Dunlop Composite Energy Absorbing Bumper Systems 750010

This paper describes the application of composite laminates consisting of bonded rubber and plastic layers to discrete energy absorber units and flexible bumper systems.
These laminates are manufactured by the fusion bonding technique applied to injection moulding of discrete EA units and thermoforming of resilient EA bumpers.
The two material construction allows greater design flexibility in unit and system design. The properties of the dual material system permit a high ratio of energy absorption per unit weight coupled with full recovery of pre-impact configuration.
The performance and installation requirements of the ‘V’ shaped discrete bumper mountings is described in detail. Experimental developments in fully flexible bumpers are then discussed.
