Abstract
Coating composite material sabot parts for reducing depleted uranium corrosion and sealing the surface of a machined composite sabot commences with cleaning the composite material sabot parts. Rinsing the composite material sabot parts, drying the machined composite sabot, and wiping the composite material sabot parts with a solvent follows cleaning. A moisture resistant insulator film is applied on the composite material sabot parts. Excess material is abrasively removed and additional coats are applied. The parts are wiped with a solvent between coats.
Claims10
A method for coating composite material sabot parts for reducing depleted uranium corrosion and sealing the surface of the composite material sabot parts, the method comprising the steps of:
- a) cleaning the composite material sabot parts;
- b) rinsing the composite material sabot parts;
- c) drying the composite material sabot parts;
- d) wiping the composite material sabot parts with a solvent;
- e) applying a moisture resistant insulator film on the composite material sabot parts, wherein the moisture resistant insulator film comprises a two-part epoxy material, wherein a first part consists essentially of from 18-21% by weight of Toluene, from 12-15% by weight of Methyl Isobutyl Ketone, and from 60-70% of epoxy resin, and wherein a second part consists essentially of from 40-43% Xylene by weight, from 3-5% of Ethyl Benzene by weight, from 8-11% of Butyl Alcohol by weight, from 3-5% Isopropanol by weight and from 40-44% Aliphatic Polyamonoamide by weight;
- and
- f) curing the moisture resistant insulator film.
A method for fabricating a composite sabot including a depleted uranium penetrator, the method comprising the steps of:
- a) fabricating a plurality of sabot molded parts from a composite material;
- b) cleaning the plurality of sabot molded parts;
- c) rinsing the plurality of sabot molded parts;
- d) drying the plurality of sabot molded parts;
- e) wiping the plurality of sabot molded parts with a solvent;
- g) applying a moisture resistant insulator film on the plurality of sabot molded parts, wherein the moisture resistant insulator film comprises a two-part epoxy material, wherein a first part consists essentially of from 18-21% by weight of Toluene, from 12-15% by weight of Methyl Isobutyl Ketone, and from 60-70% of epoxy resin, and wherein a second part consists essentially of from 40-43% Xylene by weight, from 3-5% of Ethyl Benzene by weight, from 8-11% of Butyl Alcohol by weight, from 3-5% Isopropanol by weight and from 40-44% Aliphatic Polyamonoamide by weight;
- f) curing the moisture resistant insulator film;
- and
- g) assembling the plurality of sabot molded parts and the penetrator.
