Method of manufacturing an impregnated metal insert for a wind turbine blade root, the insert comprising an outer surface and an open end adapted to receive a fastening element for attachment to a wind turbine rotor hub, wherein the method comprises covering the insert outer surface with one or more resin pre impregnated fiber layers, and heating for curing such that a resin impregnated fiber layer adheres to the outer surface of the insert. The disclosure is further related to the method of manufacturing a portion of a wind turbine blade.

A process for manufacturing a ceramic matrix composite component, said process comprising inserting at least one fibrous sheet into a resin transfer molding system. The process includes wetting the at least one (dry or partially wetted) fibrous sheet with a neat first pre-ceramic polymer resin. The process includes injecting a second pre-ceramic polymer resin including a filler material into at least one fibrous sheet and curing the pre-ceramic polymer resin.

A preform for forming a composite structure, such as, but not limited to a panel for a building, house or the like includes a body substantially formed of a reinforcing material. The reinforcing material defines one or more compartments or sections. The compartments are fillable with a granular filler material through which settable liquid matrix material is impregnatable to form the composite structure. There is also disclosed a composite structure, a panel and related methods of forming the preform, the composite structure and the panel.

A metal plate, a fabric formed of reinforcing fibers, and thermosetting adhesives are layered on each other in a die in a die clamping direction. The thermosetting adhesives are forced to enter the fabric by clamping the die to produce a fiber reinforced plastic material with the thermosetting adhesives therein being in an uncured state. At the same time, the fiber reinforced plastic material is molded into a shape specified by the die. The thermosetting adhesives are allowed to cure in the die to cure the molded fiber reinforced plastic material, and the fiber reinforced plastic material and the metal plate are bonded each other.

Embodiments are described herein in the context of housings for electronic devices. In one embodiment, a housing can make use of an outer member, which can be formed of glass. The outer member can be secured with respect to other portions of the housing for the electronic device. The output member can also be protected at its edges by a protective side member. Still further, one or more antenna can be provided at least partially internal to the protective side member. The electronic devices can be portable and in some cases handheld.

Grid structure, such as a lattice or grid-stiffened structure and a process of manufacturing such a grid structure. Fiber material is laid up on a base tool to form intersecting ribs defining a grid with a plurality of cavities. In the same step fiber material is laid to form one or more; local substructures. Blocks are placed, at the positions of the cavities. The fiber material of the ribs and the local substructures is impregnated with a resin. Optionally, one or more layers of fiber material are placed on the base tool and/or over the ribs and the blocks to form an outer skin. The ribs, the local substructure and optionally the outer skin jointly consolidated to form, the grid, structure.
