Abstract: An adjustable length composite push rod constructed of a composite bar having two specially shaped ends to which metal end fittings bond via mating surfaces provided thereon for evenly distributing mechanical stress from the metal end fittings to the composite bar. The bar is constructed of a plurality of layers of sheets of thermosetting, epoxy impregnated, longitudinally oriented fiber material that form the inner portion of the push bar and a single outside sheet of thermosetting, epoxy impregnated, woven fiber material forms the outside portion of the bar.
Abstract: Flexible elongate web structures with reflective faces are fixed on opposing ends of a support arm which is centrally mounted over a highway barrier. Appropriate geometric structure and material selection provide a non-destructive bending response for the respective web structures during vehicle impact and provide for restoration to original orientation. The support or mounting arm is formed of polymer material having sufficient rigidity to support the web structure during static conditions and sufficient compliance and flexibility to bend and twist during the vehicle impact.
