Crushing mechanisms of cylindrical winding kenaf fiber reinforced composites

This paper presents the crushing behavior of cylindrical kenaf fiber reinforced composites subjected to axial compressive loading. lack of information available on the study of cylindrical composites fabricated using kenaf yarn fibers where it is wound around the cylindrical mold. there are two important parameters are used during the composite fabrications namely fiber orientations (00,50 and 100) and number of layers (1,2 and 3 layers). these composite tubes are crushed axially and forces versus displacement curves are recorded. then,the specific energy absorptions and force ratios are determined. as expected,increasing the number of layers increased the specific energy absorptions but it is not significantly affected the force ratio even different fiber orientations are used. during progressive collapses,most of the failures mechanisms observe are localized buckling with large wall fragmentations. © 2016 penerbit utm press. all rights reserved.
