Methods for manufacturing a protective helmet for the military and other uses are disclosed. Embodiments of the method include winding ballistic-tolerant tape or fibers to create a preform, placing the preform into a first mold member having an interior that defines a helmet-shaped cavity, and pressing together the first mold member against a second mold member that includes a pressurized bladder member. The method may further include pressurizing the bladder until the first and second mold members are heated and adhesives have melted or cured. The first and second mold members are cooled and the preform is removed from the first and second mold members.

Method of producing light weight protective helmets for military and other uses

A filament wound wheel is shown having a high percentage of continuous fiber oriented in the optimum load bearing direction for maximum strength. Also shown is a manufacturing method for the wheel including the steps of polar winding a continuous filament on a split mandrel to form a filament winding, slitting the filament winding on the mandrel to form two preforms, placing the two preforms in a back-to-back configuration, pressing each preform upon its split mandrel under heat to cure and join the preforms and separating the split mandrels from the joined preforms.

Filament wound wheel and a method for manufacturing the same

An energy absorbing beam is shown which may be manufactured by wrapping several side-by-side strands of resin coated filaments about an increasing number of pins mounted upon a base. The base then becomes part of a mold to which heat and pressure is applied for forming the coated filaments into a beam having a variable cross section with variable thickness. Devices for fastening the beam may be molded into the beam by passing the coated filaments about the fasteners as the filaments are wrapped about the pins.
