Verfahren zur Herstellung eines mehrschichtigen Faserkunststoffverbundhalbzeugs

The multilayer fiber reinforced plastic composite semi-finished product comprises layers, where a core layer (3) is arranged from one another on filling bodies (6) that are connected between two edge layers (2), which are connected with the core layer. One of the edge layers is a smooth muscle cell (SMC)-layer from a fiber assembly (5) drying-impregnated with a first matrix material (4), which is a shrink-reduced matrix material and comprises a composition, which is convenient to provide a Class-A-surface. A second edge layer is the SMC-layer from the fiber assemblies.

A second edge layer is the SMC-layer from the fiber assemblies drying-impregnated with a second matrix material, where the second matrix material is same as the first matrix material or a matrix material differentiating the first matrix material. The filling bodies of the core layer are connected by a third matrix material, and are drying-impregnated or coated with the filling bodies, which have a volume fraction of the filling body of the core layer is 50%. The edge layer has a layer thickness of 0.25-0.5 mm, and a density of 2 g/cm 3>. The core layer has a layer thickness 1-5 mm, and a density of 0.5 g/cm 3>. The first, the second and the third matrix material are present in a powdery form, and powder particles are electrostatically provided, where the matrix material of the core layer is the same matrix material as well as one of the matrix materials forming the edge layers or the matrix material differentiating the edge layers, which are mixable and/or crosslinkable with the matrix materials of the edge layers. The multilayer fiber reinforced plastic composite semi-finished product further comprises a layer, which is arranged between the edge layers that are selected from a group of layers comprising a carrier web, the SMC-layer, a filling body layer and a functional layer, where the functional layer comprises a conductive layer, whose surface resistance is set in a range of 5-100 kome
