Abstract: The present invention relates to a process for the production of a structured grain on the surface of a thermoplastic having continuous-fiber reinforcement by a textile sheet, where a mixture of at least one fiber material and of at least one thermoplastic is heated and pressed in a mold to a temperature above the softening point of the thermoplastic, where a structured grain has been applied on the internal side of the mold. The at least one fiber material comprises continuous fibers and takes the form of a regularly arranged textile sheet. The textile sheet and the structured grain on the internal side of the mold are oriented in relation to one another in a manner such that during the pressing procedure the textile sheet and the structured grain on the internal side of the mold are mutually superposed. After the pressing procedure, the mixture of the at least one fiber material and the at least one thermoplastic in the mold is cooled to a temperature below the softening point of the thermoplastic, with formation of the structured grain on the surface of the thermoplastic. The present invention further relates to a thermoplastic which has continuous-fiber reinforcement by a textile sheet and has a structured grain on the surface, and is obtained by the process of the invention.

Abstract: Disclosed herein is a computer-implemented method for controlling and/or monitoring at least one injection molding process in at least one injection molding machine. The method includes:



a) providing a set of input parameters by at least one external processing unit;
b) simulating an injection molding process based on the set of input parameters and determining at least one predicted process parameter of the simulated injection molding process;
c) performing at least one injection molding process using the injection molding machine; and
d) determining at least one actual process parameter of the injection molding process and comparing the actual process parameter and the predicted process parameter and adapting the simulation model based on the comparison.

Abstract: Disclosed herein is a process for producing marbled moldings, where a first molding compound and at least one further molding compound are injected from an injection unit of a screw injection molding machine into an injection mold,



where the injection unit includes a barrel, a screw having a screw tip and a nozzle where the screw is rotatable and is disposed in the barrel so as to be movable between a forward position and a backward position, with a smaller distance between the screw tip and the nozzle in the forward position than in the backward position,
and where the first molding compound includes a first polymer compound and a first colorant, and the at least one further molding compound includes a further polymer compound and optionally at least one further colorant.




Further disclosed herein is an apparatus for production of marbled moldings, and a process for producing the apparatus.

Abstract: The invention relates to a laminate composed of a first layer made of a first material, and of a second layer made of a polymer reinforced with continuous-filament fibers, where the first layer and the second layer have been bonded over a substantial surface area to one another, where the continuous-filament fibers in the second layer have been oriented in at least three fiber directions, where the three fiber directions lie within a plane oriented parallel to the first layer, and the fiber content has been adjusted in such a way that the coefficient of thermal expansion of the second layer in essence corresponds to the coefficient of thermal expansion of the first layer.
