Method Of Production

The following paper presents a simple, inexpensive and scalable method of production of carbon nanotube-polyurethane elastomer composite. The new method enables the formation of fibers with 40% w/w of nanotubes in a polymer. Thanks to the 8 times higher content of nanotubes than previously reported for such composites, over an order of magnitude higher electrical conductivity is also observed. The composite fibers are highly elastic and both their electrical and mechanical properties may be easily controlled by changing the nanotubes content in the composite. It is shown that these composite fibers may be easily integrated with traditional textiles by sewing or ironing. However, taking into account their light-weight, high conductivity, flexibility and easiness of molding it may be expected that their potential applications are not limited to the smart textiles industry.

Acceleration Test

The purpose of the study is to reduce the damage of the soldier boots, which subject the blast load. The boot sole was reinforced to perform the study. Thermoplastic polyurethane (TPU) and multi-walled carbon nanotube (MWCNT) materials were used for this reinforcement. In addition, TPU 508 material was used as energy absorber, and Carbon-Kevlar fiber composite was utilized to decrease the impact effect of blast load. Acceleration test system was used to simulate the blast load. Three different boots were used in the study (ordinary boot, semi-damped boot, and fully damped boot). Twin-screw extruder was used to blend melted material to prepare polyurethane MWCNT with weight fraction from 1% to 5%. In addition, mechanical properties of these materials were obtained by tensile tests. The best mechanical properties were obtained with the weight fraction of 1% MWCNT. Acceleration test was applied to measure the energy damping performance of new designed boot sole. As a result of the study, the best reduction on the blast load was obtained nearly 12% with the fully damped soldier boot.
