Crosslinked Continuous Glass Fiber-Reinforced Toughened Polypropylene Composites

The authors prepared crosslinkable toughened polypropylene to be used for simultaneous spinning of hybrid yarn and the preparation of continuous glass fiber-reinforced polypropylene composites by filament winding to be consolidated by compression molding. A subsequent electron treatment aims on crosslinking of matrix as well as enhancement of interfacial adhesion in the interphase of glass fiber-reinforced polypropylene composites. The authors evaluate the crosslinking behavior as well as the tensile properties of crosslinkable toughened polypropylene. Finally, the authors use transverse tensile test and single fiber pull-out test in order to study the effect of matrix modification and electron treatment on continuous glass fiber-reinforced polypropylene composites as well as on single glass fiber polypropylene model microcomposites.
