AI Technical Summary

Problems solved by technology

Also, they do not have a uniform density distribution due to the lamination method
As such, they often do not meet the geometric and acoustic requirements imposed on these special molded parts

Embodiment Construction

[0097] Thus, in figure 1 A three-dimensional thermoforming kit 1 for a PIV (vacuum insulation panel) is shown in .

[0098] This set contains:

[0099] - three-dimensional porous structure 5, and

[0100] - An outer cover 7 comprising (or consisting of) the wall 7a.

[0101] It should be understood that the expression "three-dimensional" (3D) is equivalent to not being (entirely) planar, as in the usual sense. Thus, like the fiber fabric structure 5, the thermoforming sleeve 1 is represented as curved; but it can also exhibit the usual local elevations and / or depressions, as for example in respectively Figure 7 in districts 25, 27 or Figure 5 , 6 Zones in (Zones 21, 23). These depressions and protrusions (or bumps) may be referred to as "embossing".

[0102] The porous structure 5 will advantageously be based on a powder or fibrous fabric structure and will thus contain polymer fibres, mineral fibres (eg glass, basalt) or natural fibers (eg cellulose, flax, hemp). Th...

Abstract

The invention relates to a three-dimensional vacuum thermal insulation element (1) comprising: a compressed three-dimensional porous structure (5); and a shell (7) closed in an airtight manner, comprising a thermoformable barrier wall (7a) and enclosing the porous structure which is arranged between two major surfaces of said barrier wall (7a), and in which, at ambient external temperature and pressure, there is a pressure of between less than 105Pa and more than 10-2Pa, characterized in that the barrier wall (7a) is thermoformed at the site of said two major surfaces, between which the porous structure (5) has a curved shape and / or reliefs and / or depressions.

Description

technical field [0001] The invention relates to a three-dimensional thermoformed element. Background technique [0002] Many lining elements, typically interior linings as in vehicles such as aircraft, trains, ships or automobiles, have been used for protective purposes, typically thermal and / or acoustic protection, or as fire protection elements. [0003] With typically molded elements of this type, problems remain, both in terms of structural realization and conditions of use. For example, there are elements with compounds in powder and / or porous form which cause dispersion and / or handling problems. Structural problems may also arise, for example in the context of a compromise to be made between protection requirements on the one hand (e.g. thermal and / or acoustic and / or fire protection as mentioned above) and volume and / or weight on the other hand under, especially when installed in narrow and / or inaccessible locations. Special shape requirements may also arise. [00...
