BONDED COMPOSITE STRUCTURE
A product made by a method for bonding fibers that includes providing a first fiber layer and a second fiber layer positioned below the first fiber layer to bond the first fiber layer with the second fiber layer. The method may also include providing a first additive layer. The first additive layer is located between the first fiber layer and the second fiber layer. Then, the method may further include activating the first additive layer by directing energy at the first additive layer.
Resistance spot welding method
A resistance spot welding method can be used to join polymeric and metallic workpieces together and includes the following steps: (a) placing an electrically conductive coating between a polymeric workpiece and a metallic workpiece, wherein the metallic workpiece has a textured surface facing the polymeric workpiece; (b) piercing the polymeric workpiece with first and second electrically conductive pins of a welding electrode assembly; (c) applying electrical energy to the first and second electrically conductive pins so that an electrical current flows through the first electrically conductive pin, the electrically conductive coating, and the second electrically conductive pin in order to at least partially melt the polymeric workpiece and the electrically conductive coating, thereby forming a weld pool; and (d) cooling the weld pool to form a solid weld nugget in order to establish a mechanical interface lock between the solid weld nugget and the textured surface.
Composite glass
A flame-retardant composite glass including a plurality of glass panes and a flame-retardant intermediate layer that is arranged between two first glass panes and includes a flame-retardant material that foams or swells up in the event of a fire, as well as an attack-resistant layer having a transparent plastic that is solid at room temperature. The flame-retardant composite glass has, between the first glass panes, an edge compound extending along and around the edges such that a chamber filled with said flame-retardant material is defined by the first glass panes and the edge compound. Between at least one of the first glass panes and the flame-retardant material, a primer layer is arranged that includes a material whose adhesion to the flame-retardant intermediate layer and/or to the glass pane becomes weaker in flame-retardant test conditions than it is in room temperature conditions.
Hot Melt Apparatus and Method of Use
In various embodiments, a hot melt device comprising a heating device that is automatically or manually triggered is configured so as to have its melt surface applied bringing a thermoplastic material in its solid form into contact with a surface via mechanical extrusion; using a heater to heat the thermoplastic material to a temperature above a melting temperature of the thermoplastic material while maintaining the contact of the thermoplastic material with the surface; allowing the heated thermoplastic material to cool to a temperature that is below the thermoplastic material's melting temperature; and allowing the heated thermoplastic material to bond the hot melt apparatus to the contacted surface without a solvent or use of a curing chemical reaction when the heated thermoplastic material is cooled to below the thermoplastic material's melting temperature while remaining connected to the structural body.
Membrane stacks
A process for preparing a membrane stack comprising the steps of: (i) interposing a curable adhesive between alternate anion exchange membranes and cation exchange; and (ii) curing the adhesive; CHARACTERIZED IN THAT said adhesive, when cured, has a Shore A hardness of less than 70 and an elongation at break of at least 50%.
Composite Panel Sandwich Structures with Integrated Joints
A method and apparatus for fabricating a composite structure. The method comprises defining a shape for the composite structure with a first face sheet. The method places core sections on the shape defined by the first face sheet. The method places an adhesive in a group of joint cavities. The method places a second face sheet on the core sections placed on the first face sheet, wherein the first face sheet, the core sections, and the second face sheet, define a structural assembly in which the group of joint cavities are present. The method cures the structural assembly with the adhesive in the group of joint cavities to fabricate the composite structure in which the adhesive fills the group of joint cavities when the adhesive is cured.
