Abstract

A tubular material based on a fabric reinforced resin, said material comprising layed up fabric layers, the inside and outside layers consisting of bidirectional braided sheaths, said latter two layers sandwiching an intermediate, unidirectional braid consisting primarily of parallel, longitudinal yarns at least 10% of which have a high tensile strength and the remainder of which are yarns of the same type as the yarns of said bidirectional braids. An application in the construction of a bicycle frame is described.
