  • Publication number: 20130240150
    Abstract: A preform for the molding of a fiber-reinforced resin beam, the preform comprising: a reinforcing-fiber beam which has been formed from a reinforcing-fiber base made up of many reinforcing fibers and has a cross-sectional shape comprising at least one linear part and at least one curved part connected to the linear part; and a release sheet bonded and united through an adhesive resin to at least part of a surface of the reinforcing-fiber base along the lengthwise direction for the base. A process for producing a preform comprises: a step in which a continuous flat reinforcing-fiber base having a release sheet bonded and united to a surface thereof is shaped so that the cross-sectional shape of the base comes to have a curved part to thereby produce a preshaped object; and a preshaped-object uniting step in which the preshaped object is bonded and united to another preshaped object.

  • Patent number: 6591949
    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.
