摘要:
A method of manufacturing an acoustic treatment panel including at least one cellular structure with at least one anchor layer at the level of at least one of its faces. The anchor layer includes at least one adhesive sheet chosen from an adhesive film or a ply of pre-impregnated adhesive fibers in contact with the cellular structure. The method of manufacture includes, before the integration of the cellular structure in an acoustic treatment panel, a step of placing the anchor layer on a support, the adhesive sheet being the last to be placed, a step of placing the cellular structure on the anchor layer in contact against the adhesive sheet, and then a step of polymerization of the anchor layer and of the cellular structure.

A circuit breaker comprises a body made of a nanocomposite material formed by insertion of nano particles of a nano particles material in thermoplastic polymer of a thermoplastic polymer material. A method of reinforcing a material with another material, the method comprises mixing homogenously a thermoplastic polymer material with a nano particles material in a hot process to reinforce the thermoplastic polymer material with the nano particles material and forming a nanocomposite material by insertion of nano particles of the nano particles material in thermoplastic polymer of the thermoplastic polymer material. The nano particles material has a mechanical wear property, a dielectric property and a thermal property of fire retardant.

The present invention regards an article (5) comprising at least one composite material, comprising matrix material (19) and at least one micro-sized reinforcement element distributions (23), arranged in plies (13) positioned on top of each other. The nano-sized reinforcement elements (17, 17′, 17″, 17′″) are arranged in between and/or inside the micro-sized reinforcement element distributions (23), the nano-sized reinforcement elements (17, 17′, 17″, 17′″) having matrix material accumulation properties so as to provide a tailored increased reinforcement volume of said one or more distributions (23). The present invention regards a method for manufacture of a composite article (5) and use of the article (5).

A method is provided for producing a locally-reinforced profile component. The method includes the following steps: providing a primary profile to be reinforced which is made of fiber-reinforced plastic; providing a secondary profile made of plastic for local reinforcement of the primary profile; arranging the secondary profile on an outer surface of the primary profile to create the profile component; heating the profile component (IO); integrally-bonded connecting of the primary profile and the secondary profile by applying pressure to an outer surface and simultaneous use of a counter pressure to apply pressure to an inner surface of the profile component.

A method for manufacturing a lining element is provided. The method comprises laying a textile membrane onto a positive molding tool, applying first fibers and a matrix material onto at least one first region of the textile membrane for creating a semi-finished product of a framework supported textile, providing at least one sealing element along outer edges of the molding tool, covering the textile membrane and the at least one sealing element in an air tight manner by a covering means, evacuating the space between the molding tool and the covering means and curing the matrix material by heating the semi-finished product. Thereby, a lining element with a low weight and at the same time a sufficient directional stability is provided that furthermore allows to easily recycle the components of the lining element.

Portable apparatus for curing a part includes a wheeled frame having sliding part supports that move the part from a loading position to a curing position. A part clamping assembly is slidably mounted on the frame to apply clamping pressure to the part when the part is in the curing position in order to compact the part during a cure cycle. The clamping assembly includes a set of electrically heated shoes that heat the part to a cure temperature. A fan is provided to accelerate cool down the part after curing is complete. The heating and cooling operations are automatically performed by a programmed controller.

The device, for reinforcing the area of a part that serves to transmit force, includes two elements for clamping the part. The part can be made of a composite material with reinforcement fibers embedded in a resin. The force transmitted is in the drape-forming plane of the reinforcement fibers of the part. The two elements are at a portion of the part, and at least one linking body connects the two elements with pre-stress so as to generate compression at the portion. At least one linking body is secured to another part with a view to transmitting force.
