Effects of Surface Modification on Mechanical Properties of Sisal Fiber Reinforced Polypropylene Composites

In order to improve the adhesiveness between sisal fiber and polypropylene,several methods of surface modification were studied.Scanning electron microscopy,infrared spectrum and X-ray diffraction were used to observe the difference after modification.The results show that surface modification can effectively increase the adhesiveness and thus improre the mechanical behavior of composites.
