摘要:
A backpack frame is molded integrally from composite fiber and resin material to provide a light yet strong frame. The frame includes top and bottom members and a pair of side members. A pair of vertical ribs extend between the top and bottom members, and a plurality of horizontal members extend between the side members. The frame has torsional flexibility about a longitudinal axis which is generally parallel to the side members. Each of the ribs has a generally kidney-shaped cross section which is provided by a groove in the rib. A sack is slidably attached to the frame by elongated beaded attaching members which are sewn to the sack. Each bead is slidably inserted into a key-hole shaped channel in one of the side members. A suspension system includes shoulder straps, a waist belt, and a back pad. Each part of the suspension is formed from closed cell foam which is compression molded to form air-circulating grooves. One or both sides of the foam has a flame laminated skin.
摘要:
A composite clad structure and method of producing same that is resistant to both chemical corrosion and ignition, including a metal base with an attached reactive metal component, such as titanium or zirconium, that resists initial ignition and has improved ability to arrest burning of the reactive metal, once started. The composite structure comprises a structural base layer such as carbon, low alloy, or stainless steel, an intermediate layer of high thermal conductivity metal such as copper, aluminum, silver and their alloys clad to the structural base layer and a corrosion resistant layer of reactive metal selected from the group consisting of titanium, zirconium and their alloys that is clad to the intermediate layer.
