Abstract:
In an automotive structural member, weight efficiency of impact resistance is improved. An automotive structural member includes: a hollow member having plane portions; and an FRP member joined to at least one section of the plane portions, wherein: the FRP member is joined to a region of at least 0.1L1 to 0.9L1 of a length L1 in a longitudinal direction of the hollow member; the plane portion is formed with an FRP joint portion being a portion to which the FRP member is joined and an FRP non-joint portion being a portion to which the FRP member is not joined, in the region of 0.1L1 to 0.9L1; a total width of the FRP joint portion is 8 to 60% of a full width of the plane portion, in the plane portion; and a flexural rigidity of the FRP member in the FRP joint portion is 30 times or more a flexural rigidity of the plane portion excluding the FRP member in the plane portion.
