The 50% Overlap Suitable for China Mobile Progressive Deformable Barrier (SC-MPDB) is used for frontal impact crashworthiness evaluations in C-NCAP 2027.
The impact barrier consists of four aluminum honeycomb blocks covered by cladding and a cover plate. Blocks 1 and 4 have constant impact deformation forces, while blocks 2 and 3 exhibit progressive forces as deformation increases.
