FIELD: plastic processing.
SUBSTANCE: invention relates to the manufacture of composite structures and concerns radius fillers for composite structures that include radius fillers, systems and methods for their formation. Said method comprises the following steps: determining the shape of the cross-section of an elongated cavernous space that extends within a transition region formed by a plurality of layers of a composite material; determining the material properties field of the transition region; forming a radius filler by combining a plurality of segments of the composite tape to form the shape of the cross-section of the radius filler that corresponds to the shape of the cross section of the elongated cavernous space, and orienting a plurality of lengths of reinforcing fiber in each section of said plurality of segments of the composite tape on the base, at least in part, of the material properties field of the transition region. Radius fillers include radius fillers with selectively oriented reinforcing fibers.
EFFECT: invention makes it possible to duly control the shape and / or properties of radius filler materials and ensures that the shape and / or properties of the materials conform to the shape and properties of the materials of the surrounding installation.
