Embodiment Construction

[0035] figure 1 Shown is a schematic view of a composite material 1 comprising three layers in the example shown. The first layer 2 is in the middle, at figure 1 In the embodiment shown in , this layer is covered above by a second layer 4 and below by a third layer 6 . exist figure 1 Shown in the left area of ​​is three layers 2, 4, 6 separated from each other. The different elasticity of the materials used is shown by different hatching. The first layer 2 is made of a first material 8 which may be a film layer made of thermoplastic polyurethane, for example. figure 1 The longitudinal extension of the composite material 1 shown in is here the first direction. This is indicated by the lines 10 running corrugated in this direction in the first material 8 which is elastic in this direction. The first material 8 is inelastic in a second direction running perpendicularly to the longitudinal direction, which corresponds to the direction of the lines 12 , as indicated by the st...

Abstract

The invention relates to a composite material (1) comprising a first layer (2) made of a first material (8), and the first layer has an upper side and a lower side opposite to the upper side. The composite material also has a second layer (4) made of a second knitted material (14) and arranged on the upper side of the first layer (2). The first material (8) has a greater elasticity along a first direction than along a second direction different from the first direction, where the two directions run parallel to the upper side of the first layer (2). The first layer (2) and the second layer (4) are connected with each other in a laminar manner, such that the composite material (1) has a greater elasticity along the first direction than along the second direction.

Description

technical field [0001] The invention relates to a composite material having a first layer made of a first material, the first layer having an upper side and a lower side opposite the upper side, the composite The material also has a second layer arranged on the upper side of the first layer. Furthermore, the invention also relates to a method for producing such composite materials. Background technique [0002] Today, composite materials are known from many technical fields and cannot be left out of consideration. These composite materials are suitable for the most diverse applications and in these applications conventionally used materials are often completely excluded. [0003] The composite material realized by the invention can also be used, for example, in the field of orthopedics, in particular for various orthoses, but by no means restricted to this field of application. Orthoses are used, for example, to support joints or body parts of patients that have become we...
