Apparatus
A 30 kN MTS testing machine (Model: E45) was used to conduct this test.
A 50 mm displacement transducer was used to measure the elongation of the specimen.
Test Procedure
Tests were conducted under a temperature of 23°±3°C.
All specimens were loaded at a rate of crosshead movement of 2.0 mm/min until failure.
Load versus crosshead displacement data throughout the test method, maximum load, final load, and load at any obvious discontinuities in load-displacement data were recorded at a rate of 20 Hz.
Test Results
Five specimens were tested for each type of product. Tensile strength is calculated using equation 1.
High strength, unidirectional carbon fiber wrap pre-saturated to form a carbon fiber reinforced polymer (CFRP) wrap used to strengthen structural concrete elements.
