SECURING ASSEMBLY FOR A ROTOR BLADE
An apparatus for securing first and second skins to a core in a composite rotor blade includes an elongated member configured to be installed through a passage in the core of the composite rotor blade. The elongated member has a first end configured to be attached to an outer surface of the first skin and a second end configured to be attached to an outer surface of the second skin. The apparatus also includes a first patch configured to adhere the first end to the outer surface of the first skin, and a second patch configured to adhere the second end to the outer surface of the second skin such the elongated member extends from the outer surfaces of the first and second skins through the passage in the core.
METHOD AND SYSTEM FOR PRODUCING A REINFORCING BAR, AND RESULTING REINFORCING BAR
A method for producing a reinforcing bar by pultrusion, the method comprising the steps of: a) providing a source of fibres; b) assembling the fibres into a bundle; c) impregnating the bundle with a thermosetting resin; d) eliminating excess resin from the bundle; e) compressing the bundle in a centripetal manner; f) exposing the bundle to a radiant energy source; g) spraying particles onto a surface of the bundle; and h) exposing the bundle to radiation in order to initiate, on the surface of same, the polymerisation of the resin. The present invention also concerns a system provided with corresponding devices in order to be able to implement the method. The present invention also concerns a reinforcing bar obtained with the described method and/or system.
Hybrid veil as interlayer in composite materials
A flexible, self-supporting hybrid veil that is permeable to liquid and gas. The hybrid veil includes: (a) intermingled, randomly arranged fibres in the form of a nonwoven structure; (b) particles dispersed throughout the nonwoven structure, wherein a majority of the particles are penetrating through the thickness of the nonwoven structure; and (c) a polymeric or resinous binder present throughout the veil. Such hybrid veil can be incorporated into composite laminates, prepregs, fabrics and fibrous preforms.

INTEGRAL CERAMIC MATRIX COMPOSITE FASTENER WITH NON-POLYMER RIGIDIZATION
A method of forming an integral fastener for a ceramic matrix composite component comprises the steps of forming a fiber preform with an opening, forming a fiber fastener, inserting the fiber fastener into the opening, and infiltrating a matrix material into the fiber preform and fiber fastener to form a ceramic matrix composite component with an integral fastener. A gas turbine engine is also disclosed.
Vane made of composite material comprising metallic reinforcements, and method for manufacturing such a vane
A method for manufacturing a blade made of composite material for a turbine engine, in particular of an aircraft, the steps of injecting a resin in order to impregnate a fibrous preform woven in three dimensions and polymerizing the resin so as to form the blade that includes an airfoil, one longitudinal end of which is connected to a platform. The platform includes pressure and suction portions connected to the airfoil by a fillet, wherein a separation is formed in the fibrous preform between the pressure and suction portions. The method further includes reinforcing a leading edge of the airfoil; and reinforcing the fillets by integration of a metal reinforcement on at least one part of the pressure and suction portions of the platform and in the separation.
BUILDING PANEL
A building panel has a deep drawn transparent film having an inner face and a structure having solar cells on the inner face of the deep-drawn film. The structure has an inner face turned away from the film and an outer face on or closely juxtaposed with the inner face of the film. A reinforcement layer constituted as a mass of foamed granular particles is spread over the inner face of the structure in direct contact with the inner face of the structure without the interposition of an adhesive and is heat cured to the film.
Method For Manufacturing A Grille For A Thrust Reverser
The invention proposes a method for manufacturing a grille for a cascade type thrust reverser, of a jet engine, said method including the following steps: a) manufacturing a first component comprising long fibres, pre-impregnated by a thermoplastic or thermosetting resin; b) manufacturing, together with step a), a series of second components each including discontinuous fibres, pre-impregnated by a thermoplastic or thermosetting resin, step b) being carried out such that the second components are, on the one hand, arranged to transversally with respect to a longitudinal direction of the first component on at least one side of the first component and, on the other hand, spaced from one another according to this longitudinal direction, so as to form a comb-shaped structure, wherein the second components are consolidated to the first component.
