Abstract
Impact absorption energy measurements of three types of rolled-up steel plate composite were carried out at the temperature of -198, -87 or 20deg;C respectively. Geometrical construction effects on the absorption energy of the composites at low temperature were shown. Impact absorption energy of the composites was almost constant in the temperature range between -198 and 20°C and it was higher than that of low carbon steel at -196°C. Lower density was desirable for high impact resistance among the same type composite, particularly at low temperatures.
