This chapter depicts the advantages and drawbacks of knits as composite reinforcements and gives a nonexhaustive overview of some properties and applications. First, the knitting process capabilities are described, focusing on the opportunity given to knit net-shape 3D preforms with holes and various local properties. Then, the main characteristics of knit permeability are discussed. Finally, the mechanical behavior of dry knits and knit-reinforced composites are investigated. The improvement of the composite mechanical properties by adding inlaid yarns is particularly emphasized, from both experimental and modeling points of view.
