Abstract:
In the present study we investigate the effect of the time storage of the epoxy resin on the interlaminar fracture toughness of a three unidirectional carbon fibre. The interlaminar fracture behaviour was studied using the mode I, Double Cantilever Beam (DCB) test, the mode II, End Notched Flexure (ENF) test and a mixed mode bending (I/II) in order to determine the energy required for the initiation and growth of an artificial crack. The materials were made by a 32 stacking of unidirectional prepared carbon fibre. The matrix used was an epoxy of type (TGDMA) without a modification. The delamination energies of these three materials were compared in orders to characterize their mechanical properties.
