Abstract

Composite article comprising at least two layers of component a) and at least one layer of component b). The layers and are alternately linked together. Component a) has a compressive modulus of at least 10 MPa in contrast to the component b), which has a compression stress value at a compression of 40% of not more than 20 kPa. Composite articles are semi-flexible materials due to alternating rigid and flexible segments within the articles. Articles optionally contain at least one additional layer of component b), which layer is also alternately linked together with the respective layers of component a). At least one layer crosses at least one layer with an angle α in the range of 0°<α<180°, wherein both layers and are made of component b). Also, a method for producing those composite articles and the use of those composite articles in composite applications.
