Multifunctional nanofiber protects against explosions

This article took me a few reads through to get the idea, but here's what I think I have. I'll use quotes from the article...

"[T]he researchers needed to explore the tradeoff between mechanical protection and thermal insulation, properties rooted in a material's molecular structure and orientation."

"Materials with strong mechanical protection, such as metals and ceramics, have a highly ordered and aligned molecular structure. ... Insulating materials, on the other hand, have a much less ordered structure, which prevents the transmission of heat through the material."

" "Our idea was to use this Kevlar polymer to combine the woven, ordered structure of fibers with the porosity of aerogels to make long, continuous fibers with porous spacing in between," said Gonzalez. "In this system, the long fibers could resist a mechanical impact while the pores would limit heat diffusion." "

"[T]he researchers were able to spin long, aligned nanofibers into porous sheets—providing enough order to protect against projectiles but enough disorder to protect against heat."

First off, whoa, there's such a thing as kevlar aerogel?

And B, I think I might need to re-read the article because I kind of went away thinking about what the heck a kevlar aerogel would be.
