Based on Aluminum Honeycomb technology, the SC-MDB-V2 barrier (Side Impact Moving Deformable Barrier) is a new development barrier used in the C-NCAP 2025 side-impact crashworthiness evaluations.
SC-MDB-V2 barrier is designed by CATARC, developed jointly with Argosy XAC Composite Materials LTD., and produced by Argosy XAC Composite Materials LTD., which is suitable for China’s road conditions.
The SC-MDB barrier consists of two parts: a Main Honeycomb Block and a Bumper Honeycomb Block. The Main Honeycomb Block comprises Six elements: three Upper and three Lower Elements. The Bumper Honeycomb Block comprises one element.
Upper Element Honeycomb Block 1 & 3 Material
Aluminum 3003 – cell size 1’” Progressive Crush strength according to CATARC Tech. Spec.
Upper Element Honeycomb Block 2 Material
Aluminum 3003 – cell size 1’” Crush strength according to CATARC Tech. Spec.
Lower Element Honeycomb Block 4 & 6 Material
Aluminum 3003 – cell size 1/2’’ Progressive Crush strength according to CATARC Tech. Spec.
Lower Element Honeycomb Block 5 Material
Aluminum 3003 – cell size 3/4’’ Crush strength according to CATARC Tech. Spec.
Bumper Element Honeycomb Block Material
Aluminum 3003 – cell size 3/4’’ Crush strength according to CATARC Tech. Spec.
Lower Front Plate Element – Aluminum 5754-O, T=0.5mm
Adhesive:
Two-part Polyurethane
A complete testing procedure for certification of aluminum honeycomb is performed in-house according to C-NCAP Side Impact Crashworthiness Evaluation, Moving Deformable Barrier Specification, and in accordance with the procedure defined by CATARC.
The aluminum honeycomb blocks are processed such that the force deflection-curve when statically crushed is within the corridors defined for each block.
