| Summary: | This present work investigated the perforated impact strength of woven kenaf fiber
reinforced composites subjected to different projectile velocities. Three layers of woven kenaf mats
were stacked with four different fiber orientations 0, 15, 30 and 450. The composites are fabricated
using hand-layout where the woven mats were placed into the mould with a polymeric resin. The
wetted composites were compressed to squeeze out the excessive resin and to eliminate the void
contents. The hardened samples were shaped into a standard geometry specified by ASTM D3763.
Then, the composites were perforated impact using different speeds 1, 2 and 3 m/s. According to
the present results, it was found that the perforated impact strength reduced when the impact
velocity was increased. However, the impact strength of 150 oriented composite was higher when
compared with other types of composites |
