摘要： Polyolefin resin pre-expanded particles having two fusion peaks on DSC curve wherein the proportion of the heat of fusion Qh of the peak appearing on the high temperature side based on the total heat of fusion of the two peaks represented by the equation: [Qh/(Ql+Qh)]×100 falls within the range of 10 to 60% in which Ql is the heat of fusion of the peak appearing on the low temperature side, and the standard deviation of said proportion is not more than 1.2. The pre-expanded particles are prepared by releasing an aqueous dispersion of resin particles impregnated with a blowing agent from a vessel into an atmosphere of lower pressure than the inner pressure of the vessel to expand the particles, while stepwise or continuously raising the inner temperature or the inner pressure of the vessel at a specific rate, and can be molded with stable molding cycle to give cellular molded articles having stable dimensions.

摘要： There are provided a vehicle impact energy absorbing member which is arranged as an impact energy absorbing member of a simple construction capable of absorbing impact energy with high efficiency, and which is capable of improving the pedestrian protection performance as well as the passenger protection performance, and a vehicle impact energy absorbing structure using the vehicle impact energy absorbing member. More specifically, a compression energy absorbing member 10 using compression deformation and a buckling energy absorbing member 20 using buckling deformation are provided. Impact energy applied to a vehicle body is absorbed by a combination of the two energy absorbing members 10 and 20. Buckling energy absorbing portions 11a and 11b are also provided which have a buckling characteristic such that a peak value of impact force is equal to or smaller than a set value and in which a setting is made such that at least one of impact timing for starting absorption of impact energy and peak value timing for making the impact force have a peak value after collision is changed in a stepping manner or continuously. Impact energy applied to the vehicle body is absorbed by buckling deformation of the buckling energy absorbing portions 11a and 11b.
