摘要

The blast resistance of a carbon fibre-reinforced epoxy resin is investigated using a ballistic pendulum. Tests were undertaken at impulses up to those required to completely destroy the laminates. An examination of the damaged panels highlighted a number of different fracture mechanisms including delamination, top surface fibre buckling, fibre fracture and shear failure along the edges of the plates. The impulses associated with the onset of fibre fracture and complete target failure were found to increase in a linear fashion for the range of panels considered here. Tests on the carbon fibre reinforced epoxy showed that it offered a similar blast resistance to that of a thermoplastic-matrix composite.
