CAERI Side Impact Moving Deformable Barrier AC-MDB

For C-IASI 2023 side impact crashworthiness evaluations

Share:

Based on Aluminum Honeycomb technology, the AC-MDB barrier (Side Impact Moving Deformable Barrier) is a new development barrier used in the C-IASI 2023 side impact crashworthiness evaluations.

AC-MDB barrier is designed by China Automotive Engineering Research Institute Co., LTD., developed jointly with Argosy XAC Composite Materials LTD., and produced by Argosy XAC Composite Materials LTD., which is suitable for China’s road conditions.

Technical Properties

The AC-MDB barrier consists of two parts: a Main Honeycomb Block and a Bumper Honeycomb Block. The Main Honeycomb Block comprises Six elements: two Upper, two Lower Side, and two Middle Bottom. The Bumper Honeycomb Block comprises three elements: one Middle and two Sides.

Upper Element Honeycomb Block 1-1 Material
Aluminum 3003 – cell size 3/4’’ Crush strength of 50 KPa

Upper Element Honeycomb Block 1-2 Material

Bumper Middle & Bumper Side Element Honeycomb Block 5 Material Aluminum 3003 – cell size 3/4’’ Crush strength of 320 KPa
Back plate Element – Aluminum 5052 H32/H34, T1.5mm

Middle Plate Element – Aluminum 5052 H32/H34, T=0.5mm

Front Plate Element – Aluminum 5052 H32/H34, T=0.7mm
Bumper Plate Element – Aluminum 5052 H22/H34, T=3.0mm

Adhesive:
Two-part Polyurethane

A complete testing procedure for certification of aluminum honeycomb is performed in-house according to C-IASI 2023 Side Impact Crashworthiness Evaluation, Moving Deformable Barrier Specification, and in accordance with the procedure defined by China Automotive Engineering Research Institute Co., LTD.

The aluminum honeycomb blocks are processed so that the force deflection curve, when statically crushed, is within the corridors defined for each block.
