Abstract (en)
[origin: EP0768507A1] The invention relates to a ballistic-resistant article containing a compressed stack of monolayers, with each monolayer containing unidirectionally oriented reinforcing fibres and a matrix consisting of a polymer, the fibre direction in each monolayer being rotated with respect to the fibre direction in an adjacent monolayer. The moulded article has both a high structural stiffness and dimensional stability and a high protection level and a low trauma effect because the monolayer has a fibre content of between 20 and 145 g/m<2> and a matrix content of at most 25 wt.%, the reinforcing fibres are aramid fibres and the matrix polymer has a modulus of elasticity of more than 200 MPa.
