| Summary: | 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. |
