BARD PAPER: VERA5011
design by Eamon
This is a table of manufacturing materials, from TL 7 to 17.
The benchmark material is Ultrahigh Density Polymer - which in actual life
is Ultra-High Molecular Weight Polyethylene. From the fact that 25mm of
this material stops a 0.38 cal slug at 150mm I derived it's toughness of
0.4, and reverse-engineered the High Density Polymer value (Which is High
Density Polyethylene). The next two entrys on the table are derived from
UHMWPE too, and are dervived from the techniques of ion-implantation
(where accelerated ions are injected into the bulk of the material and
provide additional cohesive force), and filling where a material's
properties are enhanced through the inclusion of a matrix of another
material. The manufacture takes place in zero-g, where the crystalline
structure of the polymer can be grown to greater tolerances.
The ion-enhanced metal composite consits of thin layers of complementary
metals bonded by ion implantation. The TL10+ advances are a mix of the
aforementioned techniques and the standard FFS TL10+ materials technology.
