To study the effect of RGO additive on the creep deformation of the bonded joints, single lap joints
were manufactured according to ASTM D1002 using neat and modified adhesive.
For the single lap joints
production, a 2 components structural epoxy adhesive (Axson ADEKIT A140 and H9940), under form of paste, was adopted.
Furthermore, all field joints were specified to be welded, utilizing bell and spigot lap joints

A senior Boeing engineer said this month that the company normally did not expect that airlines would need to inspect the lap joints
for metal fatigue until an aircraft had completed about 60,000 flights.
Boeing has asked operators of certain 737-300, -400 and -500 airplanes at or above 30,000 flight cycles to inspect certain lap joints
every 500 cycles or less," she said.
The effect of shading on moisture entrapment in pine and maple L and lap joints
was evaluated in a moderate decay zone (Madison, Wisconsin).
A third option, a double lap joint
, is shown to overcome all of these issues, but the design and fabrication of the test sample is critical.
There was an explosion inside the furnace which both management and unions thought was of an unprecedented nature, causing tonnes of molten metal to emerge from the furnace around the lap joint
with tragic consequences to those in its path.
In successive joining operations, up to six layers are welded together as a lap joint
0 IPM crosshead speed and the force in pounds to break the lap joint
in shear was measured.
