Insert design for sandwich (DLR)
Composite Joints and Inserts
 
A recently completed GSTP study by Patria Finavicomp addressed the technology and analysis for structural CFRP/honeycomb sandwich panel technology and sandwich panel insert design. A test program on open-hole CFRP sandwich specimens as well as on specimens with inserts was performed. Analytical models for sandwich and insert strength prediction were updated and validated.
 
The qualification of a new insert design for sandwich panels developed by the DLR Institute of Structural Mechanics, Germany, using carbon fiber tubes in sandwich panels is pursued in another project. These inserts have a lower mass than traditional potted inserts.

The results of these studies are being incorporated into an update of the ESA Insert Design Handbook.

On-going studies address for example the evaluation of

  • GFRP and CFRP fasteners and inserts for space applications and
  • hybrid titanium / CFRP laminates for space applications.
