US 11,745,399 B2 · System and method for producing multi-material hybrids with a foam structure

Abstract

This system and method provide for manufacturing a multi-material hybrid structure comprising a single- or multi-layer sheet or tube, which are made of metals, fabrics, polymer and their combinations, and at least one layer or body made of formed resin. The methods include a simultaneous forming-injection process that followed with an additional sequence to initiate the forming process along with curing and/or solidification and/or bonding processes. The additional sequence provides a pressure drop inside the cavity using tool movement and or additional deformation of one/or several layers of the sheet using any fluid pressure, suction and/or electromagnetic force. The injection process can be used for any kind of synthetic or bio-based resin with or without fiber reinforcement. It is also integrated with supercritical assisted technology.

Dependent claims

A method of forming an article of manufacture comprising the steps of:

providing a blank;
securing the blank in a fixed position;
reforming a shape of the blank by injecting a resin under pressure against a first side of the blank to reform the blank by pressure of the resin against the blank;
providing a resistance pressure at the blank to counter pressure against the first side of the blank and control shape reformation of the blank;
whereby the blank is formed into an article of manufacture comprising a foamed material;
and,
wherein the resistance pressure at the blank to control reformation of the blank is provided by applying a fluid pressure against a side of the blank that is opposite the side of the blank against which the resin is injected under pressure.
