【Abstract】 Composite based on polypropylene(PP) and sisal fiber(SF) containing oxidized polyethylene wax(OPE) is prepared by melt mixing and injection molding.The mechanical behaviours of the PP/OPE/SF composite are systematically investigated.The results show that the izod impact strength of the composite is evidently elevated after OPE is added into PP/SF system.On the other hand,the proper amount of OPE enhances the interfacial interaction between the reinforcing SF and PP matrix.It leads to the improvement in tensile strength and modulus of the composite.更多还原
