This report presents the experimental results from the investigation of the effect of increasing the stacking sequence of GLARE. Tensile tests and flexural tests were performed to determine the physical properties and performance of the GLARE specimens. GLARE 2/1, 3/2 and 4/3 were tested and documented in this report. The first chapter of the report consists of a literature review of related work, test methods and findings from various research papers. Then the specifications of the GLARE specimens used in the tests are presented. The next chapter of the report studies the tensile properties of GLARE 2/1, 3/2 and 4/3. The tensile test was tested with an Instron Universal Testing Machine and the GLARE specimens were tested until failure to capture the parameters, specifically the applied load to failure, maximum tension and tensile strain. The tensile stress-strain curve was obtained to formulate the Young’s Modulus for each GLARE type. The next chapter of the report studies on the flexural properties of GLARE 2/1, 3/2 and 4/3. The flexural test was tested with an Instron Universal Testing Machine as a three point bending test. The GLARE specimens were tested until excessive slippage occurred or to failure. Strain gauges were mounted on specimens to capture the strain separately. From the tests, the maximum flexural load, maximum flexural stress and maximum flexural strain could be obtained. The last chapter of the report continues on the flexural properties of GLARE 2/1, 3/2 and 4/3. Instead of three point bending test, the flexural tests were repeated with both ends of the GLARE specimen fixed. With the change in boundary conditions, all the specimens were tested until failure. The results from the flexural tests returned reverse results as the three point bending test. GLARE 2/1 could withstand the highest flexural load followed by 3/2 and then 4/3 which was opposite of the results from three point bending test.
