In a process of producing a composite fiber component, fiber-containing layers pre-impregnated with resin and dry fiber-containing layers are alternately deposited on one another. The pre-impregnated fiber-containing layers have an excess of resin. The fiber composite component is integrated by causing the excess resin of the pre-impregnated layers to infiltrate the adjacent dry fiber-containing layers.

Method for producing a fiber connection component

A multilayer, flexible planar material for delimiting a matrix supply chamber during the production of fiber-reinforced plastic components made of fiber composite semifinished products includes a multifunction laminate, which has a diaphragm, a textile layer, which is laminated on the diaphragm, and a spacer layer, which is disposed on the textile layer.

Multilayer, flexible planar material

Injection structure with a fiber-composite semifinished product for manufacturing a fiber-composite component, having a gate device for feeding matrix material, a distribution fabric, and a barrier layer that is impermeable to the matrix material, wherein the distribution fabric is arranged between the gate device and the fiber-composite semifinished product, and the barrier layer is arranged between the distribution fabric and the fiber-composite semifinished product, as well as device for manufacturing a fiber-composite component by this injection structure.

Method and devices for producing fiber-reinforced components

A method and a device are provided for bonding a dry fiber strip to a dry fiber strand in continuous, uninterrupted operation. A bonding agent, activatable by supplying heat, is provided on the fiber strip and the fiber strand, which has at least one flat mantle surface. The fiber strip and the fiber strand are unwound from respective supply rolls, and the flat mantle surface of the fiber strand is positioned on the fiber strip during the unwinding procedure. Heat is supplied during the unwinding procedure to cause activation of the binder and gluing of the fiber strip and the fiber strand.

Method for bonding a dry fiber strip to a dry fiber strand

Production device and method for producing fiber-reinforced plastic components comprising a semi-finished prepreg product and a dry semi-finished textile product with an aeration and deaeration chamber and an exhaust line opening into the same for producing a vacuum and a semi-finished textile product chamber to receive a dry semi-finished textile product. Into the semi-finished textile product chamber an injection line for inserting resin opens, whereby a prepreg chamber for receiving a semi-finished prepreg product is provided. The prepreg chamber is located against the aeration and deaeration chamber in an air-permeable manner and the semi-finished textile product chamber is located against it at least in areas in an air-impermeable and resin-permeable manner. Due to the air-permeable membranes, a vacuum in the aeration and deaeration chamber generates a vacuum both in the prepreg chamber and in the semi-finished textile product chamber. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Method and device for producing fiber-reinforced plastic components

Degassing device for degassing matrix material in the manufacture of fiber-composite components with a support device, a distribution fabric, a gate device, a discharge device, a matrix-material-impermeable barrier layer, which is sealed with respect to the support device by a seal and thus forms a first chamber of the degassing device located around the gate device, as well as a degassing device for degassing matrix material in the manufacture of fiber-composite components with a first connection, for conducting the matrix material to be degassed into the degassing device, a second connection for conducting the degassed fluid out of the same, and a third connection for applying negative pressure to the interior of the same, an inner body, a resin-impermeable and air-permeable film, and an outer housing.

Degassing device for degassing matrix material in order to produce fiber-reinforced components

In a method for producing fiber-reinforced plastic components made of dry fiber composite preforms by an injection method for injecting matrix material, the arrangement of the fiber composite preform on one surface of the preform resulting in a flow promoting device, on a tool, creates a first space by a gas-permeable and matrix-material-impermeable membrane surrounding the preforms. Formation of a second space arranged between the first space and the surroundings by a foil, which is impermeable to gaseous material and matrix material, is provided, with removal by suction, of air from the second space resulting in matrix material being sucked from a reservoir into the evacuated first space and with the flow promoting device causing distribution of the matrix material above the surface of the preform facing the flow promoting device, thus causing the matrix material to penetrate the preform vertically.

Method and device for producing fiber-reinforced components using an injection method

A method for producing a fibre-reinforced plastic component includes (1) prefabricating an unwindable part of the plastic component as a prepreg semi-finished material; (2) prefabricating a non-unwindable part of the plastic component as a textile semi-finished material; (3) applying a resin film to said textile semi-finished material; (4) joining said textile semi-finished material and said prepreg semi-finished material in a curing device; (5) evacuating said curing device; and (6) subjecting said curing device to temperature and pressure treatment in an autoclave.
