Effect of Triggering Mechanism and Variable Strain Rates on Energy Absorption of Glass Fiber Reinforced Polymer Tubes Under Quasi Static Compression

Abstract

Fiber-reinforced polymer matrix (FRP) composites have evolved as a prominent class of structural materials for usage as thin-walled impact-absorbing structural members in the case of industries such as aerospace, marine, and automotive. The experimental studies began with the literature survey, identification of the best method of the fabrication process, and new method of fabrication of specimen to trigger the steady crushing process. Which were then subjected to the axial compression test. The tubular Glass Fiber Reinforced Polymer (GFRP) composite tubes were made utilizing woven glass fabric plies in a manual wrap-up approach. The axial compression test was used to determine the absorbed energy of each GFRP composite at a variable strain rate. Finally, a relative assessment of the energy absorption capabilities of specimens was established in order to study deformation mechanism and their energy absorption capability
