This paper presented the mechanical and fatigue behavior of woven kenaf fiber reinforced epoxy composites with the composition of 16.67% kenaf and 83.33% of epoxy (1:5 weight ratio) with 1% of silica aerogel. Hand lay-up technique was used to prepare the specimens. Fatigue test was conducted at constant stress amplitude, 5 Hz frequency, 0.5 stress ratios and the maximum stress applied was from 90 % to 70 % of ultimate tensile strength (UTS) with decrement of 5%. From the results, tensile properties and fatigue life improved as silica aerogel is added into the composite.
