Interlaminar delamination fracture toughness of carbon/epoxy material IM7/8552 is investigated under mode I and mode II loading conditions. Material was manufactured in the form of unidirectional plates with Teflon insertion. RTU prepared the specimens and performed DCB and ENF tests. DCB tests was performed in order to obtain the mode I delamination fracture toughness at the 0/0 interface of the present laminated composite material. ENF tests was performed in order to obtain the mode II delamination fracture toughness at the 0/0 interface of the material.
