Abstract
Method and system for making a low cost, light weight impact deflecting material, comprising directionally aligned single walled carbon nanotubes in an epoxy resin composition, that is near impervious to bullets fired at close range at all angles of incidence, that does not deteriorate upon abrasion or when exposed to wide ranges of temperature and humidity, and that when used to construct a protective shield for a body armor vest protects the wearer from blunt trauma effects.
Claims6
An impact deflecting composition of matter, which is comprised of the following ingredients:
- SWCNTs (single walled carbon nanotubes), calcium carbonate, iron powder, epoxy resin, amorphous silica, non-fibrous talc, aromatic hydrocarbons, barium sulfate, alkyl phenol, mercaptan terminated polymer, and [2,4,6 dimethylamino methyl]phenol 1.
An impact deflecting composition of matter, which comprises by percentage weight the following ingredients:
- 1% SWCNT Mixture, 32% calcium carbonate, 5% iron powder, 15% epoxy resin, 1% amorphous silica, 8% non-fibrous talc, 0.5% aromatic hydrocarbons, 17.5% barium sulfate, 2.5% alkyl phenol, 15% mercaptan terminated polymer, and 2.5% [2,4,6 dimethylamino methyl] phenol 1 .
An impact deflecting composition of matter having 100% of its weight formed by mixing following ingredients within indicated ranges of percentage weight:
- 1.0% SWCNTs (single walled carbon nanotubes), 27.5 to 35.0% calcium carbonate, 5.0 to 10.0% iron powder, 10.0 to 15.0% epoxy resin, 1.0 to 5.0% amorphous silica, 7.5 to 12.5% non-fibrous talc, 0.5 to 2.5% aromatic hydrocarbons, 17.5 to 22.5% barium sulfate, 0.50 to 2.50% alkyl phenol, 10.0 to 15.0% mercaptan terminated polymer, and 0.50 to 2.50% [2,4,6 dimethylamino methyl]phenol 1.
A nanotube composite material highly resistive to penetration and delamination, and having impact deflection properties for avoiding blunt trauma effects, and made by the following method:
- preparing a controlled environment having a temperature in a range between 65 and 72° F., a relative humidity in a range between 30 and 50%, and an effective near DC electrical field strength;
- sprinkling SWCNTs uniformly onto a fiber glass cloth;
- uniformly covering said SWCNTs with a composition comprising calcium carbonate, iron powder, epoxy resin, amorphous silica, non-fibrous talc, aromatic hydrocarbons, barium sulfate, alkyl phenol, mercaptan terminated polymer, and [2,4,6 dimethylamino methyl]phenol 1;
- blending said SWCNTs and said composition to achieve uniform color and depth;
- and
- curing a blending of said SWCNTs and said composition in said controlled environment,
- where the effective near DC electric field strength is sufficient to directionally align the SWCNTs to form ropes of nanotubes parallel to a surface of said composition.
