Effect of yarn twist on mechanical properties of glass fibre reinforced composite rods

摘要

Effect of twist of glass yarns on the tensile, flexural and interfacial shear properties of composites has been studied. The glass fibre reinforced composite rods have been prepared by hand pultrusion technique with various twist levels. It is found that with the increase in twist level in yarns, the tensile, flexural and interfacial shear strength properties of the composites increase upto 0.25 TPI, 1.0 TPI and 0.75 TPI respectively, followed by decrease in the properties of the composites.
