PROBLEM TO BE SOLVED: To provide a crash box provided with an impact absorption material comprising a fiber-reinforcement resin with easy molding and high yield ratio of a raw material capable of being provided with required mechanical strength by the small number of laminatings. SOLUTION: A reinforcement fiber is knitted to a cylindrical shape by a braiding method to be made to a reinforcement fiber knitted body 3. It is crushed to a flat shape to be made to a flat reinforcement fiber knitted body 4 and it is formed to a stereometric shape. The reinforcement fiber knitted body 5 formed so as to become the stereometric shape is placed in a molding die 10, and it is made to the impact absorption material 7 comprising the fiber-reinforced resin in which the reinforcement fiber and the resin are integrated by an injection molding method. It is made to the crash box 9 using the same. COPYRIGHT: (C)2009,JPO&INPIT |
