Analysis of Woven Fabric Strengths: Prediction of Fabric Strength under Uniaxial and Biaxial Extensions

This study of woven fabric strength begins by focusing on the effects of the crossing points, where warp and weft yarns interlace with each other to form a fabric, towards the ultimate fabric tensile strength. When a fabric is under uniaxial or biaxial tension, the yarn-yarn interactions at the crossing points are found to consist of two components, a pressure-independent adhesive component and...

-plasma Treatment on Woven Plain Polyester Fabric in Adjusting Hydrophilicity

Hydrophilisation of polyester textile materials has been investigated over the last twenty years using low-pressure and atmospheric plasmas. According to these studies, wettability and capillarity of fabrics can be significantly improved depending on the process gas used. In the present study, the effects of low pressure O 2 and NH 3 plasma on the morphology and topometry of fabrics on four dif...

Characterization of fabric tensile loading curve in nonlinear region related to their structure; Part1: woven fabric

Influence of the Dry Woven Fabrics Meso-structure on Fabric/fabric Contact Behaviour

The first stage of the RTM process concerns the preforming of the part. During the preforming of multilayered reinforcements, frictions between the plies occur. An experimental device designed to analyse the ply/ply, ply/tool and yarn/yarn frictions has been set up. Specific contact behaviour for ply/ply friction is directly related to shocks taking place between overhanging yarns of each sampl...

Effect of Strain Rate on the Tensile Failure of Woven Reinforced Polyester Resin Composites

Tensile stress-strain curves a r e obtained at s t rain rates of %lo-'+, ~ 1 0 and c1000/s for carbon, Kevlar and glass fibre woven-reinforced polyester resin compos i tes and the variation of modulus, tensile strength and fracture strain with strain rate is determined. A change in the failure mode at the highest strain rates is observed for the glass but not the carbon or Kevlar reinforced com...
