Development of tensile fixture with corrugated structure sheet and estimation of tensile strength of glass fibre fabrics based single face corrugated structure sheet

Abstract

This work aims to reveal the tensile characteristics of Glass Fibre fabrics based single face corrugated Structure Sheet (GFSS) by developing a pressure-adjustable fixture in the machine producing direction of GFSS. In order to set the fixture quick-ready and stable, the effects of several set-up conditions on the tensile behavior of GFSS were investigated. As the set-up condition, a wavy aluminum block fitted to the surface trace, insertion of multiple flexible pins into wave holes, and double-sided tapes attached on the upper/lower surfaces were discussed by changing the number of pins N, and also a few of instant adhesives was dipped on the clamped/pressured zone of GFSS (the reinforced model). Through this study, the followings were revealed. To use multiple polystyrene pins and several pieces of double-sided tapes in the proposed fixture contributes to make the tensile line force stable (as the simple model: without any instant adhesives on the clamped zone). To perform the breakage of liner and wave layers in the area of the gauge span, the reinforced model is usable when choosing N > 1. Investigating the tensile response, the strength (peak maximum line force) and the elongation limit of the liner and wave layers were revealed, respectively. By dipping instant adhesives on the clamping zone when N > 6, the combination resistance of liner and wave braiding structure was actualized.
