Title:
IMPACT-ABSORBING MEMBER
Document Type and Number:
WIPO Patent Application WO/2022/176661
Kind Code:
A1
Abstract:
Provided is an impact-absorbing member provided with an outer beam and an inner beam, wherein the inner beam is a fiber-reinforced plastic A and the impact-absorbing member achieves both high reaction force and work load by an impact-absorbing member that satisfies formulas (1) and (2) by using a ductile material that is not destroyed when impacted and ensuring the shape rigidity of the ductile material. Ba < Bb (1) R1 × 0.1 < R2 (2) Where, Ba: fracture deflection in a three-point bending deflection test of the inner beam, Bb: fracture deflection in a three-point bending deflection test of the outer beam, R1: peak value of reaction force in a three-point bending deflection test of the impact-absorbing member, R2: reaction force when the deflection value reaches Ba × 2 in a three-point bending deflection test of the impact-absorbing member
