An example method for forming a flat composite charge into a composite blade stiffener includes cutting a flat composite charge along a cut line into a first piece and a second piece having an angle, positioning the first piece and the second piece of the flat composite charge on a forming mandrel about a tooling plunger, activating the tooling plunger to drive the first piece and the second piece into a cavity of the forming mandrel resulting in the first piece and the second piece folding at the cut line, withdrawing the tooling plunger from the cavity of the forming mandrel, compressing the forming mandrel to apply a lateral pressure to the first piece and the second piece folded into the cavity, and applying a vertical pressure to a first flange and a second flange of the first piece and the second piece, respectively, to form the composite blade stiffener.

A system for continuous process manufacturing of composite friction units uses one or more array gates with a plurality of cutouts each sized to receive one of a plurality of reinforcing fiber fabric therethrough. The system also uses a resin plenum with plenum chamber and a plurality of dispensing tube assemblies. Each of the plurality of dispensing tube assemblies corresponds to a different cutout and includes dispensing bores positioned to dispense resin onto one of the reinforcing fiber fabrics. The system also uses a forming die that receives the reinforcing fiber fabrics with the resin to form a composite panel as they pass through the forming die.

The present invention relates to a heating element composition capable of three-dimensional molding and a film heater formed therefrom. Specifically, the present invention relates to a heating element composition capable of three-dimensional molding and a film heater formed therefrom, wherein the heating element composition has high extensibility and excellent high temperature durability which is in a conflicting relationship with extensibility, so that mechanical damage such as cracks during stretching can be suppressed, has the characteristic of being stably maintained in a molded shape rather than being restored to an original shape after molding, like conventional stretchable materials, can minimize the change rate of resistance when deformed by three-dimensional molding, can be cured at 150 C. or less, and can form a heating element by various printings or coatings so as to be applied to various film heaters.

The present invention relates to vacuum forming process for moulding a thermoset material and a start-up process for moulding a thermoset material. The present invention also relates to articles produced by the vacuum forming process.

A structural panel comprises phenolic skins formed over a honeycomb core. The skins are bonded to the honeycomb under vacuum and heat, providing a panel capable of forming to desired shapes. The panel is 30% lighter than aluminum honeycomb panels of similar thickness, equivalent in strength to aluminum honeycomb panels, and meets the very stringent fire, smoke and toxicity norms of the industry. Additionally the product also reduces the thermal load, has very high heat resistance and is corrosion resistant. The use of this product is not limited to flat profiles, but can also be used to mold double curved or other three dimensional profiles.
