The present subject matter relates to composite carbon fiber sheets and methods for preparing the composite carbon fiber sheets. The composite carbon fiber sheet comprises a first carbon fiber sheet of a first weave and a second carbon fiber sheet of a second weave. A cut area is created in a first carbon fiber sheet of a first weave. A cutout is created from a second carbon fiber sheet of a second weave. The cutout is combined with the first carbon fiber sheet in the cut area to obtain the composite carbon fiber sheet.

An aircraft wing tip device (107) includes a unitized, monolithic leading edge torque box that is formed of polymer matrix fiber- reinforced material. The leading edge torque box includes a skin (160) that defines a continuous, uninterrupted outer mold line surface extending aftwardly from a winglet leading edge by a distance of at least approximately 60 percent of a local chord length. The leading edge torque box (172) further includes at least one internal component (162) extending between opposing inner surfaces of the skin and being integrally formed therewith.

The invention relates to the production of a reinforcing bar. During the manufacture of the deformed composite reinforcing bar, tow bundles which have a mineral composition and are coated with a lubricating agent are wound off bobbins at equal tension. Once a dense bar has been formed, a bandage is applied in the form of a circumferential winding of tow impregnated with a binder, forming the raised profile of the reinforcing bar. The reinforcing bar contains 72-88% fibres and 28-12% binder. The circumferential winding device is situated directly downstream of the device for compacting and forming a bar.

Disclose are a reaction container and a vacuum heat treatment apparatus. A method of preparing a reaction container comprises preparing a graphite mixture by mixing first and second graphite powders having particle sizes different from each other, preparing a graphite molded body by pressing the graphite mixture, and processing the graphite molded body. The density of the graphite molded body is in a range of 1.8 g/㎤ to 2.1g/㎤. A method of preparing a reaction container comprises preparing a graphite molded body by pressing graphite powders, and processing the graphite molded body to prepare the reaction container. A carbon source is impregnated into the graphite molded body or the reaction container, and density of the reaction container is in a range of 1.8 g/㎤ to 2.1g/㎤.

摘要:
A thermal processing and consolidation system is provided that includes an upper chamber assembly lower chamber assembly, and layup and demolding station, transfer assembly, automatic or permanent coupling system, and controller. The upper chamber assembly couples to the lower chamber assembly to form an enclosed plenum, the enclosed plenum operable to maintain a pressurized environment about a tool. The layup and demolding station receives the tool and facilitates the layup, bagging and sealing of unprocessed components at the tool. A transfer assembly accurately positions the tool on the lower chamber assembly in alignment with the upper chamber assembly. An automatic or permanent coupling system provides services to the tool and the enclosed plenum. A controller directs services to be supplied to the enclosed plenum and tool in accordance with a set of process parameters. This set of process parameters allows an individual set of unprocessed components to be thermally processed and consolidated.
