This research focuses on the reinforcement of Kevlar in treated kenaf composite,
specifically in the study of impact properties as well as the characteristics. The kenaf was
treated with 6% Sodium Hydroxide (NaOH) solution at a specific period of time before
being made into laminates. Impact test was conducted using an instrumented drop
tower device at 36J level according to the standard ASTM D7136. Microstructures of the
fractured specimens were also analyzed. The results of the study indicated that treated
kenaf/Kevlar hybrid composite has better impact absorption energy than pure kenaf
composite. Compared to the pure kenaf composite, the hybrid composite absorbs more
impact energy and appears to have lower impact damage at the same impact energy
level. This is because the Kevlar fibres play an important role to prevent and delay the
destruction of composites.
