Method for Post-Curing a Profile of Fibre-Reinforced Plastic Material

A method for post-curing a profile of fibre-reinforced plastic material comprising the steps of:

• a. supplying the profile, which profile adopts a substantially linear configuration in the longitudinal direction thereof when in a natural, relaxed or stress-free state, in a non-linear configuration in the longitudinal direction thereof where, as a result of supplying the profile arranged out of its linear configuration in the longitudinal direction thereof, stresses are present in the profile not otherwise present when in the natural, relaxed or stress-free state, and wherein said profile comprises a number of fibres extending along one another, which are embedded in a partially cured thermosetting matrix material;
• and
• b. by means of a heat treatment device, carrying out a heat treatment on the profile while the profile is in the non-linear configuration in the longitudinal direction thereof, and during said heat treatment the matrix material is post-cured, wherein the glass-transition temperature of the matrix material is increased as a result of the heat treatment and wherein a temperature to which the profile is exposed during the heat treatment remains below the glass-transition temperature of the matrix during the heat treatment.
