Filament winding process chain

Schematic of filament winding process chain (includes preheating zone and a consolidation roll). 

As shown in Fig. 7.2 the main steps of the filament winding process chain are the material supply, tension build-up, heating and consolidation. Depending on the individual winding equipment configuration and winding head technology several different setups are possible. 

The first step in a filament winding process chain is the material rack. The fiber material, whether already impregnated, that is tape material, or not, that is, roving material, delivered on spools is mounted here. The number of spools depends on the winding head technology used and the components dimension. In addition to the material storage, a spool creel can also be... 

Consolidation and development of interlaminar bond strength for thermoplastic matrix composites have been modeled by two mechanisms intimate contact and autohesion. Intimate contact describes the process by which two irregular ply surfaces become smooth (Fig. 13.10). In areas in which the ply surfaces are in contact, autohesion occurs, and the long thermoplastic polymer chains diffuse across the ply boundaries. Filament winding with thermoplastic matrix materials is considered an on-line consolidation process in that local...
