The purpose of the present invention is to obtain a fiber-reinforced composite material having excellent appearance or mechanical characteristics, whereby a three-dimensional shape is molded with high productivity while appearance defects such as fiber meandering or wrinkling are suppressed. In this method for manufacturing a fiber-reinforced composite material, when a stack in which a plurality of sheet-shaped prepregs (X) in which a plurality of continuously arranged reinforcing fibers are impregnated with a matrix resin composition are layered in different fiber directions is molded into a three-dimensional shape by a molding die (100) provided with a lower die (110) and an upper die (112), a stretchable sheet (10) or a resin film (Y) used in the stack (12) is utilized. In this method for manufacturing a fiber-reinforced composite material, the stack may be pre-molded to obtain a preform, and the preform may be furthermore compression-molded to obtain a fiber-reinforced composite material.

The invention relates to a sandwich composite component (1) for the interior of a passenger aircraft. One problem to be solved by the invention is that of proposing a cost-effectively produced sandwich composite component which is suitable for the interior of a passenger aircraft and fulfils current fire protection requirements. The layer structure of the sandwich composite component (1) according to the invention comprises: a core layer (10) made of polymer foam; a reinforcing layer (20) comprising fiber composite material; and in addition at least one functional layer (50); wherein said layers of the layer structure are integrally bonded to each other, in particular by an adhesive bond. The fiber composite material of the reinforcing layer (20) comprises a woven or laid fabric made of reinforcing fibers and a polymer matrix, which has a higher density than the polymer foam of the core layer (10). Furthermore, the at least one functional layer (50) comprises a metal foil, in particular an aluminium foil, which has a thinner layer thickness than the reinforcing layer (20).

A fiber-reinforced composite blank for a fiber-reinforced composite component, in particular for a fiber-reinforced composite component of a wind turbine, comprising a layered construction with a form core consisting of or comprising a form core material, and a fiber layer adjoining the form core, said fiber layer consisting of or comprising a fiber layer material, and a plurality of reinforcing rods introduced into the form core and consisting of or comprising a reinforcing material, wherein the reinforcing material has a higher stiffness than the form core material. In this arrangement, the plurality of reinforcing rods is introduced into the form core at an angle to a form core plane. Furthermore, at least one reinforcing rod of the plurality of reinforcing rods is introduced into the form core at an angle to a direction orthogonal to the form core plane.

The invention relates to a method for producing a pressure accumulator (1), in particular for accumulating hydrogen in motor vehicles, wherein first of all an inner liner (3) of the pressure reservoir (1) is produced, preferably by means of a plastic blow molding process, wherein subsequently the inner liner (3) is provided, preferably braided, on the outside with a multi-ply reinforcing layer (9) including reinforcement fibers (8), and wherein the reinforcing layer (9) is then impregnated with a resin, preferably an epoxy resin, which, after curing, fixes the position of the reinforcement fibers (8) in the reinforcing layer (9). According to the invention the impregnation takes place from the contact region (K) of the outer surface of the inner liner (3) with the reinforcing layer (9) to the outer region of the reinforcing layer (9).

Method which is intended for producing an endless semi-finished product and having the following steps: feeding a silicone tube and a separate internal conductor, wherein the internal conductor runs in a first interior space formed by the silicone tube; encasing the fed silicone tube by production of an endless fibre tube, which encloses the silicone tube from the outside. The silicone tube is expanded so that a gap is formed between the silicone tube and the endless fibre tube. A matrix material is feed into the gap connecting the silicone tube and the endless fibre tube by virtue of the matrix material being cured.

The invention is directed to a composite product that includes a first layer made from a plastic and a support structure and a layer of fibers arranged between the first layer of plastic and the support structure. The first layer of plastic penetrates the layer of fibers at least at certain locations such that the first layer of plastic is mechanically interconnected with the layer of fibers.
