Elastic interlayer assembly

Abstract

The invention relates to an interlayer assembly (100) having a first cover layer (101), a second cover layer (102) and a core layer (103). Because the core layer (103) is arranged between the first cover layer (101) and the second cover layer (102), the first cover layer (101), the core layer (103) and the second cover layer (102) form an interlayer structure. The core layer (103) has a shear stiffness greater than 5 MPa. The core layer (103) is configured to be recoverable such that at least 95% of the original thickness of the core layer (103) is recoverable when the thickness of the core layer (103) is reduced by 20% of the original thickness due to the compressive force.

Description

technical field [0001] The invention relates to a sandwich component having elastic properties and a method for producing the sandwich component. Background technique [0002] Composite materials are used in many applications, such as automobile manufacturing, aviation, sporting goods or housing parts for equipment, in order to create lightweight components. Thus, for example vehicle casings, luggage compartments or cabins of rail trains or aircraft and casings of equipment, i.e. high impact forces due to the impact of luggage items, due to vandalism or falling on the ground can cause permanent damage to the product. For example, bottom elements inside aircraft must be able to pass a drop test for drink bottles or other items, where from a certain height, the falling weight must not cause damage. The bottom must be of a correspondingly robust construction design. In this case, it can be constructed as a sandwich type to meet the lightweight building performance. However, ...

Problems solved by technology

In the case of impact loads, this inelastic deformation can lead, for example, to heaving or other irreversible damage

Therefore, the product does not have sufficient robustness to withstand such shock loads
