AI Technical Summary

Technical Problem

Conventional vacuum insulation panels suffer from insufficient mechanical strength, impact resistance, and vulnerability to damage from mechanical, thermal, and chemical influences, as well as fire resistance issues, which compromise their structural integrity and vacuum integrity.

Method used

A vacuum insulation element is manufactured using a support body enclosed by a film covering made of fiber composite material, which includes reinforcing fibers embedded in a matrix, providing a protective exoskeleton that enhances mechanical and thermal stability, and can be applied at room temperature or under pressure, with optional thermal welding for sealing.

Benefits of technology

The fiber composite material enhances the vacuum insulation element's resistance to mechanical impacts, thermal stress, and chemical damage, maintaining structural integrity and vacuum integrity, especially in thin-walled applications.

Abstract

Method for manufacturing a vacuum insulation element (1) for use as a pressure- and impact-resistant, self-supporting element, wherein the vacuum insulation element (1) comprises a support body (2) and a film sleeve (3) enclosing the support body (2), and wherein the film sleeve (3) is completely enclosed by a fiber composite material (4), and wherein the vacuum insulation element (1) is a vacuum insulation panel, and wherein the film sleeve (3) comprises a sealing seam (31), and wherein the sealing seam (31) is folded to abut the support body (2), and wherein the vacuum insulation panel includes a recess (11), and wherein the method comprises the following steps: - Providing the support body (2) (Step A); and - Enveloping the support body (2) with the film sleeve (3) and the fiber composite material (4) (step B); wherein the step of enveloping the support body (2) comprises enveloping it with the film sleeve (3) and applying the fiber composite material (4) to the film sleeve (3), and wherein the step of enveloping the support body (2) with the film sleeve (3) and the fiber composite material (4) comprises completely enveloping the support body (2) with the recess (11), and wherein the application of the fiber composite material (4) is carried out by hand lamination or injection molding or winding or prepreg technology or resin transfer molding.
