Thermoplastic seam welds

The present invention is a method for joining thermoplastic composite sandwich panels with thermoplastic welds (fusion bonds) made without autoclave processing of the joint. The preferred joint is a double interleaf staggered joint with supporting titanium doublers providing a tensile strength of at...

Beschreibung
Zusammenfassung:	The present invention is a method for joining thermoplastic composite sandwich panels with thermoplastic welds (fusion bonds) made without autoclave processing of the joint. The preferred joint is a double interleaf staggered joint with supporting titanium doublers providing a tensile strength of at least 12,000 lb/in. The joint is particularly suited for joining sections of a cryogenic tank for spacecraft.
