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.
