Method of making complex hollow pieces by uniaxial hot pressing composite material with a vitreous mould and pieces derived from said method

摘要

Introducing into a space delimited by the walls of a mould a sufficient quantity of a material required to obtain the final composite, placing in the material movable inserts corresponding to the hollow sections of the final piece, applying to the unit a uniformly distributed mechanical pressure under heat, extracting the material from the mould and mechanically removing the movable inserts from the material. Structural pieces formed of sandwich panels incorporating an internal stiffener.
