Polyolefin film–reinforced composites for personal protection

摘要: This chapter describes the use of oriented films polyolefins in ballistic protective applications. The history their applications is briefly discussed, from early efforts World War II, through development stretched melt-blown tape-reinforced Vietnam War, solid-state extrusion (SSE) and then SSE with two stage drawing 21st century. Current film reinforcements are summarised, armour performance impact described compared to benchmark materials. Advantages that may be inherent film-reinforced composites including buoyancy, a unique combination high perforation resistance low dynamic deflection, cut relative ease attachment. concludes suggestions for heretofore unexplained observation polyolefin film–reinforced offer protection per weight far beyond than expected by specific axial strength, using rules thumb developed fibre-reinforced composites.
