This chart shows the comparison of lap shear tests carried out in accordance to ASTM D5868-14: lap shear adhesion for FRP bonding.
The STAT system was used to texture an Aluminium alloy 6000 series sample that was then bonded to a carbon fibre reinforced polymer sample, which had a peel-ply textured surface. The graph is the culmination of over 140 individual tests.
As is shown, the performance of a STAT- textured sample is considerably better than the control where the metal was untextured but still with ply-ply and comparable to the grit blasted sample in performance terms, but gaining a much more consistent result.
Preparation of the STAT-produced sample also required no masking and produced almost zero waste in comparison to the grit blasted samples cutting out significant time and cost from the processing stage
