Method and tool for forming and assembling composite beams

Torna indietro

Abstract

A tool (21) for forming a C-section beam made of carbon fibre comprises a straight elongated mandrel (22) with a rectangular or trapezoidal cross-section. The mandrel has three consecutive outer faces, with a planar face (24) configured to form a surface of the web of the C-section beam, and two opposing lateral faces (26, 27), configured to form two respective surfaces of the flanges of the C-section beam. The mandrel has a distributed perforation (34) on at least one of the three outer faces (24, 26, 27) and an inlet/outlet connection (41) in order to connect the mandrel to an external source of vacuum and/or compressed air. Passages (31, 32) are formed inside the mandrel so as to establish a fluid communication between the distributed perforation (34) and the inlet/outlet connection (41). Through the distributed perforation, a vacuum is applied to the interface between the mandrel and the C-section beam so as to retain the C-section beam on the mandrel while this is lifted and turned upside down by 180° for coupling to a similar C-section beam in order to assemble an H-beam. Applying compressed air through the perforation (34) facilitates the removal of the C-section beam from the mandrel at the end of the compaction step.
