Lightweight spherical blast resistant container

Abstract

This invention is a novel minimum weight and minimum volume blast resistant container. The container is made of a blast resistant, fiber reinforced, polymer resin matrix, composite material. The invention employs a novel construction configuration whereby the container is created by winding a collection of continuous reinforcing fiber filaments, called a tow, or winding a collection of tows called a tape, around a spherical tool or mandrel. Prior to winding, resin is applied to the tow or tape by immersion into a resin bath. Such an approach provides an optimized minimum weight and minimum volume solution by fully utilizing all the material in the part, whereby ultimate tensile strength can be simultaneously developed everywhere in the container.
