Abstract

A process for producing a component from a fiber-reinforced plastic with a thermoset matrix. The process includes the steps providing a first and second thermoset prepreg layer, producing a cutout in the first thermoset prepreg layer, providing a thermoplastic layer in the semifinished product between the first and the second thermoset prepreg layer in the region of the cutout, and manufacturing the component with a first and second thermoset layer and a thermoplastic layer in the region of the cutout, where the thermoplastic layer is locked between the two thermoset layers. The component may be used in a vehicle, where the component has been produced from a fiber-reinforced plastic with a thermoset matrix by the abovementioned process.
