摘要： A composite storage tank may include a wall structure including at least three regions including an inner region, an outer region, and at least one permeation barrier. Another region may be optionally incorporated for venting potential permeation of fluids. The at least one permeation barrier and/or the venting layer may be strategically positioned between the inner region and the outer region to reduce or at least partially prevent fluid permeation of the inner region or the outer region. A vehicle may include such a composite storage tank. Methods of forming a composite fluid storage tank may include forming an inner composite region, applying a permeation barrier to an outer surface of the inner composite region, forming an outer composite region, and curing the inner composite region and the outer composite region with the permeation barrier to form the composite fluid storage tank.

摘要： A machine for manufacturing tube elements comprised of tape strips. The machine includes a shaft, a disk mounted to one end of the shaft, a motor coupled to an opposite end of the shaft, and a plate mounted to the shaft. The plate includes a plurality of spools mounted to the plate, where a separate one of the strips is wound on each spool. In one embodiment, the machine further includes a rail positioned adjacent to the disk, a slide slidably secured to the rail and including an end support configured to hold ends of the tape strips, and an indexer configured to pull the slide on the rail away from the disk. The tape strips are unwound from the spools when the indexer pulls the slide in a manner so that the tape strips ride in a spaced apart manner around the disk to form the tube element.

摘要： A continuous filament additive manufacturing machine for building a part by laying down a continuous mono-filament or composite filament material layer by layer on a tool or substrate. The machine includes a system, such as a robot, operable to move in three degrees of freedom, and a placement module coupled to the system and being configured to deposit the continuous filament material. The placement module includes a guide for guiding the material to the part and an ultrasonic compaction device for compacting the material as it is being deposited from the placement module. The compaction device includes an ultrasonic horn having at least one guide hole through which the material passes before it is laid down and compacted. The ultrasonic horn is ultrasonically vibrated to melt or flow the material and cause the material to fuse and be compacted to the tool or substrate.

摘要： Apparatus and methods of stretch-forming material are provided. In one example embodiment, a variable material stretch-forming apparatus comprises a stretch-forming assembly configured to stretch-form at least one section of a sheet of material to a longer length than at least one other section of the sheet of material before the sheet of material is applied to a tool.

摘要： Methods of forming a composite structure include conforming at least one ply of material to a forming surface of a tool having differing features. Apparatuses for forming a composite structure include a forming tool and a material feed assembly configured to hold a supply of material, where the material feed assembly may be configured to pivot the supply of material relative to the forming tool. Composite structures having an at least partially annular shape are formed by an at least partially automated process.
