METHOD AND APPARATUSES FOR THE EXTRUSION OF THERMOPLASTIC ALVEOLAR STRUCTURES, AND STRUCTURES THUS OBTAINED

摘要

Fabrication by extrusion through a die of thermoplastic alveolar structures. According to the invention, said structures are subjected immediately at the outlet of the die to a tempering operation which is preferably previously accompanied by drawing and lamination. Application particularly to the fabrication of honeycomb structures in the form of beams, joists or plates.
