Document Type and Number:
Japanese Patent JP4686955
Kind Code:
B2
Abstract:
The present invention is an impact energy absorption member that is characterized by comprising a long member of fiber reinforced resin having a lengthwise direction and a thickness direction, wherein the ratio of the thickness t (mm) of the long member to the length L (mm) thereof is within the range of 1/11000 to 6/1000 as well as the direction of an external force is substantially in agreement with the thickness direction of the impact member. The member of the present invention sufficiently absorbs impact energy from a moving body when collision occurs and greatly increases safety to collision of transportation equipment, for example, a motor car and the like as well as is light in weight and compact, whereby the member can improve resistance against environment and saves energy. Further, when this member is applied to a house and a building against which the transportation equipment may collide, it can reduce the loss of social properties.
