Abstract: Novel woven materials, producible by a new weaving method, are described that comprise single or doubled warps and wefts in the form of tapes that are preferably partially stabilized type of fibrous tape. These fibres are caused to occur in a non-linear arrangement during the weaving process. The non-linear fibres can be subsequently straightened by pulling the tape longitudinally.
