Motorola DROID Turbo - Kevlar vs ballistic nylon | …

12-11-2014· Beau HD reviews the design of the two Motorola DROID Turbo variants. The red Kevlar back cover is flashy and stylish but doesn't feel quite as premium in the hands due to it being plastic in nature. The black ballistic nylon version is certainly the better feeling version of the two as it features a very unique ballistic nylon pattern on the back that is textured to provide additional grip.

polymers - Why isn't nylon as strong as kevlar ...

01-05-2019· $\begingroup$ "Strong" is an ambiguous term here. nylon is strong in the sense that it is hard to break (but is very easy to stretch and deform). Kevlar is also hard to break but is also much more rigid and harder to deform. Stiffness and "strength" are not the same and Kevlar is useful because it has both. $\endgroup$ – matt_black May 1 '19 at 13:24
