This chapter discusses the complex interaction between fabric architecture, coating, and mechanical response. A brief introduction to fabrics and test methods is provided. Picture frame experimental studies and modeling studies are used to explore the effect of yarn mobility (i.e., fabric weave pattern, yarn size and spacing, and coating penetration) on shear behavior. Similarly, trouser tear experiments demonstrate the effect of del zone yarn mobility on tear strength. Finally, more representative coated fabric finite element models are addressed through discussion of distinctive factors such as crimp effect, locking angle, and coating adhesion.
