ABSTRACT:
Extensible structures are made by partially embedding a selected knitted glass fabric into a perhalopolyfluoroethylene polymer resin sheet. The embedding can be done by pressing the glass fabric into one surface of the sheet heated to a temperature at which it is soft. The resultant composite structure is thermoformable into such shapes as a dished head. The exposed surface of the glass fabric can be impregnated with a castable material useful for such purposes as adhering the composite structure to a substrate such as a metal surface or for reinforcing the composite structure. The composite structure instead of being thermoformed can be rolled and seamwelded into a cylinder shape which can be used as a cylindrical tank lining or as a duct.
