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 self-crosslinking acrylic resin and/or at least one crosslinkable acrylic resin, and at least one tackifier. Compared with an article of the same construction but with a matrix material without 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 and the article passes the gasoline soak test. The article additionally comprising a plate of metal or ceramic exhibits minimal or even no delamination of the fibrous layers after ballistic attack, whereas an article of the same construction but with a matrix material without tackifier exhibits interior delamination of the fibrous layers.
