And judging by the chemical hydrocarbon structure it's something which can be easily be programmed into DNA.
In fact UHMWPE fiber seems to be a just be an overgrown fat molecule.
If a soldier is induced to produce this fiber in a couple of layers of cells right beneath the skin, he could have built in armor that rivals anything a vehicle could carry, and light enough to move around in.
Refer to pic.
It doesn't have a high tensile strength, only compressive. That means if you drew out a long stick of it, it would be easily bent or broken. This means it couldn't serve as an anchor for muscles… Calcium crystals are better at that.

>Under tensile load, UHMWPE will deform continually as long as the stress is present—an effect called creep.
Something like rusar composite would be a structural member, because aramid fibers HMW plastics when it comes to tensile strength.
