Rigidity of Glass, Carbon, and Organic Yarns of Special-Purpose Fabrics

Abstract

The results of experimental determination of rigidity of glass, carbon, and organic yarns are reported. It is shown that glass yarn, from which triaxial Armaton TKh 700 fabric is made, has the highest coefficient of rigidity and organic yarn, from which SHM fabric is made, has the lowest coefficient of rigidity. The rigidity coefficients of EE380 and EE106 fabrics, which are very close in glass fibre composition, differ by more than 70%. All glass fibres are close to each other in expansion angle values. Expansion angle of carbon fibres is smaller than that of glass fibres, and organic fibres have the smallest expansion angles, which indicate that the latter are least creasy.
