Abstract
In this paper, we deals with mechanical performance of resin impregnation with natural fiber and fiber reinforced composites. The effect of the addition of a rein impregnation process on static strength of the injection molded composites was investigated by carrying out tensile and banding tests, followed by Scanning electron microscopy (SEM) observation of fiber surface and fracture surface of composites. The tensile strength of natural fiber and natural fiber reinforced composites with resin impregnation method increases with Polyvinyl alcohol (PVA) impregnation. In addition, Phenol resin impregnation recovers fiber tensile strength after alkali treatment. Resin impregnation causes decrease in contact surface area; however, it does not cause decrease in mechanical properties. Our results suggest that the using rein impregnation method has better effect on the mechanical properties of natural fiber reinforced Polypropylene (PP) composites.

Green composites are alternatives for previously used petroleum base plastics
Untreated Kenaf (UK) and NK have fiber column consists of many vascular bundles and xylem
Polyvinyl alcohol (PVA) and phenol resin impregnated kenaf fiber (PHK) fiber cases were filled up capillary tube with thermosetting resin
Summary
Green composites are alternatives for previously used petroleum base plastics. These plastics were one of the great inventions in human history. Production and use of these plastics may exist primarily due to their cheap cost. It has been known such synthetic plastics cause a high rate of CO2 emissions and require the use of fossil fuel for disposal new, renewable materials must be found. Plant based resources are increasing being harnessed to produce materials that aimed at replacing fossil origin resources.
