PROCEDE ET DISPOSITIF DE FABRICATION DE PLAQUES COMPOSITES

摘要

A process for manufacturing composite sheets. The sheets are made of at least one ply of yarn with this ply having at least two materials with different melting points. The ply is introduced continuously into a zone where it is heated to a temperature between the two melting points and below the degradation temperature of the material having the lower melting point. This ply is then passed over at least one rotating bar heated to a temperature lying between the melting points and below the degradation temperature of the material with the lower melting point. The ply is then compressed on leaving the rotating bar and is cooled to form a composite web. The web is collected in the form of one or more composite plies.
