Abstract (en)
[origin: WO2012007674A1] The invention relates to a method for manufacturing a composite material core. Said method comprises carrying out the following steps: manufacturing three composite material bars (3, 4) having selected sizes and including reinforcing fibers embedded in a thermosetting matrix or thermoplastic matrix; manufacturing two foam bars (6) having selected sizes; assembling and adhering the bars together such that the three composite material bars (3, 4) form a structure (5) having an H-shaped cross-section, and such that the foam bars (6) are inserted into the spaces defined by the composite material bars (3, 4) so as to obtain a composite block; tying up the composite block by winding reinforcing wires (82); and then coating same with resin and pressurizing same until it is polymerized.
