Abstract

A composite bumper structure is made up of an elongated molded bumper section, molded attachment lugs and energy absorbers. The bumper section is integrally molded with the lugs and both contain elongated reinforcement fibers. The energy of a collision is absorbed both by the deformation of the energy absorbers and the elastic deformation of the lugs. The bumper section may also support a stylistic facade.
