摘要： The invention relates to a method for assembling elements of a structure comprising an alveolated honeycomb core by welding with the aid of electromagnetic radiation. According to the inventive method, the structure is based on a plastic material which is transparent with regard to electromagnetic radiation and at least one of the elements to be assembled comprises a layer which absorbs at least partially said electromagnetic radiation in the vicinity of at least one part of the surface thereof and welding occurs by melting said layer using electromagnetic radiation in the welding areas.

摘要： Process for manufacturing cellular structure based on a composition comprising an amorphous thermoplastic polymer and made up of sheets extruded in parallel and intermittently welded, according to which: - an amorphous polymer composition is chosen which has a dynamic melt viscosity, measured at its processing temperature and at an angular velocity of 0.1 rad/s, of less than 2000 Pa.s; and - the temperature of the coolant is regulated so that it is at least equal to Tg - 20°C, where Tg is the glass transition temperature of the composition based on the amorphous polymer.
