ARE NATURAL FIBER COMPOSITES ENVIRONMENTALLY SUPERIOR TO GLASS FIBER REINFORCED COMPOSITES?
INTRODUCTION:-
• Natural fibers have been used to reinforce materials for
over 3,000 years.
• Many types of natural fibers have been investigated for
use in plastics .including , Flax, hemp, jute, straw,
wood fiber, rice husks,wheat,barley,oats .
• Natural fibers have the advantage that they are
renewable resources and have marketing appeal.
• Natural fibers are increasingly used in automotive a ....etc

Optical Fiber Communications


1.0 Introduction of Optical Fiber Communications

Our current age of technology is the result of many brilliant inventions and discoveries, but it is our ability to transmit information, and the media we use to do it, that is perhaps most responsible for its evolution. Progressing from the copp cable, our increasing ability to transmit more information, more quickly and over longer distances has expanded the boundaries of our technological development in all areas. ....etc

Microbend optical fiber sensor for high-spatial resolution measurement of strain distribution
Abstract:
A new optical fiber sensor system has been developed for measuring strain distribution. Microbend scattering process is used for the sensing of strain and high spatial resolution of 1m was achieved for both plastic and silica glass fiber. Keywords: Optical fiber sensor, strain distribution, microbending, plastic fiber, silica fiber, geo-textile,
