Abstract
A multi-branch fitting includes at least three branches, molded from a composite material and, more precisely, from a fiber-reinforced thermoplastic or thermoset matrix. The fitting is intended for assembling components which are at an angle to one another. There are at least three flat or substantially flat branches or flanges extending radially from a joining zone, and at least one face or part of a face constituting a bearing face for one or more of the components that are to be attached. The joining zone has a cross section, in the transverse direction, in the shape of a polygon with concave sides. The connection of each of the branches or flanges with another adjacent branch or flange is achieved through a portion in the shape of a curved blade which gives the joining zone one of its concave shapes.
