Determine the relative peel resistance of adhesive bonds between flexible Adherends using a T-type specimen.
The T-peel test (ASTM D1876) evaluates the force required to the progressively separate two bonded, flexible adherends. Variations in test specimen preparation such adhesive curing, adhesive thickness, adherends and conditioning provides insight for optimization in processes and application.
Test Procedure:
Clamp each ends of the t-peel specimen in separate test grips of the universal tester / tension testing machine. Separate the specimen at a rate of 127 mm (5.0 in) /min for (5-in.) length of the bond line.
Specimen size:
Specimens are cut from a T-peel panel to 25.4 mm (1.0 in) long x 300 mm (12 in) wide. Ten specimens are tested.
Data:
Peel Load, Peel Strength (lb/in) and Type of Failure
