Flexural Analysis on GFRP Composites Subjected to Cyclic Gradual Load and Cyclic Impact

Abstract

Glass fiber reinforced polymeric (GFRP) composite laminates have been prepared by hand layup method. According to ASTM standard, the test specimens have been prepared to carry out the flexural bending tests. The specimens have been subjected to both cyclic impact load and cyclic gradual load with various frequencies prior to the flexural bending analysis. Three point bend method has been adopted to find out the flexural strength and flexural modulus. Flexural strength and modulus have been calculated from the load deflection curve obtained from the tensometer for respective specimens. The flexural bending properties of GFRP composites subjected to cyclic gradual load and cyclic impact have been compared and found that the GFRP composite materials are effective for gradual cyclic load than the cyclic impact load.

Influence of SMA Short Fibers on Mechanical Properties of Copper/GFRP Composites

“…SMA incorporated copper/GFRP laminates were prepared by hand layup method as described in our earlier work [7]. Figure 1 shows the photograph of fabrication process of laminate.…”
