Kevlar uses very tightly woven polymer threads each of which has an inherently high tensile strength to provide protection. What you end up with is a material that can "catch" high velocity objects in the fibers without distorting much. As a bonus, the material is durable stuff and doesn't abrade easily. It will however transfer energy beyond the fabric, and that is why police who have been shot while wearing Kevlar still get massive bruising and broken bones. So by itself Kevlar will not do much good for blunt impacts like smacking your elbow on the pavement at 100mph.
So no, Kevlar doesn't work like the material in the article. Just my humble opinion.
