  • Patent number: 9341445
    Abstract: An antiballistic panel includes at least a first stack and a second stack. The first stack has a plurality of first laminates made of a first kind of fibers, and the second stack has a plurality of second laminates made of a second kind of fibers. Either the first kind of fibers or the second kind of fibers has a tensile modulus in the range of 40-85 GPa measured according to ASTM D7269. The other of the first kind of fibers or the second kind of fibers has a tensile modulus in the range of 86-140 GPa measured according to ASTM D7269.

  • Patent number: 9134096
    Abstract: A ballistic resistant article is presented comprising a plurality of fibrous layers, each of said layers comprising a network of fibers, wherein the fibers have a strength of at least 800 mN/tex (1100 MPa) according to ASTM D 7269-07 and a matrix material, wherein the matrix material comprises a mixture comprising: at least one styrene butadiene random copolymer resin, and at least one tackifier. Compared with an article of the same construction but with a matrix material without a tackifier the article according to the invention comprises a higher adhesion between the fibrous layers both in the unaged and aged state and a lower water pick up after water soak. The article additionally comprising a plate of metal or ceramic exhibits minimal or even no delamination of the fibrous layers after ballistic attack.
