ABSTRACT:
Thermoplastic matrix composite cylinders, pipes, and other hollow bodies are formed by a winding technique using thermoplastic filaments. The filaments are fed from a vertically moving winding head onto the surface of a rotating mandrel. The filaments are preheated to soften them and then pass beneath a heated compaction roller bearing against the mandrel. The compaction roller is castered so as to follow a helical path. Several plies of the thermoplastic material may be laid down in this fashion, the surface of each prior ply being heated so that the layers fuse properly. When cooled to below its solidification temperature, the formed object is removed from the mandrel.
