The present invention relates to a molding made of reactive foam, wherein at least one fiber (F) is arranged partially inside the molding, i.e. is surrounded by the reactive foam. The two ends of the respective fiber (F) not surrounded by the reactive foam thus each project from one side of the corresponding molding. The reactive foam is produced by a mold foaming process. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings according to the invention from reactive foam/the panels according to the invention and also provides for the use thereof as a rotor blade in wind turbines for example.

The present invention relates to a molding made of foam, wherein at least one fiber (F) is located partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fiber (F) not surrounded by the foam thus each project from one side of the molding. The foam is produced by polymerization of a reactive mixture (rM) comprising at least one compound having isocyanate-reactive groups, at least one blowing agent and at least one polyisocyanate.

An embodiment rotorcraft main rotor system, including a yoke, a rotor blade, and a grip assembly attaching the rotor blade to the yoke. The grip assembly includes a grip body formed from a contiguous laminated composite and has a substantially constant thickness, where the grip body has an upper extension, a lower extension and a connecting portion connected between an inboard end of the upper extension and an inboard end of the lower extension. An inside surface of the upper extension faces, and is substantially parallel to, an inside surface of the lower extension, and the upper extension has first features and the lower extension has second features that are aligned with the first features, where the first features and second features each include at least one of an edge contour, attachment holes, or first protective elements.

A composite assembly has an outer spar component having an outer spar component inner profile, an inner spar component having an inner spar component outer profile substantially complementary to the outer spar component inner profile, and an adhesive disposed between the outer spar component and the inner spar component.

A composite manufacturing system has a tool having a substantially planar first portion and a substantially planar second portion, a first carriage configured to carry a first roller that is configured to selectively apply pressure to the first portion, a second carriage configured to carry a second roller that is configured to selectively apply pressure to the second portion, and the first carriage and the second carriage are movable relative to the tool.

A replacement vibration absorbing device for replacing a wear wrap on a flexbeam includes a sleeve having a plurality of layers of vibration absorbing material, wherein an edge of the sleeve is cut so that the sleeve may be installed around a generally central portion of a flexbeam.

An assembly of two parts, one of the parts being made of composite material with fiber reinforcement obtained from a fiber preform made by three-dimensional weaving and densified with a matrix, the assembly including a mechanical anchor element secured to one of the parts and inserted inside the other part.

An injection molding device for fabricating a part, the device including an injection mold, the mold being formed of a support and a countermold that are distinct and that define between them a mold cavity presenting a first shape; and at least one injection device for injecting a fluid material into the mold cavity; the device including deformation elements configured to modify the shape of the mold cavity into a second shape distinct from the first shape.

A system for manufacturing a particulate-binder composite article including a mold defining a mold cavity, a first opening into the mold cavity, and a second opening into the mold cavity, a mass of a particulate material received in the mold cavity, a binder source in selective fluid communication with the mold cavity by way of the first opening, the binder source including a binder material, a first filter disposed across the first opening, the first filter being permeable to the binder material and substantially impermeable to the particulate material, and a second filter disposed across the second opening, the second filter being permeable to air and substantially impermeable to the particulate material.

A fiber blank woven as a single piece by three-dimensional weaving to make a closed box-structure platform out of composite material for a turbine engine fan. In each plane of the fiber blank, a set of warp yarns interlinks layers of weft yarns in first, second, and third portions of the fiber blank, while leaving a closed non-interlinked zone separating the first and second portions over a fraction of the dimension of the fiber blank in the warp direction between an upstream non-interlinking limit and a downstream non-interlinking limit, and while leaving at least one open non-interlinked zone separating the second and third portions over a fraction of the dimension of the fiber blank in the warp direction from a non-interlinking limit to a downstream edge of the fiber blank. A method of fabricating a preform for the closed box-structure platform can use such a fiber blank.
