Knot strength investigation of braided glass filament fiber sewing threads
Source abstract
Abstract
Two-dimensional braided sewing thread made of glass fiber was tailored to conquer the rupture problem of the glass tow in stitching process of composite preform or prepreg.Instron apparatus was used to test the tensile strength of the knot and loop of specimens with different braiding parameters,and the breaking mechanism and rupture mode were analyzed.The results showed that 2-D braided glass fiber thread had better breaking tenacity and elongation than the glass tow.The knot performance was mainly influenced by pitch length.Shear and tensile force were acted on the specimens jointly during the test that made the thread undergo three phases: unwinding,force bearing and breaking.And the broken end was seen nearly flush.
