摘要： A three-dimensional lattice includes a stabilizing grid having grid warp strands and grid weft strands crossing the grid warp strands. Grid cells are defined by adjacent grid warp strands and adjacent grid weft strands intersecting the adjacent grid warp strands. A projecting net has net warp strands and net weft strands crossing the net warp strands. Each subnet in a plurality of subnets uniquely corresponds to a corresponding grid cell. Each subnet includes a net warp strand portion intersecting both of the grid weft strands that define the corresponding grid cell. Each subnet includes a net weft strand portion intersecting both of the grid warp strands that define the corresponding grid cell. The net warp strand portion and the net weft strand portion of each subnet are spaced from a minimum surface defined by the corresponding grid cell.

摘要： Compression molding methods for improving the durability and weatherability of a composite material are provided. The methods include disposing a protective surface film on a composite material; adhering the protective surface film to the composite material; and compression molding the protective surface film. The composite material comprises a thermoplastic polymer and a reinforcement material. The protective surface film comprises at least one stabilizer that minimizes or prevents degradation of the underlying composite material when exposed to ultraviolet radiation and/or heat. The composite material may be heated in an oven having an environment comprising oxygen. The protective surface film may be disposed on the composite material prior to the composite material entering the oven; while the composite material is in the oven; or after the composite material exits the oven.

摘要： Sheet metal workpieces are preheated to a temperature in the range of about 100° C. to about 500° C. for warm forming between press-actuated forming dies. The forming dies are not heated, but are coated with a liquid lubricating material suitable for the forming of the preheated sheet metal workpiece. For example, the liquid lubricating material is suitably a halogenated hydrocarbon that will adhere to unheated die surfaces and serve in the forming of the sheet metal workpiece into a vehicle body panel or other product. But the liquid lubricating material is composed so as to evaporate from surfaces of the formed workpiece at a temperature below about 200° C., so that the workpiece does not have to be cleaned before it is decoratively finished. The lubricant material may be vaporized, for example, into a warm stream of air or nitrogen and carried to a recovery or disposal system.

摘要： A composite panel for a vehicle includes a plurality of layers bonded together by resin. A sensing assembly is arranged between at least two of the plurality of layers. The sensing assembly includes at least one of a piezoelectric layer to sense vibration of the composite panel when installed on the vehicle and a thermopile configured to sense changes in temperature of the composite panel when installed on the vehicle. The sensing assembly further includes a transmitter configured to transmit data to the vehicle based on an output of the at least one of the piezoelectric layer and the thermopile.

摘要： Presented are manufacturing control systems for fabricating composite-material structures, methods for making/operating such systems, and resin transfer molding techniques for ameliorating race-tracking effects in fiber-reinforced polymer panels. A method for forming a composite-material construction includes confirming, via a system electronic control unit (ECU), that a fiber-based preform is placed in a mold cavity and that opposing mold segments of the molding apparatus are sealed together. A filler, such as a compressible bladder, a cluster of spring-biased pins, or a spray-chopped fiber bed, is introduced into a void between the fiber-based preform and a tool face of one mold segment to thereby eliminate an unwanted resin race track. The system ECU commands a resin pump to inject resin through a primary gate of the molding apparatus and into the mold cavity to thereby impregnate the fiber-based preform with the resin. One or more vents operate to evacuate air from the mold.

摘要： A method of mitigating galvanic corrosion on a vehicle is provided for use of metals with carbon containing composites. An electrically conductive material comprising a plurality of electrically conductive metallic particles and a polymer is applied to a corrosion susceptible region of an assembly having a carbon-reinforced composite and a metal. The electrically conductive material has an electrical conductivity of greater than or equal to about 1×10−4 S/m and serves as a sacrificial anode to mitigate or prevent corrosion of the metal in the assembly. Also provided are assemblies for a vehicle having reduced galvanic corrosion that include a metal component in contact with a carbon-reinforced composite, which defines a corrosion susceptible region having an electrically conductive material disposed therein.
