Crack Propagation Fracture Toughness of GFRP Composite Repairs
This paper discusses work carried out to characterize glass fiber/polymer composite repairs through mixed mode I – mode II testing. Repairs conducted with different repair parameters were investigated. Parent plates were manufactured using vacuum assisted resin transfer molding and these were ground down to simulate removal of damaged part. The ground surface was then repaired using hand lay-up. Specimens were cut and tested under mixed mode loading. Calculations were carried out to determine the fracture toughness of the various kinds of repairs in order to compare them. Included in the paper are details of manufacturing the specimens, testing set-up, testing conducted, and results obtained along with the discussion of the effects of various repair parameters on the fracture toughness of the repairs.
