The Fracture Behavior of Random Fiber-Reinforced Composite Specimens: Experimental Investigation

Abstract

The aim of this work is to study the effect of tensile test on the fracture behavior of randomly distributed fiber composite specimens. Utilizing tension tests, an experimental analysis of the fracture behavior of random fiber-reinforced composites has been carried out. Continuous measurements of the COD were made while the applied load was being applied. To create the R-curves, the load-COD curves were employed (crack growth resistance curves). There have been a few analytical relationships discovered using the resulting R-curves. The fracture toughness has been anticipated based on these correlations. The results obtained from the present work provide a better understanding of the crack resistance characteristics of randomly distributed fiber composites. The results are very helpful to engineers and designers as they have now better insight regarding the fracture phenomenon of random fiber-reinforced composites.
