Producing shaped plastic articles, useful as construction elements, comprises heating laminate between membrane and shaping with hot forming tool

摘要

A laminate assembly is placed between two membranes (8a, 8b) which are then heated and shaping of the laminate is then carried out using a hot forming tool. A method for producing a shaped plastic article preferably comprising a fiber-reinforced plastic material comprises the following steps: (A) stacking at least one plastic layer to form a laminate; (B) placing the laminate between two or more membranes; (C) heating the laminate to a first temperature by heating at least one membrane; and (D) shaping the laminate using a forming tool heated to a second temperature. Independent claims are also included for the following: (A) Process apparatus, comprising a device for holding the laminate between the membranes, a heating device for at least one membrane, a forming tool and a device for applying pressure to the membrane/laminate assembly; and (B) Membrane with heating elements for producing shaped articles from fiber-reinforced plastic using a suitable forming tool.
