Abstract
Abstract Material useful in bullet-proof clothing is formed from a number of laminates arranged one on top of another. The laminates are preferably formed of a substrate coated with a crushed thermosettable foam that is, in turn, covered with a surface film, which may be an acrylic polymer. The films should form the outermost layers of the composite material which, together with the foam layer, prevent degradation of the substrate, which is typically formed of fabric woven from Kevlar.
