Features of quasistatic tests of threads and fabrics

This paper devoted to analyzes the methodological issues of mechanical testing of filaments and fabrics, which are the reinforcing elements to create composite materials. In this paper static tensile tests techniques silica fabric CT-11-TOA and glass filaments with determination of mechanical properties develop and approved. On samples of fabric value of the maximum ultimate load is defined, the statistical analysis is carried out, the variation coefficient is counted, deformation charts are constructed. On samples of glass threads values of the maximum loading, the maximum specific loading, the elastic module and relative elongation at a gap. The diagrams of deformation carried out statistical analysis of 60 samples were obtained and the average values of the mechanical characteristics and the coefficients of variation. Tests were carried out on the electromechanical Instron 5965 testing system with use of the contactless video extensometer AVE.
