Analysis of the Mechanical Properties of Woven Fabrics from Glass and Basalt Yarns
Journal Title: Fibres and Textiles in Eastern Europe - Year 2015, Vol 23, Issue 6
Abstract
Among many other materials for the reinforcement of composites, technical fabrics are increasingly being used for the same purpose, especially from glass and basalt tows, which have good mechanical properties.. During tensile stress these fabrics are elongated in the direction of tensile force, and at the same time they contract crosswise in relation to the action of the tensile force. In this paper the tensile properties of woven fabrics made from glass and basalt yarns were investigated. Measurements were focused on the lateral contraction, according to which Poisson’s ratio can be calculated. For these purposes, an innovative device as an upgrade of the strength tester and samples of fabrics of non-standard shapes (cross and square) were used. Mechanical properties of the yarns from which the fabrics were made were analysed before and after weaving in order to define the impact of weaving on them.

Modeling the Performance of Horizontal Anchor Lines During Fall Arrest
The basic materials used for the construction of anchor lines for personal equipment protection against falls from a height are ropes and textile webbing. During fall arrest, horizontal anchor lines significantly affect...
Finite Element Modeling for the Uni-Axial Tensile Behaviour of Metallic Warp-Knitted Fabric
The finite element analysis method (FEM), for its advantages of lower time and economic costing in predicting the mechanical properties of fabrics, was applied to warp-knitted fabrics. In this paper, two bar warp-knitted...
