A new type of Negative Poisson's ratio skeleton composites (NPRSC) filled with shear
stiffening gels (SSG) is presented in this work. The skeleton is manufactured by Kirigami …

In this work, an experiment according to the full factorial method (FFM) to investigate the
effect of initial helical angle of wrap component, diameter ratio of components and modulus …

Studies on designing polymeric fibres based helical auxetic yarn (HAY) to maximise their
auxetic effect are yet to propose optimised design configurations for general impact …

Textile structures with negative Poisson's ratio (PR) behavior are called auxetic textile
structures. They have received increasing attention in recent years and have been designed …

An auxetic braided structure was developed in our previous work for overcoming the
slippage problem encountered in the double-helix yarn. However, the influences of the …

Helical auxetic yarn is a structural material with negative Poisson's ratio which contains a
soft yarn with a higher diameter as a core component and a stiff yarn with a lower diameter …

This paper presents an experimental study of tensile and deformation behavior of an auxetic
plied yarn structure. The basic configuration of the plied structure formed with two soft yarns …

The negative Poisson's ratio fiber reinforced concrete (NPR-FRC) was prepared using a
new type of negative Poisson's ratio fiber (NPRF), with PVA fiber as the core and carbon …

In this paper, we report a new multi-scale NPR composite based on auxetic fabric/elastomer
matrix (AF/EM) composite structure. The multi-scale AF was obtained via using helical …

Helical auxetic yarns (HAYs) spun by ring spinning have a large residual torque, which
restricts their application. To address this problem, the hollow-spindle covering system was …
