Araldite 2-component epoxy bond strength Analysis
Components in assembly:
1. Pipe (16 bar max) PVC
2. Turbidity sensor cup PP 20mm diameter
3. Adhesive Lining (Araldite 420 A/B epoxy)

TEST PLAN:
Failure Mode Effect Analysis (FMEA) (Abnormal condition setting)

 1. Tension on araldite adhesive 
     layer (0.1mm thick) 
 2. Pressure on turbidity sensor Polypropylene (PP) cup (4 bar) 
 3. PVC pipe fixed support at lower 
     end. Gravity not applied 
     (Inconsequential here)


Theoretical information on Araldite material used:
Lap shear strength after various cure times at 23-degree Celsius (for 0.10mm thickness)
 5 hours: 1 N/mm² 
 6 hours: 8 N/mm² 
7 hours: 9 N/mm²

The final result shows a maximum stress of 11 N/mm² (11MPa) on the PP turbidity sensor cup. Even less on the adhesive bond layer.

Tutorial project for a stress analysis of a connecting rod. The project only provides the geometry to start with. See our tutorials section to have a look at the step-by-step instructions to set up the simulation.
