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.

This chapter will describe the fundamental aspects and methods for the modeling and simulation of textile reinforcement structures and fiber-reinforced plastic composites (FRPCs). Due to the anisotropic material properties, the simulation of the deformation behavior of textile reinforcement structures is a complex matter. Various approaches will be introduced and simulation solutions based on kinematic models will be discussed in detail. The focus of this chapter is to assist designers and engineers in the design of preforms for complex FRPC components. To correctly configure the composite material according to the expected strains by means of Finite Element Models (FEM), extensive experimental tests for the quantification of composite characteristics are necessary. This contribution will therefore also address modeling and simulation methods based on multi-scale approaches to the determination of special mechanical values of materials.
