The invention discloses a manufacturing method for modification to graft apocynum fiber and the reinforced composite. At first, pre-treatment is carried out to apocynum fiber; then it is grafted with diisocyanate; and then after the grafted apocynum fiber is weaved into fiber beam or fabric, it is compounded with resin; finally reinforced resin matrix composite of apocynum fiber is produced. The method of invention makes short apocynum fiber beam form into continuous long fiber beam. The continuous long fiber beam reinforces resin matrix composite so as to improve the dispersion to structure and performance of short apocynum fiber, improve reinforced effect of apocynum fiber and obtain the composite. The intensity of composite can achieve 200MPa or so. The apocynum fiber takes the place of the glass fiber and enters into the high strength composite area. The application prospect is wide and it is provided with environmental benefit.
