Performance enhancement of nylon/Kevlar fiber composites through viscoelastically generated pre-stress [PDF]
, 2013 Kevlar-29 fibers have high strength and stiffness but nylon 6,6 fibers have greater ductility. Thus by commingling these fibers prior to molding in a resin, the resulting hybrid composite may be mechanically superior to the corresponding single fiber ...
