Hybrid Fiber Amplifier [PDF]

open access: yes, 2012
The advent of telecommunications in 1870s completely revolutionized the world of communications. Metallic cables consisting of twisted wire cables, co-axial cables were the media of choice for many years. These could be used efficiently up to frequencies of 10MHz but the system performance degraded beyond this range. However, with the increasing demand

Performance enhancement of nylon/Kevlar fiber composites through viscoelastically generated pre-stress [PDF]

open access: yes, 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 ...
