Abstract

In order to improve and facilitate shimming between two parts, a deformable shim is provided that comprises a main structure of an at least partly cellular region. The main structure is compressible by plastic deformation from an initial volume to a deformed volume, wherein the deformed volume is smaller than the initial volume. In a deformed state, the main structure maintains the deformed volume without further or continuing compression force. Further, the main structure is arrangeable between a first aircraft component and a second aircraft component to create a predefined distance between the first and the second aircraft component.

First claim

The invention claimed is:

1. A deformable shim comprising:
a main structure of an at least partly cellular region;
a filler material infiltratable in the main structure to increase a stiffness of the shim; and
an outer interface layer on the main structure to create mechanical interlocking,
wherein the main structure is compressible by plastic deformation from an initial volume to a deformed volume, wherein the deformed volume is smaller than the initial volume;
wherein in a deformed state, the main structure maintains the deformed volume without a continuing compression force; and
wherein the main structure is arrangeable between a first aircraft component and a second aircraft component to create a predefined distance between the first and the second aircraft component,
wherein the outer interface layer comprises prepregs to create co-bonding between one of the components and the shim.

2. A mounting arrangement for mounting two components, comprising:
a first component;
a second component; and
a deformable shim according to claim 1 ;
wherein the deformable shim is provided between the first and the second component; and
wherein due to the deformable shim, a predefined space between the first part and the second part is generated.
