Bonding Angle Data
Bonding Angle Performance Data
Queensland University of Technology (QUT)
Test report CET 4149/3 –
Tensile tests to fibreglass connections – fins.
Sample Data: Specimen 1 – polyester bonded : Specimen 2 – epoxy bonded
Test Equipment –
Grade A Tinius Olsen Universal Testing Machine, loading rate = 5mm/min
Test | SpecimenThickness | Nominal Area | Failure Load (kN)/ | Apparent Shear | |
---|---|---|---|---|---|
1 | 2 | Resisting Shear (mm2) | Failure Mode | Strength (MPa) | |
1 | 21 | 21 | 48,400 | 77.6 part shear through polyester bond : part tearing | 1.60 |
1 | 14 | 21 | 30,400 | 68.5kN shear through epoxy bond | 2.25 |
In both circumstances, failure of the joins was through the adhesive rather than the Bonding Angle.
