MEASUREMENT AND ESTIMATION OF STRAIN RECOVERY ELASTICITY IN NYLON-6 FIBERS

A Study on the Kinetic and Thermodynamic Parameters of Different Acid Dyes on Nylon 6 Fibers

Measurement and Analysis of Green Energy Economy Indicators in Iran (Measurement of Carbon Dioxide Emission and its Elasticity)

Achieving sustainable economic growth is one of the most important goals of countries' economic programs and policies in the current era. Along with economic growth, consumption of energy rises. Since fossil fuels provide a major share of the world's energy, increased fuel consumption is an inevitable feature of economic growth.  Continuation of this trend increases greenhouse gas emmissions, n...

Modification of Nylon 6 , 6 1

Nylon 6, 6 is regarded as tough and ductile materials since it exhibit high tensile elongation to break and high drop weight impact strengths. However, under conditions of stress concentration such as in the presence of sharp notches or cracks, polyamides exhibit brittle failure. This property, evaluated as notched Izod or Charpy impact tests, indicates that unmodified polyamides exhibit relati...

Investigating the Effects of Nanoclay and Nylon Fibers on the Mechanical Properties of Asphalt Concrete

This paper describes the effects of reinforcement by randomly distributed nylon fibers and addition of nanoclay on some engineering properties of a typical asphalt concrete. The properties of asphalt concrete reinforced by different percentages of 25 mm nylon fibers have been compared with those of the mixtures containing different percentages of nanoclay and those in which both the fibers and ...
