An in-situ melt processing method for forming a fiber thermoplastic resin composite overwrapped workpiece, such as a composite overwrapped pressure vessel. Carbon fiber, or other types of fiber, are combined with a thermoplastic resin system. The selected fiber tow and the resin are prepared for impregnation of the two by the resin. The resin is melted and the carbon fiber is impregnated with the melted resin under pressure at the filament winding machine delivery head, under pressure and the molten composite is maintained and is applied to the heated surface of a workpiece. The surface of the workpiece is heated to the melting point of the thermoplastic resin so that the molten composite more efficiently adheres to the heated surface of the workpiece and so that the layers of composite remain molten resulting in better adherence of the layers to one another.

Provided are a composite member, a seat for automobile, and a component for automobile that suppress a decrease in strength at a connection place between a metal member and a fiber-reinforced member. A composite member includes: a fiber-reinforced member formed by impregnating a plurality of sheet-shaped core materials with a matrix resin; and a metal member joined to the fiber-reinforced member. The composite member has a structure in which a part of the metal member is sandwiched and fixed between a plurality of the core materials stacked in a thickness direction at a joint place between the fiber-reinforced member and the metal member

A complex-shaped, three-dimensional fiber reinforced composite structure may be formed by using counteracting pressures applied to a structural lay-up of wetted fibers with mechanical features embedded or encapsulated therein. The mechanical features may be located on or at least partially between two or more pressurizable members, which may be internally pressurized within a mold. The mechanical features may operate as bearing plates, attachment fittings, or other structural elements. Assemblies of pressurizable members, fiber plies and mechanical features may be arranged to create complex composite structures with predefined load paths, enhanced structural capability or both.

A method of partially insulating an interior space of a pre-formed fluted core panel is disclosed herein. The fluted core panel includes a first facesheet, a second facesheet spaced apart from the first facesheet, and webs between the first facesheet and second facesheet. The interior space is defined between the first facesheet, the second facesheet, and adjacent webs. The method includes positioning a spacer in a first portion of the interior space, positioning a membrane between the spacer and a second portion of the interior space, and positioning insulation in the second portion of the interior space. Additionally, the method includes pressing the membrane against the spacer, curing the membrane, and removing the spacer from the first portion of the interior space.

A fiber-reinforced vehicle body structure includes a first frame made of fiber-reinforced plastic or carbon fiber-reinforced plastic and having multiple sections, and a second frame that continuously extends from any one of the multiple sections of the first frame.

An aerostructure is provided. The aerostructure may comprise an airfoil extending from a leading edge to a trailing edge, the airfoil comprising a stiffness and a camber, and a shape memory alloy (SMA) mechanically coupled to the airfoil via a resin, the SMA configured to be coupled to a current source, wherein at least one of the stiffness or the camber changes in response to a phase change of the SMA.

A reinforcing structure for a wind turbine blade is in the form of an elongate stack of layers of pultruded fibrous composite strips supported within a U-shaped channel. The length of each layer is slightly different to create a taper at the ends of the stack; the centre of the stack has five layers, and each end has a single layer. The ends of each layer are chamfered, and the stack is coated with a thin flexible pultruded fibrous composite strip extending the full length of the stack. The reinforcing structure extends along a curved path within the outer shell of the blade. The regions of the outer shell of the blade on either side of the reinforcing structure are filled with structural foam, and the reinforcing structure and the foam are both sandwiched between an inner skin and an outer skin.

Provided is a method of manufacturing an adaptable pre-cast resin-infused carbon-fiber beam, which method includes the steps of arranging a plurality of elongate carbon-fiber blocks side by side; arranging sheets to enclose the blocks and to extend over opposing faces of adjacent blocks; arranging the sheets to converge as an outwardly projecting elongate bead at a junction between adjacent blocks; and pulling on the elongate bead to inhibit resin flow between blocks during a resin infusion step. Also provided is a pre-cast adaptable carbon-fiber beam manufactured using that method; a method of manufacturing a wind turbine rotor blade; and a wind turbine rotor blade.

A pultrudate (1) with fibres running in the longitudinal direction (L) and a resin matrix which surrounds the fibres, and a top and a bottom side (2, 4), wherein the top side (2) has continuous elevations (5) and/or grooves (3) and the bottom side (4) has continuous grooves (3) or elevations (5), which are arranged such that elevations (5) and grooves (3) of one pultrudate (1) interact with grooves (3) and elevations (5) of the adjacent pultrudate (1′).

The invention relates to a vehicle rim having a rim body made from a fiber composite material, the rim body having two rim flange areas and a rim bed area connecting the two rim flange areas, and at least one rim flange area being reinforced by at least one fiber bundle and this at least one fiber bundle being surrounded by a compression wrap. The invention also relates to a vehicle wheel with the vehicle rim and to a production method for the vehicle rim.
