Effect of humidity on quasi–static characteristics of foam CF–45 for TRL pedestrian legform impactor

The improvement of computer simulation technology allows car designers to evaluate injury risks of newly designed bumpers by using models of a car and TRL legform impactor. Since a conforTM foam type CF45 of the TRL legform impactor is not a non–ferrous material, the material property of compression characteristics should be clarified for the development of highly reliable TRL legform impactor model. The stress–strain characteristics of CF45 having 25 mm in thickness were investigated under quasi–static compression conditions. The humidity conditions were set at RH20%, RH35%, RH50%, RH65% and RH80%. The effect of humidity on the stress–strain characteristics of CF45 was discussed considering the stiffness of stress–strain.
