The load level stability and the ratio of initial peak crashing force are generally improved with metallic reinforcements. ... Moreover, since the Al-CB7-4 tube contains a more amount of CFRP material, and the broken pieces of the CFRP in the crushed Al-CB7-4 tube is smaller than that in Al-(Al)CB7-1 tube, ...

This shows that crushed anthracite possesses layered and ordered re-crushing characteristics similar to crushed limestone [31]. The crushed anthracite in different layers might have attained different packing compactness values under axial loading. The load force is delivered from the upper loading piston to the bottom.
