Abstract

© 2022, The Society for Experimental Mechanics.In this research, devulcanized recycled rubber modified phenolic epoxy based composites reinforced with different ceramic carbon, and/or glass fibres and also graphene nano plates (GnPs) based composites were designed for aircraft internal structure. After determination of the reinforcements and matrix, a hot bonding process was applied to complete successfully the manufacturing of these composites. After that, the relevant toughening mechanisms given by the reinforcements were analyzed in detail to evaluate the damage tolerance of aircraft internal structures. For this purpose, mechanical and physical properties, KIC—Fracture toughness stress intensity factor and GIc—Critical energy release rate in mode I) have been determined by fracture toughness tests (static 3P bending test with single edge notch specimens, drop weight test, etc.).
