The paper describes the design, development and prototype testing of practical, effective FPR energy-absorbing modules for use on controlled deformation (energy absorbing) rear underrun barriers for heavy vehicles. The energy absorbing unit consists of two telescoping light weight steel tubes, containing the energy absorbing glas fibre reinforced composite tube. The system operates by crash of the comoposite tube within the larger diameter steel tube. The full system exhibits very good force-deformation characteristics, with energy absorption in excess of 40KJ. Testing has included static and dynamic loading of a variety of FRP tubes, and finally offset and full frontal impact crash testing of the prototype unit to compare the injury outcome with that of rigid barriers.
