A method for producing a fiber composite laminate, including the steps of applying pressure and/or heat to a first preform, which has one or more dry fiber layers and a thermoplastic elastomer, such that the thermoplastic portion of the thermoplastic elastomer completely impregnates the dry fiber layers of the first preform in at least one first region and only partially impregnates the dry fiber layers in at least one second region and, in a thermosetting polymer matrix, impregnating and curing the fiber layers of the second region of the first preform that are still dry and have not been impregnated with the thermoplastic portion of the thermoplastic elastomer.

The present invention relates to a composite article comprising at least two layers (A) of component a) and at least one layer (B1) of component b). The respective layers (A) and (B1) are alternately linked together. The component a) has a compressive modulus of at least 10 MPa and can, therefore, be considered as a comparably rigid component, which can be also assigned as rigid core element, in contrast thereto the component b) has a compression stress value at a compression of 40% of not more than 20 kPa. By consequence, component b) can be considered as a comparably flexible (elastic) component. Therefore, the composite articles according to the present invention can be considered as semi-flexible materials due to the combination of alternating rigid and flexible segments (layers) within those composite articles. The composite articles according to the present invention may further comprise at least one layer (B2) of component b), which layer is also alternately linked together with the respective layers (A). In addition, at least one layer (B2) crosses at least one layer (B1) with an angle α in the range of 0°<α<180°, wherein both layers (B1) and (B2) are made of component b). The present invention further relates to a method for producing those composite articles as well as to the use of those composite articles in composite applications, for example, wind rotor blades or boat hulls or insulation applications, for example for curved walls or roofs or between rafters.
