A Review on Mechanical Behavior of FRP Composites at Different Loading Speeds

AbstractFiber-reinforced polymer (FRP) composites are increasingly becoming suitable and durable materials in the repair and replacement of traditional metallic materials. The built-in promise of performance assurance and retention of structural integrity in harsh and hostile environments of these materials certainly offers an alternative and attractive avenue for a wider range application to explore its potential to the zenith. The toughest challenge faced by material scientists is to assess and ascertain its behavioral log in a range of loading rates. The heterogeneity and responses of multiple distinct phases to varying loading conditions are most often complex and far away from comprehensive conclusion. Furthermore, composites with common structural polymer matrices quite often absorb moisture during service period. Then, FRPs become a much more complex system to comprehend its sensitivity to experimental variation. The present article emphasizes the need for understanding this perpetual problem of FRPs which might pose a threat to its prospects.Keywords: fiberspolymer-matrix composites (PMCs)environmental degradationmechanical propertiesdurabilityloading rate ACKNOWLEDGMENTSThe authors greatly appreciate the support and suggestions forwarded by the Institute, and its people.
