The invention relates to a laid-yarn fabric serving as a reinforcement material in the manufacture of fibre composites, and comprising a connecting thread system and reinforcement threads (2) inserted into said thread system. The laid-yarn fabric forms a transversely elastic tube-like means (1) which is arranged to be passed over a core in order to form or to be comprised in said fibre composite. The invention likewise concerns a method of producing preforms for the manufacture of fibre composites, using such a transversely elastic, tube-like laid-yarn fabric. The laid-yarn fabric is applied on a core by the tube-like means (1) being passed over said core in such a manner that said tube-like means (1), on account of its transverse elasticity, drapes itself closely about said core. The laid-yarn fabric is then injected with thermosetting plastics, alternatively is heated, if the fabric is made from thermoplastic hybrid yarns.
