COMPOSITE RIB DEVELOPMENT. FINAL REPORT

Several attempts have been made to improve the thorax design of the Hybrid III dummy. While the Hybrid III thorax provides the most biofidelic response of any previous anthropomorphic dummy, the polyviscous damping material backing the steel ribs is temperature sensitive. Because of this temperature sensitivity, temperature maintenance in automotive crash testing environments is important, but often difficult and expensive. For this reason, the reduction of temperature sensitivity is desirable. In addition, difficulties with reliability of the damping material results in the replacement of ribs after about thirty impact tests due to fatigue cracks. Finally, there was an interest in the development of a ribset which provided more realistic localized deflection when loaded by various restraint systems. Based upon these considerations, it was determined that it might be feasible to employ composite materials to accomplish these improvements, since they are known to have good properties over a broad temperature range, provide some damping, and can be molded into complex shapes.
