 Filament wound interlaminate tubular attachment

Details
Inventors: Policelli, Frederick J.;
Assignee: Hercules Incorporated (Wilmington, DE)
Primary Examiner:

Attorney, Agent or Firm:

A hollow filament wound tube having a plurality of cylindrical, hollow, open ended load bearing shells embedded between radially spaced layers of fiber of the filament wound tube, the shells having a longitudinal dimension less than that of the filament wound tube.

DETAILED DESCRIPTION This invention concerns the mechanical joining of layered filamentary composite structural tubes containing a multiplicity of embedded load carrying shells to adjoining structures or structural fittings in an efficient manner as to transfer all essential loads or forces there between.
In particular the forces are first transferred principally by shear from the layers of the tubes into the intermediate shells and then in turn to the adjoining structure or fitting by means of fusion welding, mechanical fasteners or the like.
