Reinforcement member comprising a structural adhesive on a polyester carrier

A reinforcement member comprising:

• a foamable heat curable structural adhesive on an outer surface of a carrier member, the foamable heat curable structural adhesive foaming to not more than about 400% of its original unexpanded volume, wherein the carrier member has a cross-section that does not comprise a constant thickness over its entire extension;
• wherein at least 90 wt.-% of the carrier member is composed of a fiber-reinforced polyester material having a degree of crystallinity of at least 60% and the content of fibers is within the range of about 20-70 wt.-% relative to the total weight of the fiber-reinforced polyester material;
• and
• wherein the foamable heat curable structural adhesive forms a non-uniform coating along the carrier member having a thickness of from 0.1 mm to 3 mm so that an outer shape of the reinforcement member differs from an outer shape of the carrier member, whereby the foamable heat curable structural adhesive forms a seamless connection to the carrier member.
