US 2026/0166804 A1 · Tool For Manufacturing A Thermoformed Fiber Composite Component

Abstract

A mould for producing a hot-formed fibre composite component, has a forming tub with a base, a peripheral edge and a tub opening facing away from the base and delimited by the edge, a forming mould, arranged in the forming tub, for applying a preform, and clamping frame supporting an elastic membrane and having a lower boundary surface for application on an upper boundary surface of the edge. The edge and the clamping frame are designed to establish a fluid-tight connection with each other, so that the forming tub with the applied clamping frame can be evacuated by suction of air through a suction connection. The membrane is designed to cling to a preform located in the forming tub and adjacent, free base regions during evacuation, so that the preform is pressed onto the forming mould. The mould is heat-resistant up to a curing temperature of at least 200° C.

Dependent claims

A tool for manufacturing a thermoformed fiber composite component, the tool comprising:

a forming trough with a bottom, a circumferential edge, and a trough opening facing away from the bottom and bounded by the circumferential edge;
a forming tool arranged in the forming trough for placing a preform thereon;
and
a stenter frame, supporting an elastic membrane, with a lower boundary surface for placing on an upper boundary surface of the circumferential edge;
wherein the circumferential edge and the stenter frame are configured to form a fluid-tight connection with each other, so that the forming trough with the stenter frame placed thereon is evacuable by air extraction through a suction connection arranged in the forming trough;
wherein the elastic membrane is configured to nestle, in the direction of the bottom of the forming trough, against the preform located in the forming trough and adjacent free bottom areas during evacuating the forming trough, so that the preform is pressed onto the forming tool;
and
wherein the tool is temperature-resistant up to a curing temperature of at least 200° C.
