A process for the production of a component (1) made of a fiber composite material, and also a component (1) produced in this way, are stated, where a foil composite (7) with a thermoplastic outer foil (6) and with a thermoplastic inner foil (5) is produced, where the modulus of elasticity (E) of the inner foil (5) within a temperature range is smaller than the modulus of elasticity (E) of the outer foil (6), the inner foil (5) of the foil composite (7) is bonded to a molding (4) comprising a fiber material (2) and comprising a thermoset (3), the molding (4) is hardened, and the foil composite (7) is subjected to a heat treatment in the temperature range within which the modulus of elasticity (E) of the inner foil (5) is smaller than the modulus of elasticity (E) of the outer foil (6), where the outer foil (6) undergoes stress relaxation.
A process for the production of a component (1) made of a fiber composite material, where
A component (1) made of a fiber composite material comprising a fiber material (2) bonded in a matrix made of a thermoset (3), and also comprising a surface layer made of a foil composite (2) with a thermoplastic outer foil (6) and with a thermoplastic inner foil (5), where the modulus of elasticity (E) of the inner foil (5) within a temperature range is smaller than the modulus of elasticity (E) of the outer foil (6), where the inner foil (5) has been bonded directly to the thermoset (3) and/or to the fiber material (2), and where the outer foil (6) has undergone stress relaxation.
