SYSTEM AND METHOD OF MANUFACTURING FIBER BASED ARTICLES WITH STEAM MOLDING

In an example method, a NWM molding blank, including a non-woven material held in compression by a binder, is placed in a separable mold, and heated to a melting temperature of the binder. The molding blank expands, forming as an intermediate NWM object a NWM molded object with a 3D geometric form. The intermediate NWM object is cooled through a temperature band with an upper boundary and a lower boundary, and further cooled to a solidifying temperature of the binder. The upper boundary is above the solidifying temperature and the upper boundary is lower than the binder melting temperature. While in the temperature band, the mold is separated, rendering accessible an exposed surface of the intermediate NWM object. The object is then transported to a contoured forming surface of a forming base, by an actuatable arm having an end effector gripping the exposed surface via vacuum suction, lifting the object from the mold and placing the object on the contoured forming surface. Optionally, the end effector contact surface includes a final forming feature. The actuatable arm compresses the intermediate NWM object against the contoured forming surface, and the optional end effector final forming feature and continues compressing until cooling to the solidifying temperature.

Methods and apparatus for curing composite nacelle structure
10137607 · 2018-11-27 · ·

Methods and apparatus for curing curved cylinder-like workpieces (e.g., in the shape of a half or full barrel) made of composite material, such as nacelle honeycomb core composite sandwich structures. These methods enable tailored curing of composite nacelle structures, to significantly reduce capital cost and fabrication cycle time. In lieu of an autoclave or oven, a pressurized ring-shaped cure volume is defined by a partitioned enclosure that mimics the cylinder-like shape of the composite nacelle structure with only limited clearance (e.g., a partitioned enclosure comprising inner and outer concentric cylinder-like walls). A tool (e.g., a mandrel) and at least one composite nacelle structure supported thereon are placed in the cure volume for curing. Integrally heated tooling, optionally in combination with other heating methods, such as infrared heaters, is utilized to provide the temperature profile necessary for cure.

Process for producing automotive glass with member

Provided is a process for producing an automotive glass with a member in a highly efficient and space-saving manner. The process for producing an automotive glass with a member comprises bonding together an adhesion surface of an adherend and an adhesion surface of an automotive glass using an adhesive, and then curing the adhesive using a superheated steam generator, thereby attaching the adherend to the automotive glass; wherein the superheated steam generator comprises (1) a boiler part for generating steam, (2) a superheating unit for superheating the steam generated in the boiler part, and (3) a superheated steam vessel equipped internally with one or more heaters and one or more superheated steam outlets for discharging the superheated steam supplied from the superheating unit; and wherein the step of curing the adhesive is performed by covering the adherend placed on the automotive glass with the superheated steam vessel, spraying the superheated steam from the one or more superheated steam outlets to the adherend, and then spraying dry gas.
