A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (ii) at least one consolidated fibrous insert (14) having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier may be a mass of activatable material.

Provided is a system and method for securing a seal between a thermoplastic liner and a metal boss for a composite cylinder. A metal boss can be integrated with a thermoplastic liner during a molding process. A bushing can be inserted into the metal boss and coupled thereto via threading. The bushing can further include a relief space region having a sidewall that is deformed from a first position to a second position in order to decrease a distance of the metal boss to the sidewall of the bushing, wherein the decrease provides a seal between the metal boss and the thermoplastic liner.

A lightweight vehicle pan assembly and for attachment to a vehicle frame via welding includes at least one metal flange and a molded pan body. The at least one metal flange has a weld portion adapted for welded attachment to the vehicle frame and an interface portion extending from the weld portion. The molded pan body has a base wall and at least one side wall extending upward from the base wall. The interface portion of the at least one metal flange is embedded in the at least one side wall of the molded pan body. The interface portion includes at least two rows of apertures defined therein for increasing a bond strength between the at least one metal flange and the molded pan body.

A method for fabricating a composite object with a computer-controlled apparatus, and the apparatus therefor. The comprises a reservoir containing liquid, curable first material, means to selectively solidify the first material and means to selectively deposit a second material. The method involves the steps of selectively depositing portions of the second material, and selectively solidifying portions of the first material, such that the solidified portions of the first material and the deposited portions of the second material form the composite object.

A method of manufacturing a composite fan blade with an outer part and a core includes laying up a plurality of continuous plies to achieve a stack, placing the core on a central portion of the stack of continuous plies to achieve an unfolded preform; folding the contin-uous plies about the core, such that the central portion of the stack folds about the core and the first portion is superimposed to the second portion, to achieve a folded preform; apply-ing pressure to the folded preform to achieve a consolidated curved folded preform; curing the consolidated curved folded preform to achieve the composite fan blade.

The invention relates to a method for manufacturing a blade made of composite material extending in a main elongation direction, the composite material of said blade comprising a fiber reinforcement densified by a matrix, the method comprising the following steps: a step of weaving warp yarns and weft yarns to produce a fiber preform, the fiber preform comprising at least one warp yarn adapted to form in the matrix at least one first portion of a channel, said portion of length of the warp yarn being directed according to the main elongation direction of the blade and opening at the root of the blade, the first channel portion formed in the matrix by said portion of length of warp yarn constituting at least one first portion of the internal airflow channel; a step of forming the fiber preform so as to produce a blade preform and densifying said blade preform;
characterized in that the weaving step comprises placing at least one second portion of yarn adapted to form in the matrix a second portion of a channel, said second portion of yarn being transversally directed relative to said main elongation direction and opening at the trailing edge of the blade, the second channel portion formed in the matrix by said second portion of yarn constituting also at least one second portion of the internal airflow channel.

An information handling system chassis is built at least in part from ceramic elements. For example, a transparent aluminum oxide ceramic portion covers a touchscreen to provide a rigid outer surface for accepting end user inputs. As another example, a ceramic chassis element has a ceramic material formed around a metal material of similar substance with bonding of the ceramic to the underlying material enhanced with oxidation of the outer surface of the metal material.
