Abstract
We provide a honeycomb component made of a fiber-reinforced composite material that achieves both lightweight properties and shock absorption characteristics. [Solution] A honeycomb member having a structure consisting of an aggregate of hollow columnar cells partitioned by cell walls, wherein the cell walls are composed of a porous fiber-reinforced composite material containing a discontinuous fiber base material (Ds) made of fibers (Cf), resin (Cr), and voids, and the density ρm of the cell walls is 0.1 to 0.8 g / cm³. 3 The honeycomb member is as follows: the ratio L / t of the circumference L of the columnar cells to the thickness t of the cell walls of the honeycomb member is 30 or more and 200 or less, and the thickness t of the cell walls is 200 μm or more and 1000 μm or less.
