A quick (and dirty) test was carried out by the White Label Space team to get a feeling for the strength of the insert joint located at the side of a piece of scrap CFRP sandwich panel. The insert survived the maximum applied static load of about 1.5kN. Without the appropriate test equipment to hand, the team decided to use an innovative 'dynamic' test technique to take the joint all the way up to its rupture load.
This test proved that the low-cost technique used make this joint is suitable for the lunar lander Structural Model that the White Label Space GLXP team is currently developing.
