Abstract
A composite structural article, of preferably metal and thermoplastic material is described. The composite structural article comprises: (a) at least one reinforcing element (2) having sized openings (20); and (b) at least three profiled sections (1, 3, 4). A portion of each profiled section (1, 3, 4) is connected interlockingly with a portion of the reinforcing element (2). At least two of the profiled sections (1, 3, 4) have terminal portions each having a projecting region (5) that engages interlockingly with the sized openings (20) of the reinforcing element (2), such that a portion of the reinforcing element (2) surrounds at least partially the projecting regions (5). The profiled sections (1, 3, 4) are further joined to the reinforcing element (2) by means of thermoplastic material (11, 13) injected in the region of each interlocking connection with the reinforcing element (2). In addition, one of the profiled sections (3) is in at least one of: (i) an abutting relationship with at least two of the profiled sections (1, 4); and (ii) an interlocking relationship with at least two of said profiled sections (1, 4). Articles that may comprise the composite structural article of t…
