxetic fused fibrous assemblies can be found among both natural and synthetic materials. In theory, fibrous network materials can exhibit negative Poisson's ratios, yet the deformation

On Modeling Bonds in Fused, Porous Networks: 3D Simulations of Fibrous–Particulate Joints

The deformation and failure of fused, porous networks are key concerns in microscale power sources and open trusses for structural applications. We have found that the behavior of the connection

Effective Young's modulus of bacterial and microfibrillated cellulose fibrils in fibrous networks.

Experimental data and theoretical analysis shows that the Raman band shift rate arising from deformation of networks under tension is dependent on the angles between the axis of fibrils, the strain axis, the incident laser polarization direction, and the back scattered polarization configurations.

Sign Change of Poisson's Ratio for Carbon Nanotube Sheets

It is found that the in-plane Poisson's ratio of carbon nanotube sheets (buckypaper) can be tuned from positive to negative by mixing single-walled and multiwalled nanotubes, and density-normalized sheet toughness, strength, and modulus were substantially increased by this mixing.
