Kevlar doesn't melt, it "decomposes" just shy of 500 degrees C.

It doesn't burn either unless you hold a blow torch to it.
The outer shell of a vest however is another story depending on what it's made of.
Silicon Carbide, which is the ceramic used in vests likewise will not melt. Another use for it is disk brakes in high performance vehicles where melting at any temperature would be squarely in the "bad things" category.
