abstract

  • In this paper the ballistic behaviour of several glass/polyester laminate structures was studied, evaluating the residual velocity of the projectile and the damage area. Three monolithic laminates of different
    thicknesses and two multiplate laminate structures were analyzed: one
    of a sandwich type with face-sheets of glass/polyester and a foam core,
    and another made with the same face-sheet, which were separated by a
    distance equal to the thickness of the core. It was found that laminates
    of greater thickness show a larger damage area and a greater ballistic
    limit. The influence of the core on the ballistic limit of multiplate
    laminate structures is negligible but, nevertheless, the extension of
    the damage area in the back face-sheet is increased.
