A method and a moulding device for the manufacture of composite products in a closed mould process wherein the mould comprises an inner liner and an inner liner for said method and device

摘要

The invention concerns a method and a moulding device in which an inner liner (3) of a fluoroplastic foil is used in a vacuum infusion moulding or vacuum assisted pressure process for the manufacture of fibre reinforced composite products in Resin Transfer Moulding (RTM) process. By this method and this moulding device, a simple closed moulding technique is provided, which is cost efficient, as the backing foil is reusable.
