Abstract

A module suitable for use in a crash barrier has a diaphragm with opposite first and second sides. First and second cellular foam blocks are coupled to the first and second sides of the diaphragm respectively. A wrap layer surrounds a periphery of the first and second cellular foam blocks. A sealant layer may be applied to the wrap layer. The wrap layer is configured as a metal cover member. A crash barrier may be configured with one or more modules. A method of manufacturing a module includes adhering first and second cellular foam blocks to opposite sides of a diaphragm and wrapping a wrap layer around a periphery of the first and second cellular foam blocks. A transition rail may be connected between first and second crash barriers.
