Abstract

The invention relates to a process for producing fiber composite moldings comprising(i) a thermally crosslinkable fiber composite layer as backing layer, and(ii) a thermoplastic fiber composite layer as overlayer,by mutually superposing the fiber composite layer (i) comprising a thermally crosslinkable binder in the unhardened state and the thermoplastic overlayer (ii), and, in a molding press, converting them to the desired form and thermally crosslinking the same, which comprises a higher temperature of the first contact area of the molding press, where this has contact with the backing layer, than of the second contact area of the molding press, where this is in contact with the overlayer.
