Tetrakevlar is the evolution of a compound invented in the 20th century, primarily designed to stop kinetic projectiles. The latest innovation (Tetrakevlar XIX) incorporates Biosteel into its formula, giving it enhanced protection against slashing weapons.
Single-layer tetrakevlar can look like any ordinary cloth, but you'll have one hell of a time trying to cut, tear, burn, or puncture it. It is made of a weave of advanced synthetic and biological polymers that have the greatest tensile strengths known in the universe. Cheaply auto-assembled by nanobots, most clothing in the galaxy worn by spacefarers is actually some form of tetrakevlar. While it will absorb and spread out small impact forces, it is primarily used to protect from cuts and burns.
Multi-layer tetrakevlar is used to provide protection from kinetic projectiles.
