  • Multilayer antiballistic structure
    Patent number: 5340633
    Abstract: A multilayer antiballistic structure having good antiballistic properties comprises a first layer which comprises ceramic tiles and a second layer of composite material which comprises polyalkene filaments having a tensile modulus of at least 40 GPa and a tensile strength of at least 1 GPa and a matrix which at least partially surrounds the polyalkene filaments, while the antiballistic structure comprises, between the first and the second layer an intermediate layer of a material having a flexural modulus which is higher than the flexural modulus of the composite material of the second layer and is lower than the flexural modulus of the ceramic material.Good results are obtained if the intermediate layer comprises a composite material.
