Un equipo de investigadores de la Universidad de Pekín ha desarrollado un nuevo material que podría ser el tejido más fuerte jamás fabricado. Este innovador material combina fibras de aramida (el polímero que compone el Kevlar) con nanotubos de carbono alineados a escala molecular. Con solo 1,8 mm d... [Ver más]
Este avance podría cambiar la seguridad militar, buscando más ligereza sin sacrificar protección.
Installing the flaperon on the glider's wing.

It's a full-span flaperon, in two halves. Each half is almost 12 feet long.
Each flaperon half has 8 hinges made of a pintle/gudgeon pair. (1st photo)

When installing the outer flaperon half, I also have to engage two sets of pin/sockets that ensure the two halves move as one unit. (2nd photo) (Each flaperon half is driven by its own flight control linkage, not shown here.)
One of the 8 hinges on each flaperon half also serves as a retainer that handles side loads. (3rd and 4th photos.)
The flaperon halves are intentionally not very stiff longitudinally so that they flex with the wing, but they are much stiffer radially to resist deformation because they are driven at only one point by the flight control linkage. This feature is fairly easy to achieve in composite fabrication because you can orient the fabric fibers in certain directions. In this case we used Kevlar, not carbon or fiberglass.)

Two men in the Houston area took turns shooting each other earlier this month while wearing a ballistics helmet, according to Harris County Sheriff Ed Gonzalez, who said the incident led to the death of one of them and murder charges for the other.

Sean Odonnell, 37, was arrested and charged with murder Thursday in the shooting death of Aaron Prout, a 34-year-old man from the United Kingdom who resided in Harris County, Sheriff Ed Gonzalez wrote in a social media post. The sheriff says they shot each other inside a home while "wearing a kevlar helmet."
Made a bracelet that easily deploys 10 yards of kevlar cord (1.5 mm, 300 lbs tensile strength). I've shared a Paracord version before, but kevlar is thinner, stronger, and can be used as a friction saw!
