Title : 3D HEMISPHERE PRESSURE CLAMPED TEST ON STITCHING PLAIN WOVEN KENAF FABRIC

Abstract :

In recent years, the natural fibre such as kenaf fibre have been studied extensively. In this study, an experimental investigation was conducted to explore the effect of stitching technique of plain woven kenaf fabric on 3D hemisphere pressure clamped test. There were eight types of stitching patterns applied to the kenaf fabric. These patterns were divided into two categories that were single and double stitch patterns. Single stitching includes Vertical, Horizontal, Tilt 30° and Tilt 60°. Double stitching includes Box, Tilt 45°/90°, Tilt 30°/30° and Tilt 60°/60°. The radius of the hemispheric punch was 40 mm and the compression hemisphere displacement was fixed to the woven kenaf fabric by 40 mm. The clamps were placed on the plane plate, where the pressure was transformed from the hemisphere punch to the specified position on the stitching fabric with two supporting clamping tools. Box stitched pattern was found to indicate the highest compressive load of about 1.43 kN compared to other stitching patterns. Double stitching has a significant effect on 3D hemisphere pressure clamped test performance which enables an average improvement of 50 percent above the unstitched sample. This is due to the double cross stitch of the design of the box, the stress is distributed equally at 90° and 0°In recent years, the natural fibre such as kenaf fibre have been studied extensively.
