The Specific Tensile Strength of Triaxial Fabrics

Abstract

In this study the tensile testing was made as a function of direction for the triaxial fabrics with 48 yarns made by a braiding machine. In the testing, the specimens with different directions from the machine direction were taken out and provided the measurements of the load-elongation curves in the light load.The results were compared with those of the arthogonal fabrics.The following conclusions are obtained:1) The cover factor of triaxial fabrics is shown as; then d=60 and C=67%. 2) The ratio (n) of the specimen length to chack width and the angle 0 between the axis and yarn are varied, the number of kinds of yarns holding both ends is varied between Q--3, as shown in Fig. 5.3) When experiments are made at n = 1, triaxial fabrics have less directional properties with regard to the load-elongation than orthogonal fabrics.
