Examples of Evaluation Methods of Energy Absorbing Properties for Interior Occupant Protection

摘要

The automotive interior finishing materials, such as plastic foams, elastomers, and hollow-shaped plastics, were evaluated with the high-speed impact test in addition to the static compression tests. We have found that the high-speed impact tests together with proper data analyses are very effective in evaluating energy-absorbing (E/A) properties of various plastic materials. Foamed plastics are focused on and some typical plastic foams are additionally tested under various conditions.
