Abstract
Textile structures for producing structural members such as reinforced spars of composite material and a method for producing the textile structures. In the textile structure at least two textile planar members, or plates, are integrally joined together by textile filaments such that the planes of the members intersect each other, at least one member being formed of layers of textile filaments which extend obliquely in at least two directions in a brace fashion with respect to the longitudinal and transverse directions of the member while the remaining members are each formed of layers of textile filaments extending along the longitudinal, transverse and vertical directions of the member. The textile structures are made by disposing filament guide members of required length in a vertical direction according to a desired configuration and design density of the structures and laying out textile filaments among said filament guide members so that they move longitudinally, transversely or orthogonally to form a plurality of textile planar members. The members are joined together by extracting the filament guide members and inserting filaments in the spaces vacated by the filament guide…
