A significant effect of the yarn tension and the contact shear stresses on the defect occurrence was demonstrated.
Most conventional "two-dimensional" (2D) knitted fabrics contain a significant proportion of their yarns in the thickness direction of the fabric.
From the results it could be found that the glass transition temperatures of epoxy resin and carbon fiber yarns had significant effects on the thermal expansion behaviors of plain woven composites.
While friction improves ballistic performance by maintaining the integrity of the weave pattern, material properties of the yarns have a significant influence on the effect of friction.
Although mechanical properties of CNT yarns exhibited a significant statistical variation, the resistance was found to have much less statistical variation making them good candidates as sensors for structural health monitoring in composites.
For eastern redcedar yarns exposed to laundering, the difference between mordanted and nonmordanted was significant such that nonmordanted (ΔE = 2.35) yarns had improved colorfastness to laundering over mordanted (ΔE = 3.83) conditions; t(16) = −4.80, p = 0.000.
However, 3D woven composites feature more complex textile architecture then 2D woven materials, and in reality nominally straight warp and weft yarns can also possess significant waviness.
Our nanofiber yarn-based biotextiles have significant potential to be used as engineered scaffolds to synergize the multiple cell interaction and mechanical stimulation for promoting tendon regeneration.
The sisters' most significant new find is several balls of bright red yarn, which they gleefully take home, leaving a yarn trail in their wake that evokes Hansel and Gretel's bread crumbs.
One of examples is micro-buckling of fibres in yarns under compressive loading, which plays a significant role in the global behaviour of braided composite structures.
