Knitted Meshes for Reinforcing Building Composites

A computational study of knitted Nitinol meshes for their prospective use as external vein reinforcement.

External reinforcement has been suggested for autologous vein grafts to address the mismatch of mechanical properties and fluid dynamics of graft and host vessel, a main factor for graft failure. A finite-element tool was developed to investigate the mechanical behaviour, in particular radial compliance, of knitted Nitinol meshes (internal diameter: 3.34 mm) with two different knit designs (eve...

Numerical Estimation of the Mechanical Properties of CNT- reinforcing Composites

Carbon nanotubes (CNTs) possess excellent mechanical properties, such as high stiffness, strength, resilience etc., and may become an ideal reinforcing material for the development of nanocomposites. In this paper, we establish a finite element model of the volume representative element (RVE) for CNT-reinforcing composites and evaluate their mechanical properties based on the Equivalent Homogen...

Knitted nitinol represents a new generation of constrictive external vein graft meshes.

OBJECTIVE Constriction of vein grafts with braided external nitinol meshes had previously led to the successful elimination of neointimal tissue formation. We investigated whether pulse compliance, smaller kink-free bending radius, and milder medial atrophy can be achieved by knitting the meshes rather than braiding, without losing the suppressive effect on intimal hyperplasia. METHODS Pulse ...

Effect of fiber densities on impact properties of biaxial warp-knitted textile composites

In this study, an appropriate fabric weight content controlled by the density of the warp and weft fibers is determined for biaxial warp-knitted composites referring to mechanical test results. Six different types of composite panel with two different fabric weights (813 and 1187 gr/m) and with three different stacking sequences [90we/0wa/90we/0wa]s, [90wa/ 0we/90wa/0we]s, and [90wa/0we/90we/0w...
