That is, material property of the forestay bar is utilized more than before, and its weight decreased successfully.
The ultimate tensile strength of a forestay bar made of 30CrMnSiNi2A is 1600MPa, so material property of the forestay bar is utilized more than before.

This core materials is a kind of reinforced foam core materials that can be formed by inserting the slender pultruded rods, Z-pins, in the foam matrix with definite angles [1].
Fig.2 SEM photomicrograph of the Z-pin’s end The two models’ material parameters were chosen according to the experimental materials.
The face-sheet and Z-pin are the same materials and the specific material properties are listed in Table 1.
