Abstract
Eight layered symmetric GFRP laminate was prepared by hand layup followed by press moulding. Samples were prepared according to ASTM D790-17 and were tested at three different strain rates of 1s-1, 10s-1 and 100s-1. Flexure properties of the samples being a matrix dominated property were found to be highly strain rate dependent. At the nominal and moderate strain rates of 1s-1 and 10s-1 samples showed a small variation in flexure strength and flexure modulus. While the same specimen when tested at 100s-1 depicted increased strength and modulus, while flexure strain decreased. Further numerical simulation of the test using shell model was carried out on ANSYS and results were found out to be well within experimental results.
