The main objective of this paper is to study the impact strength and moisture absorption properties of long fiber and short fiber hybrid composites using a kenaf/polyethylene terephthalate fiber reinforced in the polyoxymethylene matrix. The results obtained from the impact test gave 10.8 J/cm for the longer fiber hybrid composites, which is higher compared to 8.0 J/cm obtained for the short fiber hybrid composites due to less fiber pullout from the matrix. A moisture content of 0.92 and percentage water absorption of 6.77 were obtained for the long fiber composite due to poor interfacial adhesion between the fiber and the matrix. A high void content of 0.52 and porosity of 1.21 also accounted for high water and moisture absorption of the long fiber hybrid composite.
