ABSTRACT:
The invention concerns low density multichannel structures made of composites, processes and semifinished products for the manufacture thereof.
A multichannel laminated resin structure according to the invention includes cellular fabric (1) defining a row of parallel ducts in each of which is inserted a fitted tubular extrusion (3). The semifinished product is placed between the external reinforcement layers (4, 5). The cellular fabric and reinforcement layers are embedded in a curable resin (6).
One application is the manufacture of boat hulls or airframes for light aircraft, noncorrodible and very good mechanical properties.
