SMAR 2024 – 7th International Conference on Smart Monitoring, Assessment and Rehabilitation of Civil Structures Comparative Assessment of FRP Composite Materials in Structural Applications under Low-Velocity Impact Loads: A Review Haider Mraih a *, Javad Hashemi a , Robin Kalfat a , Riadh Al-Mahaidi a , Guoxing Lu a a Swinburne University of Technology, John Street, Hawthorn Victoria 3122, Australia Abstract Fiber-reinforced polymer materials (FRPs) have been investigated as enhancing materials for various structural members against impact loading. This study reviews and highlights the impact resistance properties of structural members strengthened with different composite strengthening materials, explicitly focusing on vehicle collisions with bridge elements. While most existing research concentrates on the effectiveness of carbon fiber-reinforced polymer (CFRP) against impact loads, this study explores the performance of alternative materials. Comparative studies, including assessing aramid fiber-reinforced polymer (AFRP) versus CFRP, suggest that AFRP exhibits superior anti-impact mechanical properties, including enhanced energy-absorbing capacity. However, contradictory findings necessitate further investigation. Moreover, Dyneema ® fiber-reinforced polymer (DFRP) emerges as a promising alternative with superior anti-impact mechanical properties compared to CFRP. Despite this potential, DFRP has not yet found widespread application in structural contexts. This research aims to bridge existing gaps in understanding practical applications for strengthening materials against impact loading. The presentation will include quantitative insights into the comparative performance of different materials and discuss the findings' potential implications for future structural engineering applications. © 2024 The Authors.
